Lecong Stainless, a well-respected manufacturer and supplier based in Da Nang, Vietnam, specializes in high-performance Stainless Steel 422 Bolts. These bolts are crafted to provide outstanding strength, durability, and resistance to high temperatures. Stainless Steel 422 is a martensitic grade known for its impressive corrosion resistance and excellent mechanical properties, along with its ability to withstand oxidation in elevated temperatures. Our SS 422 Bolts are meticulously engineered with precise threading, a smooth finish, and dependable load-bearing capacity, ensuring safe and efficient fastening in critical applications. They are widely utilized in industries such as turbines, aerospace, automotive, and power generation, where they are relied upon for their remarkable performance in extreme conditions.
Stainless Steel 422 Bolts consist of 12% chromium, 1% molybdenum, and 1% tungsten, along with carefully controlled amounts of carbon, silicon, manganese, and nickel. This unique blend gives them high strength, oxidation resistance, and wear resistance, particularly at elevated temperatures. In terms of mechanical properties, SS 422 Bolts boast a tensile strength of up to 930 MPa and a yield strength of around 620 MPa, along with excellent creep-rupture resistance. They maintain their stability and toughness even under thermal cycling and mechanical stress, making them perfect for high-temperature applications. Additionally, these bolts are heat-treatable, which boosts their hardness and durability while still offering moderate corrosion resistance.
