The 316L stainless steel grade has less carbon than 316 stainless steel, offering better corrosion resistance after welding or stress relieving. It is a common choice when the material cannot be annealed after it has been welded. An austenitic stainless steel, 316L is typically nonmagnetic and can be cold worked to increase its hardness and strength while maintaining most of its formability.
