Description
Non-synthetic basic coated electrode depositing Ni-Cr-Mo-Nb weld metal. Highly crack resistant weld also possesses good corrosion resistance characteristics. It has scaling o temperature up to 1100 C in air. It is ideally suited for welding Cr-Ni-Mo austenitic stainless steels to themselves, to duplex stainless steels, to Ni-Cr-Mo alloys, and to steel or for just overlays. Typical specifications for the Cr-Ni-Mo stainless steel base metal are A240, A167, A182, A249, A276, A312, A358, A373, and A479, most particularly the grade UNS S31254 / 254 SMO / 6% Mo SS type. In a chloride containing environment, the fully austenitic weldmetal exhibits high resistance to Pitting, Crevice Corrosion & Stress Corrosion Cracking. It is ideal for Sulphuric and Phosphoric acid media that has been contaminated by chlorides. It can also be used for welding of 625 and 825 grade Ni-based alloys.
