Chung Metal provides Alloy Steel F11 Bars and Rods for high-temperature and high-stress applications in industry and power sectors. F11 is designed to exhibit enhanced creep strength, dimensional stability, and thermal-fatigue resistance. We produce F11 rods with strict chemistry and heat treatment control, and deliver validated mechanical properties and guarantee in quality. Customers in petrochemical, boiler, and turbine industries choose our F11 bars to be used in structure, piping, and headers. With finished sizes and customization, Chung Metal makes it easy for F11 pieces to be incorporated into fabrication processes.
F11 Alloy Steel normally contains chromium, molybdenum, and minor additions (e.g., vanadium or tungsten). Tensile strength can be ~650–800 MPa, yield strength ~400–550 MPa, elongation ~12–20%. Upon tempering, it possesses high hardness as well as good creep resistance. The alloy is thermally stable under elevated temperature service, with good fatigue strength and average toughness. Weldability can be realized through proper heat treatment and pre/post-weld procedures. The alloy is intermediate between less complex steels and more advanced creep steels.

Alloy Steel F11 Bars and Rods are commonly used in power generation, petrochemical, oil and gas, and chemical processing industries for high-temperature applications.
They offer excellent resistance to thermal fatigue, high strength, and outstanding performance in high-pressure and high-temperature environments.
F11 Bars/Rods are employed in superheater and reheater tubing parts, steam piping, boiler headers, and structural supports in thermal power plant conditions. Employed in heat exchangers and high-temperature process vessels in petrochemical plants as well. Parts undergoing thermal stress and moderate creep loading utilize F11 to achieve performance-cost balance. F11 is utilized where operating temperatures are not extreme but moderate, and the basic steels would suffer in the long run. It provides greater service life in furnaces, piping systems, and equipment in process industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
