š” Key Repair & Operation Instructions:
- Unrivaled Resistance to Heat Checking: Low silicon and optimized Cr-Mo-V chemistry provides far superior ductility and hot yield strength compared to standard H13.
- Preheating Control (TIG): Maintain strict preheating at **320Ā°Cā400Ā°C** before TIG welding to eliminate cold cracking along the heat-affected zone.
