Neil Metals, based in Kolkata, India, stands out as a top manufacturer and supplier of high-performance Alloy Steel F12 Bars and Rods. These products are celebrated for their remarkable mechanical strength, thermal stability, and resistance to corrosion. Built to endure high-pressure and high-temperature conditions, these bars and rods are crafted to comply with global quality standards. Neil Metals prides itself on offering tailored dimensions, prompt deliveries, and unwavering quality, catering to vital sectors like power generation, petrochemicals, refineries, and energy infrastructure. With a strong commitment to durability and customer satisfaction, Neil Metals has earned a reputation as a reliable provider of alloy steel solutions both domestically and internationally.
Alloy Steel F12 Bars and Rods mainly consist of 0.05–0.15% carbon, 0.30–0.60% manganese, 0.44–0.65% molybdenum, and 0.80–1.25% chromium, with the remainder being iron and trace elements. These alloying components contribute to excellent high-temperature strength, oxidation resistance, and good hardenability. F12 bars boast a tensile strength of about 485–620 MPa and a yield strength of roughly 275–415 MPa. They are suitable for heat treatment and maintain their structural integrity under thermal and mechanical stress, making them perfect for applications in pressure vessels, boilers, and high-temperature piping systems.
