309 Series Stainless Steel Plate

309L is a variation of low carbon 309 stainless steel used for welding applications. Lower carbon content can minimize carbide precipitation in the heat-affected zone near the weld, which can cause intergranular corrosion (weld erosion) of stainless steel in some environments.

Compared with 309S, 309 does not contain sulfur S content. 309S is a sulfur-containing free-cutting stainless steel. Used for occasions with free cutting, curved surfaces and high gloss content
