Stainless Steel 347/347H Forged Fittings
Stainless Steel 347/347H forged fittings are stabilized austenitic alloys offering exceptional resistance to intergranular corrosion due to the addition of columbium (niobium) and tantalum. They maintain high strength at elevated temperatures ranging from 800°F to 1500°F (427°C to 816°C). These fittings are suitable for welding and standard shop fabrication, making them ideal for harsh industrial environments.
