Harshita Stainless, located in Delhi, India, stands out as a top manufacturer and supplier of premium Stainless Steel 321 Coils. Our coils are expertly designed to perform exceptionally well in high-temperature and corrosive settings, making them perfect for a variety of industrial uses. Renowned for their outstanding oxidation resistance and stability, our Stainless Steel 321 Coils adhere to strict quality standards and are built to endure thermal cycling without losing strength. Industries like aerospace, chemical, and automotive trust our coils for their reliable and durable solutions, tailored to meet the unique needs of today’s manufacturing landscape.
Stainless Steel 321 Coils are made up mainly of chromium (17-19%), nickel (9-13%), and titanium (0.7%), which helps prevent carbide precipitation and boosts resistance to intergranular corrosion. This alloy boasts impressive mechanical properties, featuring a tensile strength of around 75 ksi and good elongation of about 30%. The titanium stabilization enhances the coil’s performance at high temperatures, reaching up to 870°C, by preserving structural integrity and avoiding grain boundary weakening. Additionally, these coils exhibit excellent toughness and oxidation resistance, making them a dependable choice for demanding, heat-intensive industrial environments.
