Bohler Fox DMV 83 Kb (Creep Resistant) Low Alloy Steel Stick Electrodes
The Bohler Fox DMV 83 Kb are specifically engineered to maintain its mechanical integrity under high heat and pressure, making it the industry standard for welding 14MoV6-3 (1¼Cr-1Mo-V) creep-resistant steels.
Features
- Offers excellent puddle control and weldability in all positions except vertical-down.
- Yields a highly ductile, crack-resistant weld deposit featuring uniform bead formation and excellent radiographic (X-ray) quality.
- Typical procedures for CrMoV materials require strict preheating/inter-pass control and a post-weld stress-relieving temper cycle to achieve optimal tensile and creep rupture strength.
