Luke Steel is a reputable manufacturer and supplier located in Houston, Houstan, known for its high-performance Alloy Steel Valves designed for tough industrial flow control systems. These valves are crafted with precision from top-quality alloy steels, ensuring they deliver outstanding strength, pressure resistance, and durability even in high-temperature and corrosive settings. Luke Steel offers a wide variety of gate, globe, check, and ball valves, available in different pressure ratings and end connections. With a strong commitment to quality assurance, industry standards, and tailored solutions, Luke Steel caters to essential sectors such as oil & gas, petrochemical, power generation, and marine engineering.
Alloy Steel Valves are made from a blend of alloy steels that typically contain carbon (0.15–0.30%), chromium (1.00–2.00%), molybdenum (0.20–0.60%), along with manganese and vanadium, depending on the specific grade (like ASTM A182 F11, F22, F91). These components enhance the valves’ hardness, tensile strength, and resistance to corrosion and thermal stress. The tensile strength of alloy steel valves ranges from 415 to 860 MPa, with yield strength between 205 to 690 MPa, ensuring they perform reliably under high pressure and elevated temperatures. Techniques like normalizing, quenching, and tempering are employed to fine-tune their mechanical properties.
