304L

304L stainless steel is a low-carbon austenitic stainless steel, a variant of 304 stainless steel. Its main feature is that it has stronger resistance to intergranular corrosion during welding or stress release, while retaining the strength, corrosion resistance and good processing properties of 304 stainless steel. Due to its low carbon content (≤0.03%), it can effectively prevent intergranular corrosion cracks in the welding area even without heat treatment.
