Samuel Steels is a reliable manufacturer and supplier of Alloy Steel F12 Bars based in Abuja, Nigeria. We provide top-notch alloy steel products designed for high-temperature and high-pressure applications. Alloy Steel F12, a chromium-molybdenum (Cr-Mo) low-alloy steel, is celebrated for its remarkable mechanical strength, toughness, and resistance to corrosion, oxidation, and creep at elevated temperatures. Our bars are crafted with precision, strictly following ASTM A182 standards to ensure they perform reliably in demanding industrial settings. Samuel Steels supplies F12 Bars to various sectors, including oil and gas, power generation, petrochemical, and refineries, where durability and performance under stress are essential.
Alloy Steel F12 Bars generally consist of carbon (0.05–0.20%), manganese (0.30–0.60%), silicon (0.50% max), chromium (0.80–1.25%), molybdenum (0.44–0.65%), phosphorus (0.025% max), and sulfur (0.025% max), with iron making up the remainder. These bars boast a tensile strength ranging from 415 to 585 MPa and a yield strength of about 205 MPa, along with an elongation of 20%. They are known for their excellent toughness, weldability, and heat resistance. The Cr-Mo combination enhances creep strength and thermal stability, ensuring that F12 Bars maintain their mechanical integrity even when exposed to high temperatures and pressures for extended periods.
