Weld Star A31 ER 80S-D2 Wire [15kg Spool]

The Weld Star A31 (ER 80S-D2) is a premium copper coated, low alloy MIG wire engineered for high performance welding on carbon and manganese molybdenum steels. Featuring 0.5% Molybdenum, this wire is specifically designed for components that operate in high temperature environments up to 500°C, such as steam boilers and pressure vessels.

What sets the A31 apart is its ability to remain stable at high welding currents, delivering a soft arc with minimal spatter and an exceptional bead profile. Part of the "Green Wire" range, it is manufactured from high purity virgin raw materials to ensure consistent mechanical properties, including a high tensile strength of 670 MPa. Whether you are fabricating heavy duty cranes, gas pipelines, or offshore structures, the ER 80S-D2 provides the toughness and X-ray quality soundness required for critical engineering projects.

Key Features

Heat Resistant Deposit: Optimised for creep resistant steels with a maximum working temperature of 500°C.
