Multipurpose 304 Stainless Steel
From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
304/304L stainless steel contains less carbon than standard 304 for better weldability.
Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.
