We at Pratik Pipe & Fittings proudly manufacture and supply high-quality Stainless Steel 321 Sheets in Mumbai, India. All our items have been designed with a view to satisfying the high performance and high requirements of many industries with high performance and durability. Stainless Steel 321 is a titanium-stabilized stainless steel with an austenitic structure, famous for its high intergranular corrosion resistance, particularly following long-term service at high temperatures between 427-816°C.
With 17-19% chromium, 9-12% nickel, and a minor titanium proportion, the alloy is specifically designed to resist extreme temperatures and environments with no loss of its form. Our Sheets comply with ASTM A312 and ASME SA312 specifications, providing international compliance with standards. For customers with a demand for DIN compliance, we have EN 1.4541 tubing for them to opt for.
One of the key benefits of Stainless Steel 321 Sheets is its increased oxidation and intergranular corrosion resistance, courtesy of its titanium stabilization. With this, it is best for use in processes with long-term high temperature exposure, including in heat exchangers, exhausts, and pressure vessels. With its capacity to maintain its structure even at temperatures of 900°C, its performance and durability can extend for a long period of time.
The versatility of Stainless Steel 321 Sheets make them an economically sound alternative for industries that require high temperature and corrosive resistant materials. With high temperature and corrosive resistant properties, and yet, with no loss of mechanical integrity and strength at extreme temperatures, make them a useful tool in many processes including automotive, chemical processing, and power generation.
