Basic low-alloy flux cored wire for welding of high strength low-alloy steels (HSLA) and 0.5% Mo creep-resistant steels. Suitable for vertical-up single or multi-pass welding. It retains good mechanical properties after long term exposure to temperatures up to 500°C, while ensuring good impact toughness down to -40°C. Typical applications are pipelines and pressure vessels with operating temperatures up to 550°C and steel buildings. To be used under the shield of Ar+CO2.
