The stainless steel 304H pipe（S30409）is the high carbon version of 304 and are known for its excellent heat resistance. It can resist atmospheric corrosion, as well as, moderately oxidizing and reducing environments, has been widely used in oil and gas industry equipment: offshore platform, heat exchanger, underwater equipment, fire equipment; Chemical processing industry; Desalination, high-pressure RO equipment and submarine pipelines; Energy industry such as power plant desulfurization and denitrification FGD system, industrial washing system, absorption tower; Mechanical parts (high strength, corrosion-resistant, wear-resistant parts). The 304H steel pipe and tube is specified in various dimensional specifications like ASTM A213, ASTM A240, ASTM A269, ASTM A312, ASTM A358, ASTM A376, ASTM A409, ect.
