Veer Flanges is a reputable manufacturer and supplier of Low Temperature Carbon Steel LF5 Flanges based in Kolkata, India. They cater to the increasing needs of industries that operate in cold and cryogenic settings. Crafted in line with ASTM A350 standards, LF5 flanges are engineered to provide outstanding mechanical strength, notch toughness, and durability even at low to extremely low temperatures. With a commitment to quality, reliability, and precise dimensions, Veer Flanges offers LF5 flanges in various styles, including weld neck, slip-on, blind, and threaded. These flanges are perfect for applications in LNG plants, petrochemical sectors, and gas processing facilities.
LF5 is a low-temperature carbon steel known for its superior mechanical properties. It typically contains carbon (≤0.30%), manganese (0.60–1.35%), nickel (up to 1.00%), phosphorus (≤0.035%), and sulfur (≤0.040%). This specific composition enhances ductility and impact resistance at temperatures ranging from -50°C to -101°C. LF5 flanges boast a tensile strength of 485–655 MPa and a yield strength of at least 250 MPa, often being normalized or quenched and tempered. They strike a perfect balance between strength, toughness, and corrosion resistance, making them ideal for challenging low-temperature applications.
