Luke Steel, located in Houston, Houstan, is a trusted manufacturer and supplier of Alloy Steel F2 Bars. These bars are designed for moderate to high-temperature industrial applications. Known for their strength and mild corrosion resistance, F2 Bars perform reliably in steam and pressure vessel settings. They are made for durability in medium-temperature operations while maintaining great machinability and toughness. With a commitment to quality and on-time delivery, Luke Steel supports engineers and manufacturers across the energy, processing, and mechanical sectors by providing top-grade Alloy Steel F2 Bars that meet high performance and safety standards.
Alloy Steel F2 Bars mainly consist of carbon, manganese, chromium (up to 1.5%), and molybdenum, providing a good mix of strength and ductility. They deliver a tensile strength of 620–690 MPa, yield strength of around 380 MPa, and an elongation of 20–25%. With decent resistance to thermal fatigue and moderate corrosion, F2 performs well at service temperatures up to 540°C. The alloy offers fair weldability and excellent mechanical stability during thermal and pressure cycles, making it suitable for mid-grade heat service conditions.
