625 Alloy (also known as Alloy 625, Grade 625/2.4856) has wide application in areas requiring High Strength, Corrosion Resistance and/or High Temperature Performance.
The Nickel Chromium Molybdenum base alloy was developed to provide serviceability in extreme operational environments.
Therefore, due to its performance capabilities at elevated temperatures, pressures and corrosive conditions, 625 Alloy is commonly found in Aerospace, Marine and Offshore operations.
625 Alloy is a nickel chromium molybdenum alloy known for:
This material can be used successfully in extreme industrial conditions because it has high enough strength to withstand these conditions compared to standard Stainless Steel.
In addition, Alloy 625 / 2.4856 is found in:
The severe environments of aerospace and marine industries present a multitude of stresses on various materials including:
Therefore, a material that can maintain its properties at high temperature and corrosive exposure will provide an advantage with respect to longevity of the equipment. 625 Alloy is one material that provides this type of property for a number of aerospace and marine industries. Therefore, many aerospace and marine industries choose 625 Alloy for their applications when there is a need for prolonged operation and maximum operational safety.
625 Alloy does a great job in corrosive environments with chemical, saltwater or chloride exposures.
The alloy remains strong and stable at higher temperature levels; 625 Alloy is ideal for aerospace as well as exhaust gas applications.
It has a low rate of oxidation while continuously being heated. The application of this is very prevalent in aerospace as well as the exhaust side of jet engines.
The alloy will remain tough when put under pressure and/or subjected to mechanical stress within an industrial environment.
This alloy lends itself to the processes used in industrial manufacturing (e.g., forming, welding etc.).
Many aerospace components work at high temperature ranges. Other ordinary materials can degrade as a result of being exposed to such high temperatures. 625 Alloy is widely used because it handles:
This makes it suitable for:
Metals used in marine and offshore environments are exposed to both sea water and chlorides that cause a variety of types of corrosive attack including:
Because 625 Alloy has such good resistance to all three forms of corrosion, it is well suited to be used as materials for marine or sea water applications.
The ability of 625 Alloy to resist corrosion will support its use over the long term on:
