ASTM A240 is a standard covering chromium, chromium- nickel, and chromium- manganese- nickel stainless steel plate, sheet and strip for pressure vessels and for general application. S30908 is a kind of high temperature resistant stainless steel with excellent heat resistance and antioxidant properties.
Production process of ASTM A240 S30908/ 309S stainless steel 309S stainless steel is commonly produced through the electric arc furnace (EAF) or basic oxygen furnace (BOF) processes followed by refining in an argon oxygen decarburization (AOD) converter. The ingot or continuous cast slab is then hot rolled, cold rolled, or cold drawn into various shapes and sizes.
