This ER 80S-D2 / W Z2Mo TIG wire is a copper-coated, heat-resisting low-alloy steel filler containing approximately 0.5% molybdenum, designed for applications requiring high tensile strength and elevated-temperature performance. It produces excellent weld quality and bead appearance on carbon and low-alloy steels, even when welded at higher currents.
The wire offers a stable arc with low spatter, making it well suited to demanding industrial environments. With recommended service temperatures of up to 500 °C, it is commonly used for welding creep-resisting steels in steam boilers, pressure vessels, gas pipelines, heat exchangers and petrochemical installations.
Manufactured using virgin raw materials from specialised steel mills, this green wire delivers consistent quality, mechanical reliability and repeatable results.
