Stainless steel welding and rust free capabilities.

Author - Venuswires

While the iron was discovered through crude metallurgical techniques centuries ago, steel is a fairly late invention and has defined the human progress in more than one ways! The reason is the exceptional qualities adored by steel and which are highly desirable also. Steel is actually an iron alloy of precision wherein carbon, a non metallic and very common element of nature is invariably a component. The presence of carbon makes the steel what it is and particularly determines the arrangement of atoms in a manner such that sturdiness is optimized. Stainless steel is yet another increment in the segment of steels and in this, chromium is added which develops a layer of chromium oxide that is rust proof for life apart from delivering a lustrous finish. Stainless steel manufacturers make different grades of steel through precise alloying compositions towards serving the niche segments of the manufacturing economy around the world.

Stainless steel finds swift acceptance!

On account of the rust resistance and high strength attributes of steels, these are used in diverse applications; and the same are expanding at a fast pace. The sectors that relied on wrought iron as the base product are also transitioning to the SS as the base material; the example of balusters and hand rails could be counted in this regard. Stainless steel suppliers and manufacturers have expanded their portfolio and making newer primary products to meet the requirements of the secondary manufacturers and ancillaries. While the cost of making steel is an important determinant, the processing of the same is also important; as any discrepant conditioning like in welding,etc. could generate problems related to rust and corrosion in specific environs. Hence the steels processing and particularly the welding is guided by a set of protocols to ensure that the prime qualities of stainless steel are retained or at least optimized.

Ensuring rust resistance of SS

While stainless steel is ideally rust proof, continued pro corrosion environmental conditions could be still detrimental and cause the steel structure to get rusted in course of time. The sea coast and swimming pools can be counted as such conditions where the effects of salt water, moisture are much pronounced. The SS quality, therefore, means much to ensure that the durability of the external chromium oxide layer is maximized. Apart from 304 and 316, the stainless steel manufacturer are engaged in refined techniques and making the manipulations towards improving the resistance against rust and corrosion. Regular cleaning is also recommended to remove the corrosion products that accumulate at the SS layer.

The welding of stainless steel

Welding precautions for the SS include aligning the gaps in a precise manner so that the empty spaces are plugged properly. The use of specialty TIG welding is also done to ensure that the joints do not become prone to rusting processes. The welding techniques differ depending upon the use of the stainless steel structure. More refined welding and greater precautions are required in rust prone situations while the sturdiness needs to be double ensured in cases requiring critical frameworks like in construction activities.

Do you know difference between CARBON AND STAINLESS STEEL

Do you know difference between carbon and stainless steel?

Author - Venuswires

We all have witnessed heavy deployment of steel in various areas – construction of bridges, railway lines, and buildings, and fabrication of process equipment, machines, Automotives etc. It is worthwhile to note that steel types used for the above-mentioned applications are not same and they can either be stainless or carbon steel based on the necessity of mechanical properties and corrosion preventive measures. So, what exactly is the difference between carbon and stainless steel and how it influences the decision of selection? Let us understand.

Generally speaking, steel is an alloy made out of elements such as iron and carbon and the composition of them makes all the difference. While higher carbon content in the steel makes it be hard and brittle, the lower values make it tough and ductile. Hence the core differences between carbon steel and stainless steel can be made in several aspects such as composition, wear and corrosion resistance explains a reputed steel manufacturer in India.

Steel composition:

As the name implies, carbon steel contains much higher carbon than the stainless counterpart. While the former has 0.12 to 2% carbon, the latter has much lesser values. Also, it should be noted that the total alloy content in carbon steel is less than 10.5 percent and in the case of stainless steel, the quantum of chromium alone is at least 10.5 percent.

Corrosion resistance:

It is true that both carbon steel and stainless can be polished to achieve a shiny surface. But in the case of carbon steel, the surface needs to be protected with suitable paint to avoid rusting and this is not so with stainless steel. And the reason is quite simple – the presence of chromium in stainless steel provides an oxide shield for this material and hence offers excellent corrosion resistance against most of the known chemicals.

Mechanical properties:

The quantum of alloying elements defines mechanical properties such as hardness, tensile strength, brittleness and ductility in steel. For instance, nickel in stainless steel gives adequate ductility to it and thereby makes it tougher. As these alloying elements are the main feature of deciding the crystal lattice structure of steel, their composition plays a crucial role in mechanical properties. Remember, it is very much difficult to categorically classify steels on mechanical properties, as numerous varieties of stainless steel with unique compositions of alloying materials have been developed for industrial applications.


When it comes to aesthetic appearance, stainless steel easily outweighs carbon steel, as it does not lose its luster easily. Hence carbon steel needs to be painted routinely to avoid corrosion and thereby to retain the aesthetic appearance it offers to the job.


No comparison in engineering products would be complete without the comparison of cost. As carbon steel alloy is devoid of many costly elements, it is natural for them to be economical than stainless steel. The cost of stainless steel is completely dependent on their other alloying materials, but all their variants are definitely costlier than carbon steel.

Choosing the right quality of steel is a tricky subject and usually, the decision is made after weighing all these factors. If you are looking out for reliable stainless steel manufacturers in India for your industrial needs, contact us to know how we can help you with a selection of right material.

What is the role of steel in aircraft

What is the role of steel in aircraft?

Author - Venuswires

A good grasp of technical knowledge encompassing mechanical properties, chemical composition, and corrosion resistance of the material is crucial to design and fabricate any critical equipment such as those used in the aircraft industry. As any deviation in design parameters can lead to catastrophic losses of human lives and equipment, proper selection of material is nothing but an essentiality. Some of the design properties that are considered crucial for aircraft industry are

• Ductility
• Elasticity
• Malleability
• Strength
• Density
• Weldability
• Conductivity
• Thermal expansion
• Toughness
• Brittleness

Considering the unique needs of the aircraft industry, stainless steel manufacturers in India and other parts of the world in conjunction with Society of Automotive Engineers (SAE) and American Iron and Steel Institute (AISI) have identified the chemical composition of stainless steel that can withstand the rigid demand of service.

Low carbon steels:

Steels having carbon percentage of 0.1% to 0.3% are employed by aircraft industry for safety wires, fasteners, bushings for cables, pipe clamps and threaded solid tie rods.

Medium carbon steels:

Having a carbon content of 0.3% to 0.5%, this type of steel is highly suitable for machining connecting rods and light forgings with sufficient surface hardness.

High carbon steels:

Thanks to the high carbon content of 0.5% to 1.05%, this type of steel enjoys very high hardness after heat treatment. But it has very less application in the aircraft industry, except for flat and coil springs.

Nickel steels:

As nickel steels present an excellent opportunity to achieve high hardness without much effect on ductility, they are widely used as fasteners, pins, and keys.

Chromium steels:

Many times, heat treated forgings with ultra high strength and toughness superior to carbon steel is necessary for ball bearings in aircraft, and what can be a better choice other than chromium steels? It fits the bill perfectly!

Stainless steels:

With strong anticorrosion properties even in aggressive process conditions, SS makes a strong candidate for many applications in the aircraft industry. Also with excellent workability, it can be rolled, drawn, formed, or bent to any shape using proper tools.

o Fuel tanks and cabin components:

With high suitability for mild environments of chlorine percentage less 200 ppm, SS 304 and SS 316 are the perfect solutions. Remember it is possible to withstand very high temperature using the derivatives of these highly popular stainless steel variants.

o Exhaust components and high-temperature engine parts:

As high-temperature service and oxidation prevention requirement propels the need for variants other than SS 304 and 316, the steel industry presented the variants ASTM S30415, ASTM S30815, AISI 309, and 310 that can withstand up to 1150oC.

Chrome molybdenum steels:

As these types of steel have very high UTS without compromising wear resistances, they have replaced carbon steel for welded structural parts, components, and assemblies.

Well, the list goes on and on. The bottom line is that the contribution of steel in industries, particularly the aircraft industry, is beyond match and highly irreplaceable. Being a reputed steel manufacturer in India, we are glad to be of service to aircraft industry and be part of a success story.

Author - Venuswires

Before the advent of stainless steel, food and dairy industries were facing huge problems with respect to corrosion. As food and dairy industries need to maintain strict hygiene conditions and product purity, the corrosion in pipelines, equipment, and fluid handling machinery were always creating severe problems of business enterprises, explains one of the steel manufacturers in India. But since the arrival of stainless steel, an overwhelming change of scenario was observed and the reason was quite obvious – zero or very minimal chances of corrosion. So how exactly it helps the dairy industry? Let us learn

Corrosion resistance: As mentioned earlier, corrosion resistance property of SS has always been the pushing factor. Even in harsh conditions such as elevated or subdued conditions of temperature, specially formulated SS 304 and SS 316 materials offer excellent corrosion resistance, especially to oxidation and sulfidation. Be it for homogenizer, decanter, heat-exchanger, process tanks and pasteurizer, SS has become the norm in the dairy industry. Moreover, all fittings, valves, fluid transfer systems, and instruments extensively use SS to pave way for non-corrosive operation.

Ease of fabrication: When any material is chosen, it is also necessary to gauge several other factors such as engineering economics and fabrication feasibility. As it is a known fact that SS is recyclable material, engineering economics has always been with SS. But what about technical feasibility or ease of fabrication? With a plethora of options available for welding and fabrication, and easy availability of good quality of welding wire, machining equipment, SS ranks very high in the popularity chart, emphasizes a reputed stainless steel supplier

Heat resistance: Perhaps this is what triggered the necessity of a special focus on new materials. But thanks to huge advances in metallurgical industry and automation techniques, good quality SS with unconventional designs and manufacturing techniques popped up and aided dairy industry.

Flavor and color retention: As the chances of oxidation or other chemical reactions were eliminated by using SS, dairy industries were able to control the flavor and color of their products ranging from milk, butter, cheese, and curd. Remember, in addition to product purity, flavor and color retention is very much important in food and dairy industry to sustain the interest of consumers.

Cleanability: A big plus point of SS is that it can be cleaned very easily. As unclean or unhygienic conditions can easily deteriorate the product quality, the dairy industry never takes chance with cleanliness and hence it is no wonder they chose SS.

Although stainless steels are quite resistant to corrosion, the conventional formulations of them may cause a stain or even undergo mild corrosion due to malic acid and lactic acids at higher temperatures. Moreover, average values of thermal conductivity of SS were also a major concern for engineers. But after understanding the metallurgical needs, methods, and development of new technologies of fabrication, this problem has been smartly eradicated.

Twisting The History Of Steel Wire Rope

Author - Venuswires

Durability & creativity are the backbone of technological progress of a country. A special mention to be made here is that of mining industry which led the Industrial Revolution & has gone down in history courtesy few significant innovations. Steam Engine would probably be the frontrunner in the list of strategically significant key innovations. We must not ignore the contribution steel wires in the development of heavy industries; they always seem to have been left alone & the limelight is grabbed by the final product i.e steam engines.

For more than a hundred years, flexible steel wire ropes have been a pillar of support for lashing down scaff planks or lifting heavy weight pulleys. They were in usage as cranes & draglines for surface mining. Cheaper imports from China have started flooding the market however Venus steel, the undisputed leader in manufacturing of wire rope works still stands tall when it comes to manufacturing & production of flexible steel wire ropes. Of late VenusWires have set up their manufacturing unit in Khopoli, Maharastra to empower Indian heavy industry.

We can attribute the first usage of steel rope to Willhelm August Julius Alber, a German mining engineer in 1834 based on our research through the pages of mining history. Till then, mining haulage was dominated by hemp fibre rope or chains. Rope would get rotten due to extreme humidity of underground mines & iron chains often had a layer of rust making both of them lose their strength of load bearing capacity. Technically, they had to be replaced every now & then. Chains were more prone to loss of credibility arising out of inconsistency in metallurgy & a single unnoticed weak link could prove to be a disaster for the entire unit.

Owing to this inefficiency & costly affair, a German engineer & surveyor, John Roebling focused his entire energy in building ropes made up of flexible steel wires. He used 6/19 construction wherein 6 denotes strands & 19 is the number of wires per strand. A strand containing 19 wires looked like a perfect hexagon as due care was taken to ensure the gauge of all the wires are the same. Roebling used three different gauges & combined all of them together to develop a stronger & more durable flexible steel wire rope. It immediately enhanced the load bearing capacity of the wire & effortlessly replaced erstwhile ropes & chains. Roebling saw an increased demand of his steel wires across civil engineering, mining industry as well as transportation industry increased their demand for his products. Sensing profit & strategic benefits, John Roebling set up his first rope factory in 1849 in Trenton, New Jersey.
