Stainless Steel 316L

316L is the low carbon version of 316 and is immune to sensitization (grain boundary carbide precipitation. 316L is commonly used in heavy gauge welded components. As an austenitic grade 316/316L also has excellent toughness, even down to cryogenic temperatures.

When compared to chromium-nickel austenitic stainless, 316L offers higher creep, stress to rupture and tensile strength at elevated temperatures.
