Factory Manufacturers 904L Stainless Steel Pipes and Tubes of Seamless / Welded / ERW / EFW Suppliers in China, Contact US Buy ASTM A312 UNS N08904 Pipe

904L stainless steel pipe is suitable for the chemical industry. The addition of copper to N08904 material improves resistance to strong reducing acids such as sulfuric, phosphoric, and acetic acids, surpassing traditional chromium-nickel TP316/L and TP317/L stainless steels. Its lower carbon content makes it easier to weld, and its high-temperature resistance reaches approximately 450°C.
Our supplier offers both welded and seamless AISI 904L pipe. We manufacture in strict accordance with ASTM A312 standards, and every 904L pipe is supplied in the heat-treated condition. Contact us for more information and pricing.
