Aditya Stainless, a well-known manufacturer and supplier located in Kolkata, India, focuses on producing top-notch Stainless Steel 446 Bolts designed to withstand extreme temperatures and harsh corrosive environments. These bolts are celebrated for their impressive resistance to oxidation, sulfidation, and scaling, making them perfect for tough industrial applications. Crafted to meet strict international standards, Aditya Stainless guarantees precision machining, a superb surface finish, and accurate dimensions. Catering to a diverse array of industries such as petrochemical, thermal processing, furnace equipment, and power plants, the company has built a reputation for providing durable and dependable fastening solutions both locally and globally.
Stainless Steel 446 Bolts are crafted from a ferritic, non-heat treatable stainless steel that contains chromium (23–27%), low carbon (≤0.20%), and trace amounts of molybdenum, silicon, and nickel. These bolts showcase outstanding oxidation and corrosion resistance, especially in sulfur-rich environments. Their mechanical properties include a tensile strength ranging from 485–620 MPa, a yield strength of about 275 MPa, and an elongation of 20–30%. While they may not be as strong as austenitic grades, 446 bolts provide excellent thermal stability and can resist scaling up to 1100°C, making them a reliable choice for high-temperature fastening needs.
