Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for its high-quality Stainless Steel 405 Nuts that are built for strength, durability, and heat resistance. This type of stainless steel, which is ferritic and stabilized with aluminum, boasts excellent oxidation resistance and improved weldability, while also preventing hardening during heat treatment. As a result, Stainless Steel 405 Nuts are perfect for fastening solutions in high-temperature settings and moderately corrosive environments. With state-of-the-art production facilities and rigorous quality checks, Lecong Stainless guarantees that its Stainless Steel 405 Nuts adhere to international standards, catering to industries throughout Vietnam and beyond with dependable performance and a long lifespan.
These nuts are made from a blend of iron, chromium (11.5–14.5%), aluminum (for stabilization), low carbon, manganese, and silicon. The addition of aluminum not only enhances weldability but also reduces carbide precipitation and ensures resistance to scaling at high temperatures. Their mechanical properties include a tensile strength ranging from 380 to 540 MPa, yield strength between 170 and 240 MPa, and good ductility, which allows for secure fastening even under stress. Thanks to their ferritic structure, they offer dimensional stability, toughness, and moderate corrosion resistance, making them suitable for both structural and industrial applications. Stainless Steel 405 Nuts are a cost-effective fastening solution where durability, heat resistance, and strength are key.
