Stainless Steel 347H Circles

Stainless Steel 347H circles are manufactured from an austenitic stainless steel that is stabilized with niobium (formerly called columbium). This alloy is intended to have enhanced high-temperature characteristics and immunity to intergranular corrosion. The make-up of Stainless Steel 347H is about 17% chromium, 9% nickel, and 1% niobium. It has a higher carbon content than 347 Stainless Steel, which may increase to 0. 2%. This high-carbon version of 347 increases its high-temperature strength.
