316L grade stainless steel is similar to 316 in stainless steel, but it contains lower carbon content. Therefore, 316L stainless steel thick sections do not require post annealing.

316L (1.4404) | 0030 | 2.0 | 0045 | 12:03 | 1.0 | 16.0-18.0 | 10.0- | 2.0-3.0 between |
Due to the chemical content of 316L grade stainless steel and lower carbon content compared to 316 stainless steel, it is recommended that 316L grade stainless steel be preferred if parts are to be welded.
