Stoody ThermaClad 454
The ThermaClad 454 deposit is a modified tool steel. It is specifically designed for weld overlay on rolls in the hot strip mill and provides the greatest resistance to thermal fatigue and abrasion. Overlays exhibit excellent wear properties, hot hardness, and uniform tempering response. The alloy requires a double temper - two temper cycles at eight (8) hours each.
Features
- Hardfacing overlay for: Pinch rolls, Vertical edger rolls, Scale breaker rolls, wrapper rolls
