1285C

1285C is a type of stainless steel, specifically a member of the 1200 series of stainless steels. It is an austenitic stainless steel, which means it has a face-centered cubic crystal structure. This structure provides 1285C with excellent corrosion resistance, making it suitable for a wide range of applications where resistance to oxidation and corrosion is required.

The chemical composition of 1285C typically includes chromium, nickel, and manganese, with smaller amounts of other elements. The chromium content, usually around 18-20%, is the primary element that provides corrosion resistance. Nickel, typically around 5-7%, further enhances the corrosion resistance and improves the steel's strength and ductility. Manganese, usually around 1-2%, contributes to the steel's hardenability and strength.

1285C is known for its excellent resistance to pitting and crevice corrosion, making it suitable for use in marine environments and other applications where exposure to saltwater or other corrosive substances is likely. It also has good resistance to stress corrosion cracking, which makes it suitable for use in applications where the steel is subjected to both stress and corrosion.

The mechanical properties of 1285C are generally good, with a tensile strength of around 550-650 MPa and a yield strength of around 200-300 MPa. It has a good balance of strength and ductility, making it suitable for a wide range of applications, including structural components, pressure vessels, and heat exchangers.

In summary, 1285C is an austenitic stainless steel with excellent corrosion resistance, making it suitable for use in a wide range of applications where resistance to oxidation and corrosion is required. Its good mechanical properties and resistance to stress corrosion cracking further enhance its suitability for use in demanding environments.
