Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for delivering top-notch Stainless Steel 409 Bolts. These bolts are celebrated for their impressive durability, weldability, and resistance to oxidation. Crafted from ferritic stainless steel, they excel in high-temperature environments while providing decent corrosion resistance. Designed for demanding industrial and structural applications, Stainless Steel 409 Bolts are essential for situations where heat stability and reliability are crucial. Thanks to advanced production methods and strict quality control, Lecong Stainless guarantees that its bolts meet international standards, catering to industries throughout Vietnam and beyond with precision.
These bolts are made up of iron, chromium (10.5–11.75%), low carbon, manganese, and silicon, with titanium often included for added stability. This unique blend enhances their weldability, toughness, and resistance to scaling at high temperatures. Their mechanical properties boast a tensile strength of 380–450 MPa, yield strength of 170–240 MPa, and good elongation, making them ideal for secure fastening under stress. The ferritic structure ensures thermal stability, dimensional accuracy, and moderate corrosion resistance. While they may not match the resistance of austenitic grades, Stainless Steel 409 Bolts offer a great balance between cost and performance, making them a dependable choice for high-temperature applications.
