Basic coated low-hydrogen stick electrode for welding of 1.25% Cr - 0.5% Mo creep-resistant steels. Also suitable for welding 0.9% Cr and 0.5% Mo steels. Welds retain excellent mechanical properties after long exposure to temperatures up to 500°C. Designed for applications in oil refiners, oil and gas industry, chemical industry, ammonia synthesis processes and thermal power plants for heat exchangers, boilers, pipes and pressure vessels with operating temperatures up to about 550°C. Can also be used for cladding and repairing of casting molds. *( X and J Factor controlled “on request”)
