904L Material introduction

904L (UNS N08904) belongs to austenitic stainless steel, and its corrosion resistance is higher than SUS 316L and SUS 317L. Due to the addition of Cu (1.5%), it has excellent corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid, and is widely used in complete chemical equipment. The company can supply forgings, flanges and pipe fittings.
