What is 347H Stainless Steel Round Bars and Rods?

**Stainless Steel 347H Round Bars and Rods** consist of roughly 17–20% chromium, 9–13% nickel, and a carbon content of up to 0.10%, and niobium (columbium) stabilizes them to resist carbide precipitation. This alloy offers better strength at higher temperatures and good corrosion resistance. Mechanical properties are tensile strength of 550–750 MPa, yield strength of 240–275 MPa, and elongation of around 35%. The material, **Stainless Steel 347H Round Bars and Rods**, is excellent in creep resistance at high temperatures, in structural stability, and weldability for applications in pressure-containing and thermal conditions.
