Samuel Steels stands out as a top manufacturer and supplier of Alloy Steel F11 Bars in Abuja, Nigeria. We specialize in delivering high-quality chromium-molybdenum (Cr-Mo) alloy steel bars designed for high-pressure and high-temperature applications. Known for their exceptional strength, durability, and resistance to heat, oxidation, and corrosion, our Alloy Steel F11 Bars are meticulously crafted to meet ASTM A182 standards. They find extensive use in refineries, power plants, and the petrochemical and chemical industries. At Samuel Steels, we prioritize consistent mechanical performance, precise dimensions, and a flawless surface finish, making our F11 Bars perfect for tough industrial settings that demand reliability and toughness.
Alloy Steel F11 Bars generally consist of carbon (0.05–0.15%), manganese (0.30–0.60%), silicon (0.50% max), chromium (1.00–1.50%), molybdenum (0.44–0.65%), phosphorus (0.025% max), and sulfur (0.025% max), with iron making up the rest. These bars showcase impressive tensile strength ranging from 415 to 585 MPa, a yield strength of about 205 MPa, and an elongation of roughly 20%. They are known for their excellent toughness, creep resistance, and stability under thermal stress. The Cr-Mo alloy composition boosts hardness and oxidation resistance, ensuring reliable performance in high-temperature and high-pressure scenarios.
