Luke Steel is a reliable manufacturer and supplier of Low Temperature Carbon Steel A420 WPL9 Pipe Fittings, with headquarters proudly based in Houstan, USA. We offer high-performance fittings designed to function well in low-temperature conditions while adhering to international quality standards. Supported by accurate manufacturing, technical know-how, and on-time delivery commitments, we serve the stringent requirements of industries like oil & gas, petrochemicals, and cryogenics. In line with its emphasis on affordable and tailored solutions, Luke Steel is known for providing reliable pipe fittings that guarantee safe operation in freezing conditions within the USA and internationally.
Pipe fittings A420 WPL9 are made of carbon, manganese, phosphorus, sulfur, and molybdenum to provide strength and ductility when used in below-zero applications. These fittings provide a tensile strength of 415–585 MPa and a minimum yield strength of 205 MPa, as well as superior impact toughness at low temperatures. The microstructure of the material is optimized using heat treatment to avoid brittle fracture so that it is suitable for cryogenic service. Their weldability, mechanical reliability, and corrosion resistance make WPL9 fittings a superior option for critical installations in cold service conditions.
