Description
Basic coated electrode
This basic coated high recovery electrode deposits a weld metal with a fully austenitic structure with carbide precipitations and scaling resistant up to 1000°C. Product for welding and cladding of heat resistant fully austenitic steels and similar alloyed steel casts for high temperature applications. Its basic coating ensures excellent positional welding characteristics with good gap bridging ability. Ease of slag removal reduces post-welding cleaning operations to a minimum.
