Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 347H Bolts. These bolts are crafted for outstanding durability, corrosion resistance, and performance at high temperatures. Stainless Steel 347H is a titanium-stabilized austenitic stainless steel that boasts a higher carbon content, which enhances its creep strength and resistance to intergranular corrosion, especially when exposed to elevated temperatures for extended periods. Each bolt is precision-engineered to meet international standards, ensuring they are reliable for fastening applications in sectors like power generation, petrochemical, chemical, and various industrial fields where strength and stability are crucial.
The composition of Stainless Steel 347H Bolts includes iron, chromium (17–19%), nickel (9–13%), and titanium for stabilization, along with manganese, silicon, and a higher carbon content to boost strength. The titanium stabilization helps prevent carbide precipitation during welding, which is key for long-lasting corrosion resistance. These bolts exhibit impressive mechanical properties, with a tensile strength ranging from 515 to 750 MPa and a yield strength between 205 and 275 MPa, along with excellent creep and oxidation resistance at temperatures reaching up to 700°C. Their austenitic microstructure guarantees toughness, dimensional stability, and reliability even in demanding operating conditions.
