At Adinox Overseas, we take pride in being a leading manufacturer, supplier, and exporter of premium quality Stainless Steel 321 Sheets. Our sheets are produced in compliance with international standards including ASTM A240 and the UNS S32100 specification. Stainless Steel 321 is a titanium-stabilized austenitic stainless steel known for its exceptional resistance to intergranular corrosion and superior high-temperature strength.
Stainless Steel 321 is an ideal choice for applications where heat resistance and resistance to oxidation are paramount. The addition of titanium in the alloy ensures stabilization against chromium carbide formation, which makes it suitable for prolonged exposure to temperatures in the range of 800–1500°F (427–816°C). Our SS 321 Sheets are highly recommended for use in the aerospace industry, chemical processing, heat exchangers, and exhaust systems.
Adinox Overseas delivers top-quality ASTM A240 SS 321 Sheets that are manufactured using premium raw materials and advanced technology. These sheets offer outstanding weldability and formability, along with excellent mechanical strength and corrosion resistance. The sheets are available in various finishes such as No.1, 2B, BA, and mirror finish, and we provide customized sizes and thicknesses to meet client specifications.
The SS 321 Plates we offer exhibit excellent resistance to oxidation at temperatures up to 900°C. They maintain their structural integrity and strength under thermal cycling and fluctuating heat loads, making them the go-to material in furnace components and thermal oxidizers. Our stainless steel sheets are compatible with standard fabrication techniques including welding, forming, and machining, making them versatile and easy to work with across various applications.
