About 316L stainless steel
316L is widely used in the chemical industry because of its excellent corrosion resistance. 316L is also a derivative steel of 18-8 austenitic stainless steel, with 2 ~ 3% Mo element added. On the basis of 316L, many kinds of steel are also derived, such as 316Ti after adding a small amount of Ti, 316N after adding a small amount of N, and 317L after increasing the content of Ni and Mo.
About 304L stainless steel
304L is a variant of the lower carbon 304 stainless steel for use in welding situations. The lower carbon content minimizes the carbide precipitation in the heat-affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments.
