Harshita Stainless, a reputable manufacturer and supplier located in Delhi, India, specializes in high-quality Stainless Steel 321 Nuts that are built to last and engineered for precision. Renowned for their outstanding corrosion resistance and stability at elevated temperatures, our 321 Nuts are meticulously crafted to adhere to strict industry standards. With a strong commitment to quality and customer satisfaction, Harshita Stainless guarantees that each nut performs exceptionally well in challenging environments. Our Stainless Steel 321 Nuts are extensively utilized across various industries, providing reliable fastening solutions that endure stress, oxidation, and temperature fluctuations. We take pride in our prompt delivery and consistent product quality.
Stainless Steel 321 Nuts are mainly made up of chromium (17-19%), nickel (9-12%), and titanium (0.7%), which helps stabilize the alloy and prevents carbide precipitation. This unique composition offers remarkable resistance to intergranular corrosion, particularly after being subjected to high temperatures. In terms of mechanical properties, these nuts demonstrate impressive tensile strength (around 75 ksi) and toughness, with a typical hardness range of 95-105 HRB. Their stability during thermal cycling and stress makes them perfect for environments with temperatures reaching up to 870°C, ensuring they remain reliable for critical fastening tasks.
