Luke Steel is a reliable Alloy Steel Fastener manufacturer and supplier located in Houston, USA. Committed to quality, accuracy, and performance, the company supplies an extensive variety of alloy steel fasteners such as bolts, nuts, washers, screws, and studs. These fasteners are reputed for their high tensile strength, resistance to wear, pressure, and heat. Luke Steel distributes to markets like oil & gas, automotive, power generation, construction, and petrochemical. Supported by sophisticated manufacturing processes and rigorous quality checking, Luke Steel provides timely delivery and adherence to international standards such as ASTM and ASME.
Alloy Steel Fasteners may also have chromium (0.80–1.10%), molybdenum (0.15–0.25%), carbon (0.38–0.43%), manganese, and iron. The alloying factors improve hardness, tensile strength, and corrosion resistance. Mechanical properties are tensile strength up to 860 MPa, yield strength of about 415–655 MPa, and superb fatigue and impact resistance. They are good for machinability and can be heat-treated to enhance hardness and performance under key applications and thus prove stable under high stress and temperature conditions.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Alloy Steel Fasteners have universal application in high-strength and high-temperature conditions. Major industries where they are used include oil refineries, petrochemical plants, power plants, pressure vessels, heavy machinery, and car engines. They hold structural parts that are subject to stress, vibrations, and heat, including flanges, turbines, engine blocks, exhaust systems, and compressors. In the aerospace and defense industries, they are employed in load-critical joints where strength and resistance against fatigue are critical. Their heat treatment and surface coating versatility also qualifies them for corrosive and outdoor applications, providing lasting performance in static and dynamic uses.
