Shriram Metal is an established supplier and exporter of high-quality Stainless Steel 321/321H Sheets, Plates, and Coils, which are noted for their superior resistance to oxidation and corrosion at high temperatures. Stainless Steel 321 is a titanium-stabilized austenitic stainless steel with improved resistance to intergranular corrosion, making it appropriate for applications that need extended exposure to high temperatures. SS 321H, on the other hand, has a greater carbon content, which improves high-temperature strength, making it appropriate for heat-intensive sectors such as petrochemical, aerospace, and power generation. Our ASTM A240 SS 321 Sheets and Plates are used in thermal processing, furnace components, and exhaust systems because of their exceptional mechanical qualities and endurance.
At Shriram Metal, we provide SS 321/321H Coils in wide range of finishes and thicknesses to satisfy the different needs of our clients across industries.
