Stainless steel AISI S32304
Data sheet
EN 10088-3
Grade 1.4362 / AISI S32304
The material 1.4362 / AISI S32304 is an austenitic-ferritic duplex steel that has a high acid resistance. It serves as a substitute for the austenitic material 1.4404 / AISI 316L. Due to its two-phase structure, stainless steel 1.4362 / AISI S32304 is strongly superior to austenitic stainless steels with regard to intergranular corrosion and stress corrosion cracking. The material has very low magnetisability and can be used for welding and forging. However, stainless steel 1.4362 / AISI S32304 is only conditionally suitable for cold forming due to its higher basic strength.
