Stoody ThermaClad 423Co
ThermaClad 423Co is a submerged arc stainless wire designed specifically for the steel industry as a weld overlay for continuous caster rolls. Cobalt has been added to the alloy the further resist the formation of thermal fatigue cracks (fire cracking) during operation. The alloy has good corrosion resistance combined with excellent wear properties, improved hot hardness, and uniform tempering response.
- Hardfacing overlay for: Continuous caster rolls.
- Cobalt added for added thermal fatigue resistance.
