Pitting stainless steel
WebApr 15, 2024 · Chemical Composition. The chemical composition is the main difference between AISI 316 and 316L Stainless Steel. AISI 316L contains a lower carbon content than AISI 316. As a result, AISI 316L has a higher corrosion resistance than AISI 316. Additionally, the weldability of AISI 316L is better than that of AISI 316. Web316L stainless steel (316L SS) is a flagship material for structural applications in corrosive environments, having been extensively studied for decades for its favorable balance between mechanical and corrosion properties. More recently, 316L SS has also proven to have excellent printability when parts are produced with additive manufacturing …
