Luke Steel, Houston‘s trusted industrial fastener manufacturer, provides Alloy Steel Grade 6 Screws for high-load and elevated-temperature use. Produced to ASTM specifications, these screws have strength coupled with creep and stress relaxation resistance, and they are applicable to severe assemblies in heavy engineering industries. Luke Steel ensures quality consistency, traceability of heat treatment, and material certification.
Grade 6 screws are Chrome (~1.2%), Molybdenum (~0.4%), and Carbon (~0.2%) alloyed. These improve strength, hardness, and resistance to heat. The screws have yield strengths of approximately 620–680 MPa and tensile strength 720–820 MPa, and the screws perform superbly at high temperatures. They retain dimensional stability under cyclic loading.
