High-performance stainless steel 321H sheets and plates are manufactured and supplied by the reputable company Kunj Sheets and Plates, which is based in Chennai, India. Kunj is well-known for their expertly designed stainless steel solutions, which offer superior resistance to oxidation and high temperatures. A high-carbon version of stainless steel, 321H, is made to be stronger and more resistant to creep at higher temperatures. The petrochemical, power generation, aerospace, and furnace manufacturing industries all make extensive use of Kunj’s products. Kunj Sheets and Plates provides long-lasting, corrosion-resistant, and customised products for vital industrial applications thanks to its sophisticated manufacturing infrastructure and stringent quality control procedures.
Stainless Steel 321H is an austenitic stainless steel alloy with a higher carbon content (0.04–0.10%) for enhanced high-temperature strength, and roughly 17–19% chromium, 9–12% nickel, and titanium stabilisation. It has an elongation of 40%, a yield strength of 205 MPa, and a tensile strength of roughly 515 MPa. Particularly after welding, the titanium addition improves resistance to intergranular corrosion. 321H is perfect for high-heat applications because it retains its mechanical strength and resistance to oxidation at temperatures as high as 870°C. It stands out in demanding thermal environments due to its exceptional structural stability and creep resistance.

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.
In high-temperature applications where durability and resistance to oxidation are essential, stainless steel 321H sheets and plates are frequently utilised. They are utilised for heat exchangers, piping systems, reactor vessels, and furnace components in the petrochemical and oil and gas industries. 321H is used in the power generation sector for exhaust ducts, superheaters, and boiler casings. Because of its ability to withstand mechanical stress and scaling, aerospace manufacturers use it in engine parts and thermal shields. Additionally, it is used in food processing facilities and chemical processing equipment. 321H is perfect for components subjected to prolonged high temperatures because of its weldability and stability under heat.
