Stainless Steel 347 and 347H are austenitic, niobium-stabilized stainless steels designed for high-temperature and corrosive environments. Niobium is added to prevent chromium carbide precipitation, thereby protecting against intergranular corrosion. The primary difference between these grades lies in the carbon content—347H has a higher carbon level, which enhances high-temperature strength and creep resistance.
