S31703 Corrosion resistant Stainless Steel Summary


Compared with the conventional chromium - nickel austenitic stainless steel alloys such as 304, has stronger resistance to chemical corrosion. In addition, compared with the conventional stainless steel, alloy sus317l has higher ductility, stress corrosion resistance , compressive strength and high temperature performance. It is a low-carbon level or L level, this level has resistance to sensitization in during welding and heat treatment process.
 

Delivery State


Generally heat treatment state of delivery, the type of heat treatment should be indicated in the contract, not indicated, according to the state of non heat treatment delivery.
