SS 304 304L Pipe
SS 304 304L Pipe
304L belongs to the American standard austenitic stainless steel, the implementation standard: ASTM A276/A276M-2017
304L is a variant of 304 stainless steel with a lower carbon content and is used in applications where welding is required. The lower carbon content minimizes the carbides precipitated in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.
