Basic coated low-hydrogen stick electrode for welding of 0.5% Mo creep resistant steels and high strength low-alloy (HSLA). It retains excellent mechanical properties after long exposure at temperature up to 500°C, while retaining good toughness at low temperature (down to -40°C). Applications include pipes and pressure vessels with operating temperatures up to 550°C. Pre heating at 100 / 150°C is recommended.
