Stainless Steel 347/347H Forged Fittings are stabilized austenitic stainless steels, primarily made up of chromium and nickel, with columbium (niobium) added to prevent intergranular corrosion. The Grade 347H variant features a higher carbon content, which boosts its strength at elevated temperatures. These fittings boast impressive mechanical properties, including high tensile and yield strength, good creep resistance, and durability under thermal stress. Built to meet standards like ASTM A182, SS 347/347H forged fittings are reliable performers in high-temperature and high-pressure settings.
