Based in Kolkata, India, Aditya Stainless is a well-known producer and supplier of high-end stainless steel goods. Our specialty is providing a broad range of stainless steel parts, such as the incredibly dependable and long-lasting Stainless Steel 420 Nuts. These nuts are used in a variety of industries, including the automotive, aerospace, and marine sectors, due to their remarkable strength, hardness, and moderate resistance to corrosion. Aditya Stainless provides customized stainless steel solutions that are suited to the particular requirements of every project and application. We are dedicated to precision engineering, on-time delivery, and customer satisfaction.
The martensitic stainless steel alloy used to make Stainless Steel 420 Nuts is made up of 12–14% chromium, 0.15–0.40% carbon, and trace amounts of silicon, manganese, and other elements. This composition offers moderate corrosion resistance along with remarkable hardness and wear resistance. Their mechanical qualities are improved by heat treatment, which produces remarkable edge retention and dimensional stability in addition to tensile strengths of 700–850 MPa and yield strengths of about 345 MPa. Because of these qualities, 420 nuts are perfect for high-stress situations where durability, strength, and dependability are essential.
