Stoody ThermaClad 423
The ThermaClad 423 deposit is a modified martensitic stainless steel. It is specifically designed for weld overlay on continuous caster rolls and provides the greatest resistance to thermal fatigue cracking and corrosion. Overlays exhibit excellent wear properties, hot hardness, and uniform tempering response.
Features
- Hardfacing overlay for: Continuous caster rolls, Table rolls.
