Key Performance Characteristics of SKD6 H11 Steel 1 - High-Temperature Performance

Operating temperature range: 300–600°C (optimal performance below approx.

600°C)

Maintains high hardness at 600°C: approx.

HRC 48 or higher

Strong resistance to tempering-induced softening: secondary hardening peak occurs in the 540–580°C tempering range 2 - Thermal Fatigue Resistance

The most outstanding advantage of SKD6 H11 steel is its excellent resistance to thermal fatigue cracking, making it particularly suitable for die-casting applications involving repeated heating and cooling cycles.
