Stainless Steel 321 Sheet & Plate Manufacturer, Supplier & Exporter in India
Stainless Steel 321 Sheets & Plates from Astromet Steel & Engineering are titanium-stabilized austenitic stainless steels designed for high-temperature service. The titanium addition prevents carbide precipitation, improving resistance to intergranular corrosion.
SS 321 offers excellent oxidation resistance and mechanical stability at elevated temperatures. It retains strength and toughness even after prolonged exposure to heat, making it suitable for thermal cycling applications.
These plates provide excellent weldability and fabrication properties without the need for post-weld heat treatment. Their durability ensures long operational life in demanding environments.
Manufactured as per ASTM A240 standards, SS 321 Plates deliver consistent performance in heat-intensive industrial applications.
