Low alloy basic-coated electrode with 1.25% Cr and 0.5% Mo content, with low carbon concentration (less than 0.05%), to be used for the welding of creep resistant steel. Suitable also for the welding of steels with 0.9% Cr and 0.5% Mo content. The chemical composition of weld metal guarantees a low sensitivity to solidification cracking, especially during the first pass welding. It is used in chemical industry and in the ammonia synthesis process, for heat exchangers, boilers, piping and pressure vessels for temperature service up to about 550°C. It will also find applications in the petro-chemical industries, suitable for facing on casting and for casting repairs.
