Stoody SOS 438
The 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
- Thermal Fatigue Resistance: Excellent
- Abrasion Resistance: Very Good
- Comprehensive Strength: Good
- Hardness, HRC (as welded): 45-49
- Machinability with carbide tools: Fair
