Luke Steel is a top-notch manufacturer and supplier located in Houston, Houstan, specializing in high-quality Alloy Steel Gr B16 Bolts designed for demanding industrial applications. We pride ourselves on our commitment to strength, durability, and reliability, ensuring our bolts meet rigorous international standards like ASTM A193 Grade B16. These bolts are engineered to thrive in high-pressure and high-temperature settings, making them perfect for critical roles in the power, petrochemical, oil & gas, and refinery industries. At Luke Steel, we blend cutting-edge manufacturing technology with strict quality control to provide Alloy Steel B16 bolts that guarantee secure and long-lasting fastening, even in the toughest conditions.
Our Alloy Steel Gr B16 Bolts are crafted from chromium-molybdenum-vanadium steel, featuring a typical composition that includes carbon (0.40–0.50%), manganese (0.75–1.00%), phosphorus (max 0.035%), sulfur (max 0.040%), silicon (0.15–0.35%), chromium (0.70–0.90%), molybdenum (0.40–0.60%), and vanadium (0.20–0.30%). These bolts boast a minimum tensile strength of 860 MPa and a yield strength of 690 MPa. Renowned for their exceptional strength, heat resistance, and creep resistance, B16 bolts are often heat-treated (quenched and tempered) to boost their mechanical performance under high temperatures and pressures, making them ideal for severe operating conditions.
