Based in Chennai, India, Vinit Stainless is a top producer and supplier of 422 stainless steel bolts, providing high-end fastening solutions designed for high-stress and high-temperature settings. We offer bolts with exceptional mechanical performance and oxidation resistance, and we are well-known for our dedication to quality, accuracy, and client satisfaction. Our SS 422 bolts are produced in accordance with international standards by utilising premium raw materials and cutting-edge manufacturing processes. Perfect for heavy engineering, power generation, and aerospace, Vinit Stainless provides customers in India and abroad with dependable, high-strength bolts that are supported by prompt delivery and affordable prices.
Approximately 12% chromium, 0.20–0.25% carbon, and additions of molybdenum, tungsten, and vanadium make up the martensitic stainless steel alloy used to make Stainless Steel 422 Bolts. Strength, hardness, and high-temperature performance are all improved by these components. SS 422 has exceptional mechanical qualities, such as a yield strength of about 650 MPa following heat treatment and a tensile strength of up to 1000 MPa. Up to 650°C, the bolts continue to exhibit good resistance to oxidation and creep. They are appropriate for applications needing durability under mechanical and thermal stress because of their hardness and fatigue strength.
