If you need durability and strength for environments that face prolonged high temperatures, Adam Stainless’s Stainless Steel 347H bars are the perfect choice.
Stainless Steel 347H is an austenitic stainless steel alloy that contains about 17–19% chromium, 9–13% nickel, and is stabilized with niobium (columbium) to stop carbide precipitation. The “H” in its name signifies a higher carbon content (usually between 0.04% and 0.10%) compared to standard 347, which boosts its creep resistance and mechanical strength when the heat is on. This alloy delivers tensile strength between 515 and 620 MPa and yield strength close to 205 MPa, along with excellent oxidation resistance up to 925°C.
