The Stainless Steel 304/304L Flanges belong to 304 grades that have an excellent durability and can be forged into many shapes. The 304 L type stainless steel is the extra low carbon version of the 304 grade steel. This minimizes the harmful carbide perception that occurs as a result of welding. This grade has somewhat lower mechanical properties but can be applied to a variety of uses.
