Neil Metals stands out as a top-notch manufacturer and supplier of high-quality Alloy Steel F91 Bars and Rods, proudly based in Kolkata, India. Known for its commitment to precision engineering and strict adherence to international standards, Neil Metals provides durable and high-performance alloy steel products that cater to the needs of demanding industries. The company specializes in crafting F91 grade bars and rods, which are celebrated for their remarkable strength, high-temperature resistance, and corrosion-resistant features. With a team of skilled professionals and state-of-the-art manufacturing facilities, Neil Metals guarantees consistent quality and timely delivery to clients both in India and around the globe.
Alloy Steel F91 Bars and Rods are primarily made up of chromium (8–9.5%) and molybdenum (0.85–1.05%), along with trace amounts of vanadium, carbon, manganese, phosphorus, sulfur, and silicon. These elements work together to boost the alloy’s hardness, strength, and resistance to heat and corrosion. On the mechanical side, F91 boasts impressive tensile strength (minimum 585 MPa), yield strength (minimum 415 MPa), and good elongation (minimum 20%), making it perfect for high-stress environments. The blend of these mechanical and chemical properties ensures that it performs reliably in demanding applications.
