Vinit Stainless, a well-known producer and supplier of premium stainless steel products with its headquarters located in Chennai, India, provides excellent and accurate services to a variety of industrial sectors. Stainless Steel 422 Nuts are one of our specialty products; they are made to provide exceptional strength, durability, and corrosion resistance. These high-end fasteners are designed to function well in high-temperature, high-stress settings, guaranteeing dependable fastening solutions for a variety of demanding applications. Vinit Stainless is dedicated to quality, prompt delivery, and client satisfaction. We are pleased to supply reliable stainless steel components to industries such as industrial manufacturing, power generation, automotive, and aerospace.
Stainless Steel 422 Nuts are crafted from a martensitic stainless steel alloy containing approximately 12.5% chromium, 1% molybdenum, 0.23% carbon, and 1% tungsten, with additions of nickel for enhanced strength and toughness. These nuts are heat-treatable and deliver high tensile strength (up to 895 MPa) and good creep resistance at elevated temperatures. Their balanced mechanical properties make them highly resistant to oxidation and deformation under load. With moderate corrosion resistance and excellent thermal stability, 422 nuts are ideal for components exposed to high stress, heat, and dynamic mechanical forces.
