A core wire alloyed covered electrode with basic coating for shielded metal arc welding. The 2,25Cr-1Mo type weld metal exhibits a bainitic microstructure with favorable mechanical properties in tempered and quenched and tempered condition. Under certain conditions applications in the as welded condition is possible. The range of application covers joint welding of similar alloyed creep resistant steel and steel casting in thermal power and chemical industry. Suitable for application under creep condition at design temperatures up to 600ºC. Due to the low content of residual and tramp elements the weld metal offers a Bruscato factor < 12 ppm. Thus, being resistant to temper embrittlement and complies with the requirements on step-cooling testing. The basic coating guarantees low level of diffusible hydrogen in the weld metal.
