Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for its high-quality Stainless Steel 409 Stud Bolts. These bolts are celebrated for their strength, durability, and affordability. Crafted from ferritic stainless steel, they boast impressive oxidation and corrosion resistance, excellent weldability, and thermal stability. Specifically designed for fastening in environments that experience heat and moderate corrosion, these stud bolts are a reliable choice. With state-of-the-art manufacturing facilities and rigorous quality control, Lecong Stainless guarantees that its Stainless Steel 409 Stud Bolts adhere to international standards, catering to both local industries in Vietnam and global markets with dependable fastening solutions.
The composition of Stainless Steel 409 Stud Bolts primarily includes iron, chromium (10.5–11.75%), manganese, silicon, and low carbon, with titanium sometimes added for stabilization. This blend offers moderate corrosion resistance and enhances scaling resistance at high temperatures. Their mechanical properties feature a tensile strength ranging from 380 to 450 MPa, yield strength between 170 and 240 MPa, and good elongation, making them ideal for long-lasting fastening. The ferritic structure contributes to their thermal stability and oxidation resistance, while the low carbon content promotes good weldability and minimizes the risk of carbide precipitation. These characteristics make Stainless Steel 409 Stud Bolts both practical and cost-effective for industrial applications.
