ASTM A358 EFW 310 Pipes

ASTM A358 EFW 310 Pipes

ASTM A358 EFW 310 Pipes are high-chromium, high-nickel stainless steel welded pipes manufactured using the Electric Fusion Welding (EFW) process. They are designed for superior performance in high-temperature and corrosive environments.

Grade 310 stainless steel provides excellent resistance to oxidation and corrosion at elevated temperatures, making it ideal for furnaces, heat exchangers, chemical processing, and other high-temperature industrial applications.
