Luke Steel is a well-known Alloy Steel F12 Bars manufacturer and supplier in Houston, USA. The company is renowned for offering high-performance alloy steel products and supplying F12 bars that conform to ASTM A182 specifications and are used in high-temperature and high-pressure applications. The bars are offered in different sizes, finishes, and custom lengths as per industrial requirements. With a strong emphasis on quality and timely delivery, Luke Steel ensures that each F12 bar provides superior strength, corrosion resistance, and machinability. Businesses across oil & gas, power plants, refineries, and petrochemicals count on Luke Steel for reliable F12 alloy steel solutions.
Alloy Steel F12 Bars are low-alloy steels that contain chromium (1.0ā1.5%), molybdenum (0.44ā0.65%), carbon (ā¤0.15%), manganese, silicon, and iron. These components possess superior oxidation, scaling, and high-temperature creep resistance. Mechanical characteristics are tensile strength of 415ā585 MPa, yield strength of ā„205 MPa, and elongation of 20% minimum. F12 bars possess good weldability, toughness, and are resistant to thermal and mechanical stress, and thus are best suited for heat-treated or normalized conditions.
