With a reputation for consistent quality, technical know-how, and prompt delivery, Sadiki Metals is a reliable source for premium Alloy Steel F91 Bars and Rods.
Alloy Steel F91 is a high-chromium, molybdenum steel that contains about 0.08–0.12% carbon, 8–9% chromium, 0.85–1.05% molybdenum, and 0.2% vanadium, along with trace elements of manganese, silicon, and nickel. This unique blend gives it remarkable high-temperature strength, creep resistance, and toughness. Typical mechanical properties feature a tensile strength ranging from 750–900 MPa, yield strength between 500–650 MPa, and elongation of 12–20%. F91 steel is amenable to heat treatment and tempering, providing excellent fatigue and corrosion resistance, making it perfect for demanding high-temperature and high-stress applications.
