2 Technology Trends in Die Steel Blades
Cold work die steel technology has advanced significantly through material science innovations and precision manufacturing processes. Leading manufacturers like ShengAo employ vacuum degassing, electro-slag remelting (ESR), and powder metallurgy techniques to achieve superior microstructure homogeneity. These processes reduce non-metallic inclusions by 70-80% compared to conventional production methods, enhancing blade toughness and fatigue resistance. Digital simulation of heat treatment processes has improved hardness consistency, reducing hardness variation to ±0.5 HRC across blade surfaces.
Material Innovations & Alloy Development
Premium cold work die steels like D2, Cr12MoV, and SKD11 remain industry standards due to their optimal balance of wear resistance, toughness, and dimensional stability. ShengAo's proprietary modifications to these alloys enhance performance characteristics:
| Alloy | Key Modifications | Performance Benefits |
|---|---|---|
| D2 Enhanced | Vanadium increased to 1.2% | 30% improved abrasion resistance |
| Cr12MoV+ | Molybdenum optimized to 0.6% | Enhanced toughness for impact applications |
| SKD11 Ultra | Carbon controlled at 1.5% | Superior dimensional stability |
Heat Treatment Advancements
ShengAo employs multi-stage heat treatment processes to achieve optimal HRC 58-62 hardness with exceptional consistency:
