Bohler Thermanit Chromo 9 V (Creep Resistant) Low Alloy Steel Stick Electrode
Bohler Thermanit Chromo 9 V Mod stick electrode. The basic Coated CrMoVNb Alloyed Electrode is specially designed for welding of creep resistant tempered martensitic 9% Cr steels used for turbine and boiler fabrication in thermal power plants as well as in the chemical industry. Provides good welding characteristics in all positions except vertical down. Recognised for its stable arc, low spattering, good slag detachability and excellent striking and re-striking properties. The chemical composition is optimised in order to provide a high creep resistant and ductile weld metal and meets the requirement for restricted Mn + Ni content (<= 1 wt. %). It is characterised by low hydrogen content and low level of trace elements. This electrode has a half-synthetic cover concept.
