AISI 316 vs 316L Stainless Steel, Difference of SS316
Since SS 316L has a much lower carbon content than SS316, the welding of 316L stainless steel is better than SS 316. In addition, AISI 316 might lead to stress-corrosion cracking or dimensional instability in service after welding, so postweld heat treatment is required for stress relief to reduce intergranular corrosion or stress-assisted ...
