Overview
316L is the low-carbon version of 316. The reduced carbon prevents chromium carbide precipitation in weld zones, so welded assemblies keep their corrosion resistance.
Mechanical properties are marginally lower than 316; corrosion performance is the same or better.
Key Properties
Typical values from the MatWeb datasheet for AISI Type 316L Stainless Steel, annealed plate. Machined parts take the properties of the stock they are cut from.
