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.
Stainless Steel 321H Plates and Sheets find extensive applications where there are high-temperature strength and oxidation as well as corrosion resistance needs. Typical applications are in heat exchangers, boiler fittings, furnace components, and exhaust manifolds in aerospace as well as automotive sectors. They find extensive use in chemical processing plant as well as refinery applications for processing hot organic and inorganic chemicals. The high formability and weldability of the alloy render it ideal for construction and architectural fabrication. Furthermore, Stainless Steel 321H is a suitable material for high-temperature operating pressure vessels and piping systems, promoting safety and longevity.
