Based in Chennai, India, Vinit Stainless is a well-known producer and supplier of high-end stainless steel goods. Stainless Steel 321H Nuts are one of our specialty products; they are designed to perform exceptionally well in corrosive and high-temperature conditions. These nuts have exceptional mechanical strength, thermal stability, and resistance to oxidation because they are made of premium 321H stainless steel. Vinit Stainless upholds strict quality standards to guarantee that each product satisfies the exacting specifications of sectors like aerospace, construction, and petrochemicals. We offer solutions that support high-performance operations in crucial applications, with an emphasis on accuracy, dependability, and prompt delivery.
The austenitic stainless steel alloy used to make Stainless Steel 321H Nuts contains roughly 17–19% Chromium, 9–12% Nickel, and Titanium. This alloy improves resistance to intergranular corrosion and stops carbide precipitation during welding. Compared to standard 321, the 321H grade has a higher carbon content, which increases its creep strength at higher temperatures. High tensile strength, durability, and thermal stability are just a few of these nuts’ exceptional mechanical qualities. They are ideal for applications involving extreme heat because of their resistance to oxidation and scaling at temperatures higher than 800°C (1472°F).
