Difference:

 

316 and 316L stainless steel:
316 and 316L stainless steels are molybdenum-containing stainless steels. The content of molybdenum in 316L stainless steel is slightly higher than that of 316 stainless steel. Because of the molybdenum in steel, the overall performance of this steel is better than 310 and 304 stainless steel. Stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack, so it is usually used in the marine environment. 316L stainless steel has a maximum carbon content of 0.03, which can be used in applications that cannot be annealed after welding and require maximum corrosion resistance.
