Basic coated low-hydrogen electrode for welding of 9% Cr, 1% Mo martensitic creep-resistant steels. Mechanical properties after long term high temperature exposure (up to 650°C) are guaranteed thanks the micro-alloying with Nb, V and N. Specifically designed for the welding of creep resistant P91 steels in the petrochemical industry and thermal power plants for components such as heaters, main steam piping and turbine casings.
