EXCELLENCE & EXPERTISE in manufacturing Stainless Steel Wires & Bars since 1990.


We provide ferrite no as per WRC 1992. based on the chemical composition of weld metal.

The Austenitic grades don’t stick to magnet in solution annealed condition, but after doing cold work (Wire drawing) it results in partial transformation austenite to martensite, This increase in cold work forms the martensite phase resulting to material become magnetic.

  1. Tensile strength is the resistance of steel to breaking under tensile tension.
  2. The maximum force required to break the object per unit cross-sectional area to break the object.

Yield strength is the maximum stress that can be applied before it begins to change shape permanently.

yes, it is, because it has a minimum of 11 % of chromium as an alloying element. Chromium reacts with oxygen on the property of corrosion resistance. hence it protects the steel from the corrosion hence it is called stainless steel.

Stainless steel is available in various grades. Tougher higher grades will also contain a different combination of alloying element accordingly the properties vary.

Yes, it can be welded successfully, need to control the impurities and the proper selection of the filler metal based on the material on which it has to be welded.

The popular finishes in stainless steel are two, one is matt and another is bright. However, there is a different customized requirement from the customer meets based on the applications or the treatment to be done on the steel to produce finish product.

  1. Stainless steel is more corrosion resistant than carbon steel, however, there a variety of stainless steels that can be selected based on the requirement of the end product,
  2. comparatively the strength of stainless steel is higher than the mild steel, however, both the steel has a wider range of grades, based on the chemical composition and heat treatment, the mechanical properties can be modified.

There are types of stainless steel, such as Austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and ph stainless steel, among that the Austenitic stainless steel is non-magnetic.

There are many AISI product specifications as below,

  • ASTM A 240 Standard Specification for Chromium and Chromium-Nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications.
  •  ASTM A 276 Standard specification for stainless steel bars and shapes.
  •  ASTM A 313 Standard specification for stainless steel spring wire.
  • ASTM A 314 Standard specification for stainless steel Billets and Bar for forging
  • ASTM A 479 Standard specification for Stainless steel bars and shapes for use in boilers and other pressure vessels
  • ASTM A 480 Standard specification for General requirement for flat-rolled stainless and heat-resisting steel plate, sheet and strip.
  • ASTM A 484 Standard specification for general requirements for stainless steel bars, billets, and forgings.
  • ASTM A 493 Standard specification for stainless steel wire and wire rods for cold heading and cold forging.
  • ASTM A 555 Standard Specification for General requirements for stainless steel wire and wire rods.
  • ASTM A 581 Standard specification for free machining stainless steel wire and wire rods
  • ASTM Ad 582 Standard specification for free-machining stainless steel bars.
  • ASTM A 492 Standard specification for stainless steel rope wire.
  • The SS304 contains a minimum of 18% chromium and 8% nickel while SS316 contains a minimum of 16% chromium, 10% nickel and 2% to 3% molybdenum.
  • Type 316 has more resistance to corrosion due to the addition of alloy molybdenum compared to Type 304,
  • The cost of Type 304 is comparatively low compared to Type 316.
