Luke Steel is proud to manufacture and supply Alloy Steel B7 Stud Bolts right here in Houston, USA. These fasteners are designed for industries that demand strength and reliability in high-pressure, high-temperature settings. Crafted from chromium-molybdenum steel, B7 bolts are renowned for their remarkable strength, impressive heat resistance, and corrosion protection. You’ll often find these stud bolts in power plants, refineries, and petrochemical facilities where pressure and temperature fluctuations are a regular occurrence. At Luke Steel, we ensure our B7 stud bolts meet rigorous international standards, delivering top-notch performance, durability, and quality for critical applications that require secure, long-lasting bolting solutions.
Alloy Steel B7 Stud Bolts are made up of 0.35% carbon, 1.25% chromium, and 0.5% molybdenum, which gives them high tensile strength and excellent oxidation resistance. They boast a tensile strength ranging from 900 to 1100 MPa, a yield strength of about 600 MPa, and an elongation of 12 to 14%. Designed to withstand temperatures up to 600°C, these bolts maintain their structural integrity even under thermal and mechanical stress. The enhanced properties of the alloy make these bolts resistant to thermal fatigue, creep, and corrosion, making them perfect for demanding applications in power plants and chemical processing industries.
