Stainless Steel 309H Sheets and Plates are top-notch austenitic stainless steel products crafted by Nizar Sheetsandplates in Amman, Jordan, specifically designed for applications that demand high-temperature and corrosion resistance. The “H” grade, which has a higher carbon content, provides enhanced tensile strength and creep resistance when exposed to elevated temperatures. These sheets and plates are meticulously rolled to ensure smooth surfaces, uniform thickness, and reliable mechanical performance. Various industries in Jordan depend on SS 309H Sheets and Plates for components like furnace parts, heat exchangers, boilers, and industrial frameworks, where exceptional high-temperature strength, oxidation resistance, and long-lasting durability are crucial for dependable structural and mechanical performance.
Stainless Steel 309H Sheets and Plates are composed of 23–25% chromium and 12–15% nickel, along with a higher carbon content (0.08–0.15%) that boosts high-temperature strength and creep resistance. The austenitic structure guarantees excellent ductility, toughness, and stability under thermal stress. SS 309H showcases outstanding tensile strength, oxidation resistance, and scaling resistance at high temperatures. This material retains its mechanical integrity in high-heat environments and offers good weldability and formability. Its unique blend of corrosion resistance, high-temperature stability, and mechanical strength makes it perfect for demanding industrial and structural applications.
