Stainless Steel 347 Sheets, Plates & Coils are high-performance austenitic stainless steel products engineered for demanding industrial environments. Steel Icon Stainless Pvt. Ltd. delivers these materials to meet the evolving requirements of industries such as power generation, petrochemical processing, aerospace, and heavy structural fabrication. Designed to perform under high temperatures and corrosive conditions, these products provide reliability where failure is not an option. Their consistent mechanical strength and resistance to intergranular corrosion make them a preferred choice for fabrication and structural engineering projects.
Stainless Steel 347 is a stabilized austenitic grade that contains niobium, which enhances its resistance to carbide precipitation during welding and high-temperature exposure. The chemical composition typically includes chromium, nickel, and niobium, allowing the material to maintain structural integrity even after prolonged exposure to elevated temperatures. Stainless Steel 347 Sheets, Plates & Coils exhibit excellent oxidation resistance and retain their mechanical properties in high-temperature service environments. The material also demonstrates good toughness at cryogenic temperatures, making it versatile across a wide range of applications.
From a metallurgical perspective, the addition of niobium helps stabilize the alloy by preventing chromium carbide formation at grain boundaries. This characteristic significantly improves corrosion resistance, particularly in welded structures. These products also offer good formability and weldability, which simplifies fabrication processes in industrial manufacturing.
