4Cr5MoSiV1 Tool Steel
4Cr5MoSiV1 tool steel, by rationally proportioning Cr, Mo, Si and V elements, takes into account thermal hardness, wear resistance and thermal fatigue resistance, and is suitable for various mold application scenarios subject to thermal shock and high-temperature wear.

What is 4Cr5MoSiV1 Tool Steel?
4Cr5MoSiV1 is a representative hot work die steel in the Chinese GB/T 1299 standard, which is the domestic counterpart to the international H13 (DIN 1.2344, SKD61).

4Cr5MoSiV1 Steel Heat treatment suggestions
- Annealing: Hold at 860-890 °C for several hours and then cool slowly, target hardness ≤229 HBW.
- Quenching: Heat at 1020-1080 °C and then air or oil cool. The effective hardness can reach 56-58 HRC (slightly lower for large cross-sections).
- Tempering: Generally, double tempering at 560-580 °C is selected, and the final hardness is stabilized at 47-49 HRC. Tempering at 200 °C can be carried out after processing to relieve internal stress.
