Luke Steel, based in Houston, Houstan, is a reliable manufacturer and supplier of Alloy Steel F12 Forged Fittings, designed for high-temperature and moderate-pressure settings. These fittings are made from high-quality chromium-molybdenum alloy, ensuring long-lasting performance in thermal and fluid systems. F12 provides excellent oxidation resistance and moderate creep strength, making it suitable for the power, chemical, and refinery industries. With precise forging techniques and strict quality checks, Luke Steel guarantees dimensional accuracy and mechanical strength in each fitting, ensuring performance and safety where it matters most in industrial piping and pressure vessel applications.
Alloy Steel F12 includes 1% molybdenum and 2.25% chromium, offering strength and great oxidation resistance. These fittings generally have a tensile strength of 690 to 740 MPa, a yield strength of around 410 MPa, and elongation of 18 to 20%. The alloy stays structurally stable up to 575°C. F12 forged fittings provide moderate creep resistance, good weldability, and resistance to scale buildup at high temperatures. Heat treatment such as normalization and tempering further improves their mechanical performance. The material is perfect for pressure and heat-intensive settings that require stable long-term operation without material breakdown.

Alloy Steel F12 Forged Fittings are commonly found in boiler parts, superheaters, and high-pressure piping systems. These fittings are ideal for power plants, refineries, and chemical industries where thermal expansion, high temperatures, and oxidative gases exist. They connect critical pipe systems, like elbows, tees, couplings, and unions, that undergo constant thermal cycling. F12’s metallurgical structure provides stability under stress, minimizing leakage and extending system life. Luke Steel provides ASME- and ASTM-compliant F12 forged fittings tailored to specific industrial needs, ensuring safe, leak-proof connections in complex piping networks exposed to harsh conditions.
