309S Stainless steel Hexagonal steel
309S IS A free cutting stainless steel containing sulfur, used for the main requirements of free cutting and high surface smoothness. 309s is a variant of 309 stainless steel with a lower carbon content for use where welding is required. The low carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may cause intergranular corrosion (weld erosion) in stainless steel in some environments.
