ASTM 309S stainless steel bar is a lower carbon variant of 309 stainless steel used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, which can lead to intergranular corrosion (weld erosion) of stainless steel in some environments. ASTM 309S stainless steel barhas excellent corrosion resistance and mechanical strength.
