Luke Steel is a well-respected manufacturer and supplier of Alloy Steel Grade B16 fasteners, proudly based in Houston, USA. They specialize in providing high-strength, high-performance fastening solutions for various industries, including oil & gas, power generation, petrochemical, and heavy machinery. The company offers a diverse range of fasteners, such as bolts, nuts, studs, and washers, all crafted to meet the ASTM A193 Grade B16 standards. With cutting-edge production technology, rigorous quality control, and a commitment to customer satisfaction, Luke Steel ensures that their fasteners are reliable, corrosion-resistant, and built to perform under high-pressure, high-temperature, and corrosive conditions.
Alloy Steel Grade B16 fasteners are made up of chromium (0.80–1.10%), molybdenum (0.40–0.65%), and carbon (0.36–0.44%), with carefully controlled amounts of manganese, silicon, phosphorus, and sulfur. This specific alloy steel grade is engineered for high-pressure, high-temperature applications. Typically, these fasteners boast mechanical properties like a minimum tensile strength of 800 MPa, a minimum yield strength of 620 MPa, and an elongation of at least 16%. Grade B16 fasteners are known for their exceptional strength, hardness, and creep resistance, along with solid fatigue performance, making them perfect for critical and demanding industrial uses.
