Bohler Fox DMO Kb (Creep Resistant) Low Alloy Steel Stick Electrodes
The Bohler FOX DMO kb is a stick electrode with a basic coating. The weld metal produced by this electrode, which corresponds to type 0.5Mo, has a micro-structure of acicular ferrite and bainite. Thanks to its favourable mechanical properties, it is well-suited for use both in the weld condition and after heat treatment. This electrode is used in a wide range of welding applications, from joining similar heat-resistant steels and cast steels to joining high-strength structural, fine-grained, and pipeline steels. The Bohler FOX DMO kb is approved for long-term use at temperatures up to 550 °C and exhibits excellent impact toughness at temperatures below -50 °C.
Features
- Produces highly dense, defect-free weld metal that consistently passes rigorous radio-graphic inspection.
- Features a metal recovery rate of approximately 115%, increasing deposit efficiency and speed.
-
Operates exceptionally well in all positions except vertical-down (
PG). - Provides a highly smooth, directional arc with minimal spatter and easy slag removal.
