Difference Between 316 and 316L
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 content, the overall performance of this steel is better than 310 and 304 stainless steel. 316 stainless steel has good resistance to chloride attack, making it suitable for marine environments. 316L stainless steel has a maximum carbon content of 0.03%, which makes it ideal for applications that cannot be annealed after welding and require maximum corrosion resistance.
