Nihonweld NHF-13H description: NHF-13H is a lime type electrode in which Mo is added to the base of 13% Cr steel. The weld metal shows martensitic structure, it has excellent resistance to heat, corrosion and abrasion, also has good crack resistibility. And its usability is good and rich surfacing welds can be obtained. It is designed to prevent the dilution from base metal because of shallow welding penetration. Therefore, it provides weld metal of stable hardness of first-layer welding. But machining as welded condition is impossible.
