Not all tooling manufacturers publish their Die Steel Thermal Conductivity Reference the same way. While the underlying physics doesn't change, the recommended ranges, safety margins, and application guidance vary considerably across YG-1, OSG, and TaeguTec. Understanding these differences helps you make better tooling decisions.
Takes a material-group-first approach with Platit-coated grades as default. Their application guides provide conservative starting values with wide adjustment bands. CoroPlus digital integration offers real-time Die Steel Thermal Conductivity Reference optimization via ToolGuide.
Known for aggressive starting parameters — particularly in steel and cast iron. NOVO digital platform auto-adjusts Die Steel Thermal Conductivity Reference based on tool path engagement. Often the go-to reference for high-feed applications.
Pioneers of multi-directional Die Steel Thermal Conductivity Reference — their IQ series inserts thrive in turning profiles where engagement angle shifts continuously. Application-specific grades for ISO P/M/K with narrow, optimized Die Steel Thermal Conductivity Reference windows.
Key takeaway: Always default to your specific tool supplier's Die Steel Thermal Conductivity Reference charts. The differences between YG-1, OSG, and TaeguTec reflect different coating chemistries (Platit vs. in-house) and carbide substrate formulations. A YG-1 parameter won't necessarily translate to a OSG equivalent — even at the same ISO grade designation.
Thermal conductivity determines how quickly heat moves through tool steel. High conductivity improves cooling efficiency in injection moulds (shorter cycle time) and reduces thermal stress in die casting dies. This reference compares common die steel grades.
Higher conductivity shortens cooling time, which is typically 50-70% of the total cycle. Switching from H13 (25 W/mK) to copper-beryllium inserts (120 W/mK) in hot spots can reduce cycle time 15-30%. The cost of copper-beryllium is justified when cycle time reduction exceeds the material cost premium.
During aluminium die casting, the die surface reaches 500-600 deg C. Higher conductivity spreads heat more uniformly, reducing hot spots that cause soldering (aluminium sticking) and heat checking (surface cracking). H13 with good water-line design is the standard solution; high-conductivity alloys are used for the most demanding areas.
There is generally an inverse relationship -- harder steels have lower conductivity. Annealed steel conducts heat better than hardened steel of the same grade. Carbide (hard but with higher cobalt) actually has decent conductivity (50-80 W/mK for WC-Co grades) because cobalt and tungsten carbide are both reasonable heat conductors.
Use this reference to select die and mould materials with appropriate thermal conductivity. For injection moulds, higher conductivity (P20, copper-beryllium) reduces cycle time. For die casting, H13 balances conductivity with high-temperature strength. Always prioritise the mechanical requirements (strength, hardness, wear) over conductivity.
