EM 251

Properties and Applications

Basic type electrode for welding and building of Cr-Ni-Mo- V containing steels and cast steels with similar composition. Suitable to use in machine building and construction of apparatus, as well as for repair welding of components made of similar steels grades. Preheating, interpass temperature and post-weld heat treatment should be done in accordance with base metal to be welded.
