Stainless Steel 347H Round Bars and Rods are an austenitic stainless steel grade that’s stabilized with niobium to prevent intergranular corrosion and ensure outstanding performance at high temperatures. Typically, their composition features 17–19% chromium, 9–13% nickel, 0.04–0.10% carbon, along with trace amounts of manganese, silicon, and niobium. These bars and rods are known for their high tensile strength, durability, and resistance to creep at elevated temperatures. In terms of mechanics, they boast a tensile strength ranging from 515 to 750 MPa, a yield strength of about 205 to 275 MPa, and a hardness of approximately 170 to 200 HB. Their unique blend of corrosion resistance and high-temperature stability makes them perfect for various industrial and engineering applications.
