Liam Steel is a reputable manufacturer and supplier located in Manila, Philippines, focusing on Low Temperature Carbon Steel A420 WPL8 Pipe Fittings. With a strong dedication to quality, precision engineering, and customer satisfaction, Liam Steel delivers dependable fittings that adhere to international standards like ASTM and ASME. These pipe fittings are crafted to perform effectively in low-temperature settings, ensuring robust strength and leak-proof connections. Thanks to cutting-edge manufacturing technology and rigorous quality control, Liam Steel has built a solid reputation for providing durable and cost-efficient piping solutions for sectors such as petrochemical, oil & gas, power generation, and shipbuilding.
Low Temperature Carbon Steel A420 WPL8 Pipe Fittings are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon. The typical makeup includes a maximum of 0.30% carbon, 0.90–1.65% manganese, 0.035% maximum phosphorus, and 0.040% maximum sulfur. These fittings showcase remarkable impact toughness and ductility, even in sub-zero temperatures. Mechanically, they have a minimum tensile strength of 415 MPa and a minimum yield strength of 240 MPa, along with good elongation properties. This blend of strength, toughness, and weldability makes A420 WPL8 perfect for low-temperature applications.
