The Stainless Steel 309H Sheets and Plates consist of 22–24% chromium, 12–15% nickel, and a higher carbon content (0.04–0.10%) to boost high-temperature strength. This alloy provides a tensile strength ranging from 550 to 750 MPa and a yield strength of about 205 MPa. SS 309H excels in oxidation resistance up to 1000°C and demonstrates good creep resistance under thermal stress. It remains non-magnetic in its annealed state and maintains ductility and toughness even after prolonged exposure to high heat, making it an excellent choice for applications that demand thermal endurance and corrosion resistance.
