Basic type electrode for welding hot work tool steels and cast steels with similar composition, which are subjected to high temperatures up to 550-600°C. Suitable for welding Cr, Mo, V, W containing low alloy steels and hot work tool steels. Also suitable for surfacing and hardfacing on machine parts, forging and drawing dies, shafts which were made of hot work tool steels and similiar compositions. Preheating, interpass temperature and post-weld heat treatment should be done in accordance with base metal to be welded.
