Aditya Stainless, based in Kolkata, India, stands out as a leading manufacturer and supplier of Stainless Steel 440C Bolts. These bolts are specifically designed for applications that demand outstanding hardness, wear resistance, and protection against corrosion. Crafted from high-carbon martensitic stainless steel, they are precision-engineered to deliver maximum strength and durability, even in the toughest mechanical and environmental conditions. Aditya Stainless ensures that their bolts meet international quality standards, providing dimensional accuracy, an excellent surface finish, and reliable performance. Our 440C bolts are perfect for industries like aerospace, defense, automotive, tooling, and high-precision engineering, where both strength and corrosion resistance are crucial.
Stainless Steel 440C Bolts are made with a high carbon content (0.95–1.20%), chromium (16–18%), and very little nickel. This unique blend gives them impressive hardness and great corrosion resistance in mild environments. After undergoing heat treatment, 440C can reach a tensile strength of up to 760–980 MPa and a Rockwell hardness of 58–60 HRC. These bolts also boast excellent dimensional stability, superior wear resistance, and moderate toughness. They are perfect for applications that require high strength and abrasion resistance, merging mechanical performance with the corrosion-resistant qualities of stainless steel.
