Sterlite Metal Industries is a prominent manufacturer, stockist, and exporter of Stainless Steel 321 and 321H pipes and tubes, catering to various industries worldwide. Stainless Steel 321 and 321H are high-performance alloys that are widely appreciated for their exceptional resistance to high-temperature oxidation and intergranular corrosion. These alloys contain titanium, which stabilizes the material against carbide precipitation and ensures long-lasting durability. Stainless Steel 321H, with its higher carbon content, is specially designed to withstand even more extreme temperature conditions, making it ideal for applications that require enhanced strength at elevated temperatures. Sterlite Metal Industries offers these pipes and tubes in a range of sizes, finishes, and specifications to meet the diverse needs of industries such as petrochemical, power generation, aerospace, and marine.

Stainless Steel 321 is widely used in applications where elevated temperature resistance is required, including exhaust systems, heat exchangers, and boiler components. The alloy’s excellent weldability and resistance to oxidation make it a popular choice for industries dealing with heat-induced stresses, such as the power and chemical sectors. On the other hand, Stainless Steel 321H, with its higher carbon content, provides even greater strength and is used in applications involving higher thermal stresses and temperatures, such as in the petrochemical industry and aerospace sector. Both grades offer excellent resistance to corrosion in highly acidic environments, making them suitable for a variety of harsh applications.

Sterlite Metal Industries exports Stainless Steel 321 and 321H pipes and tubes to numerous countries, including Oman, Qatar, Kuwait, UAE, Saudi Arabia, Spain, Japan, the United States, the United Kingdom, and Ireland.
