316L / 316 Stainless Steel

Stainless Steel 316L is the low carbon content version of 316 Stainless Steel. Stainless Steel 316L is used in heavy-gauge welded products (over approximately 6mm). One advantage of Stainless Steel 316L over 316 Stainless Steel is that it is more resistant to carbide precipitation and can be used in the 425-860 degrees Centigrade range, if certain types of corrosion resistance are an important factor. If there is the threat of corrosion in the heat-affected areas of weldments, Stainless Steel 316L should be used.

316 Stainless Steel offers better creep resistance at higher temperatures and greater strength than Stainless Steel 304. In the annealed state, Stainless Steel 316 is non-magnetic, but can become slightly magnetic if it is extensively cold worked; further annealing would be necessary to correct this. Stainless Steel 316 cannot be hardened using thermal treatment; however, by cold working Stainless Steel 316, hardness and strength can be significantly increased.

Primary Elements: Stainless Steel 316 is an austenitic stainless steel that is Chromium, Nickel and Molybdenum alloy. The addition of Molybdenum, not found in Stainless Steel 304, gives Stainless Steel 316 increased corrosion resistance in highly corrosive surroundings, such as a seawater or chloride environment.
