Stainless Steel 347 Round Bars and Rods are a type of austenitic stainless steel that is stabilized with niobium, which helps prevent intergranular corrosion and boosts high-temperature performance. Typically, their composition features 17–19% chromium, 9–13% nickel, up to 0.08% carbon, along with trace amounts of manganese, silicon, and niobium. These bars and rods are known for their remarkable mechanical strength, stability at high temperatures, and good weldability. In terms of mechanics, they boast a tensile strength ranging from 515 to 750 MPa, a yield strength of about 205 MPa, and a hardness of approximately 170 to 200 HB, ensuring they can handle tough environments with ease.
