Stainless steel is a corrosion-resistant alloy with a minimum of 10.5% chromium content by mass. It comes in various types and grades suitable for different applications. Below is a summary of the various types of stainless steel with their respective forms:
- Austenitic Stainless Steel - This type of stainless steel is highly corrosion-resistant and has good weldability and formability. Grades SS316, SS316L, SS304, SS304L, SS310, SS321, SS317, and S347 belong to this group. They are available in forms of Wire Rod, Rolled Round Bars, Square, Hex, Bright Bars & Forged Bars, Blocks, Die Block, Forging Ingots, Flats, Sheets, Coils, Angles, Plates & Pipes.
- Martensitic Stainless Steel - This type of stainless steel is known for its high strength and hardness. Grades SS410, SS420, SS431, and SS416 belong to this group. They are available in forms of Rolled Round Bars, Bright Bars & Forged Bars, Flats, Sheets, Coils, Angles, Plates & Pipes.
- Ferritic Stainless Steel - This type of stainless steel has good corrosion resistance and high-temperature resistance. Grade SS409 belongs to this group. It is available in forms of Sheets, Coils, Angles, Plates & Pipes.
- Precipitation Hardening Stainless Steel - This type of stainless steel has high strength and corrosion resistance. Grade 17-4PH belongs to this group. It is available in forms of Rolled Round Bars, Blocks, Die Block, Flats, Sheets, Coils, Angles, Plates & Pipes.
- Stainless Steel Alloy - This type of stainless steel is a combination of different elements that offer unique properties. Grade 440C belongs to this group. It is available in forms of Rolled Round Bars, Flats, Sheets, Coils, Angles, Plates & Pipes.
