Rupal Metals is a reputable manufacturer and supplier located in Delhi, India, specializing in high-quality Carbon Steel A350 LF2 Bars and Rods designed for applications in low-temperature and pressure systems. This low-alloy carbon steel, known as ASTM A350 LF2, boasts impressive toughness, weldability, and strength even in sub-zero conditions. At Rupal Metals, we employ cutting-edge manufacturing techniques and strict quality control measures to ensure our bars and rods meet international standards for mechanical reliability and precision. Our A350 LF2 products are commonly found in petrochemical plants, refineries, power generation systems, and various other industries that demand reliable performance in cold environments.
Carbon Steel A350 LF2 is a low-alloy steel primarily made up of Carbon (up to 0.3%), Manganese (0.6–1.35%), along with trace amounts of Phosphorus, Sulfur, Silicon, and occasionally Nickel. It offers a well-rounded mix of strength and toughness, making it particularly suitable for low-temperature applications. Typical mechanical properties include a tensile strength ranging from 485 to 655 MPa, a yield strength of at least 250 MPa, and impressive impact resistance at -46°C (Charpy V-Notch). This alloy is not only easy to machine and weld but also responds well to normalization and tempering, enhancing its strength, ductility, and resistance to brittle fracture in cold conditions.
