Stainless Steel 347 Forgings are an austenitic stainless steel grade that is stabilized with niobium, offering excellent protection against intergranular corrosion and high-temperature oxidation. This grade typically contains 17–19% chromium, 9–13% nickel, ≤0.08% carbon, along with trace amounts of niobium, manganese, and silicon. In terms of mechanical properties, 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. These forgings retain impressive strength and ductility even at elevated temperatures, ensuring good weldability and toughness. Their unique blend of corrosion resistance, durability, and thermal stability makes them ideal for demanding industrial and engineering applications.
