A420 WPL6 is a low-temperature carbon steel grade celebrated for its impressive notch toughness, moderate strength, and excellent weldability. It typically includes elements like carbon, manganese, phosphorus, sulfur, and silicon. The material undergoes normalization or tempering to boost its impact resistance in sub-zero conditions. A420 WPL6 pipe fittings boast high tensile strength (415–585 MPa) and yield strength (minimum 240 MPa), along with good ductility and fatigue resistance, making them ideal for pressure systems in harsh, cold environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
