Alloy Steel Gr B6 Bolts are crafted from a robust chromium-molybdenum alloy steel, primarily made up of iron, with a composition that includes 11-13% chromium along with small amounts of carbon, manganese, silicon, and phosphorus. This unique blend not only boosts corrosion resistance but also enhances mechanical strength and stability when exposed to high temperatures. These bolts boast a minimum tensile strength of 515 MPa and a yield strength of at least 205 MPa, showcasing impressive hardness and ductility. Thanks to these mechanical properties, they are perfect for high-pressure and high-temperature applications, where wear resistance, oxidation prevention, and thermal stress management are crucial for long-lasting performance and structural integrity.
Industries that require high strength and corrosion resistance in tough conditions extensively use Alloy Steel Gr B6 Bolts. They’re commonly found in power generation, oil and gas processing, chemical plants, and the petrochemical sector. These bolts play a vital role in assembling pressure vessels, heat exchangers, boilers, and high-temperature piping systems. Their toughness and ability to resist scaling at elevated temperatures make them ideal for marine, automotive, and aerospace applications. In critical situations where durability and safety are paramount, Alloy Steel Gr B6 Bolts consistently deliver reliable performance and a long service life.
