Stainless Steel 310 / 310S Buttweld Fittings are widely utilized in fields that require endurance and resistance to high and low temperatures. Some of these applications include furnace parts, heat treatment tools, kilns, and incinerators. Their oxidation and scaling resistance is very high, making them the perfect choice for petrochemical, refinery, and power generation facilities. 310S finds particular favor in welded structures where carbide precipitation is to be kept to the lowest. These fittings are employed in steam boilers, exhausts, and heat process piping systems as well and provide a satisfactory service life while ensuring stable working in high temperature and corrosive conditions.
