Varun Sheets and Plates is a well-respected manufacturer and supplier of Stainless Steel 321H Sheets and Plates based in Dubai, UAE. We pride ourselves on delivering top-notch products specifically designed for high-temperature and pressure applications. Stainless Steel 321H is a stabilized austenitic stainless steel that boasts a higher carbon content, which enhances its creep strength and stress resistance when exposed to elevated temperatures. Our 321H sheets and plates are crafted to meet international standards, ensuring they have an excellent surface finish, precise dimensions, and robust mechanical integrity. We cater to various industries, including petrochemical, thermal processing, and power generation, providing reliable and durable stainless steel solutions.
The composition of our Stainless Steel 321H Sheets and Plates includes 17–19% Chromium, 9–12% Nickel, and a higher Carbon content (0.04–0.10%) compared to 321, along with Titanium for stabilization. This unique blend offers outstanding resistance to intergranular corrosion after welding and maintains high strength at elevated temperatures. The mechanical properties feature a tensile strength ranging from 515 to 730 MPa, a yield strength of about 205 MPa, and an elongation of 40%. Additionally, 321H retains good toughness and ductility, making it an excellent choice for structural and pressure-related components that face high thermal conditions.

Stainless steel 321H sheets and plates provide excellent corrosion resistance, especially in high-temperature environments. They are extremely durable, resistant to oxidation, and are curing up to 870°C (1600°F). The intergranular corrosion resistance makes them ideal for welding-related applications. The stability of the composite is enhanced by the addition of titanium, which helps prevent carbide precipitation. Stainless steel 321 is also known for its durability, durability and ability to maintain structural integrity under extreme conditions. These properties make it suitable for industries such as aerospace, chemical and power generation.
Our Stainless Steel 321H Sheets and Plates find extensive use in high-temperature and high-stress environments, such as furnace parts, heat exchangers, boiler components, and expansion joints. They are particularly well-suited for petrochemical processing, power generation plants, and thermal oxidizers due to their impressive resistance to oxidation and creep deformation. Furthermore, 321H is utilized in refinery equipment, aircraft exhaust manifolds, and food processing applications that demand thermal stability. Its excellent weldability and corrosion resistance make it a dependable option for ensuring both structural integrity and longevity in challenging industrial settings.
