Luke Steel is a prominent manufacturer and distributor of Alloy Steel F12 Flanges in Houston, USA. The organization has a comprehensive assortment of F12 flanges that are well designed to achieve ASTM A182 standards and have steadfast performance in high-temperature and high-pressure applications. The flanges come in several types, such as weld neck, slip-on, blind, socket weld, and threaded flanges, and have different sizes and pressure classes. Luke Steel’s dedication to quality, precision machining, and on-time delivery has gained the confidence of sectors including oil & gas, power generation, chemical processing, and petrochemicals throughout the United States and overseas.
Alloy Steel F12 Flanges consist of a chromium-molybdenum steel alloy having about 1.0–1.5% chromium, 0.44–0.65% molybdenum, and ≤0.15% carbon, and trace amounts of manganese, silicon, and iron. This makes them display superb thermal stability, corrosion resistance, and high strength at higher temperatures. The mechanical properties are tensile strength of 415–585 MPa, yield strength of ≥205 MPa, and 20% minimum elongation. F12 flanges exhibit adequate weldability, toughness, and fatigue strength and hence find applications in both tempered or annealed and normalized conditions for high-pressure piping systems.
