5CrMo
Description
Basic coated electrode for creep resisting 5%Cr-0,5%Mo steels
Basic coated electrode designed for the welding of Cr-Mo alloyed steels. The 5Cr-0.6Mo type weld metal develops a martensitic-bainitic microstructure that ensures excellent mechanical properties both in tempered and quenched-and-tempered conditions. It is particularly suitable for joint welding of creep-resistant steels and cast steels used in the thermal power and chemical industries, and it is approved for long-term service under creep conditions up to 650 °C. The electrode can be used in all positions except vertical down, offering a stable arc, excellent weldability, and easy slag removal. During solidification, the deposit remains crack-free, ensuring reliable performance. Designed for high-temperature service, it is widely applied in petroleum refineries, pipelines, heat exchangers, pressure vessels, and boiler superheaters.
