42CrMo alloy steel hardness: annealing, 147~241HB Mechanical properties of 42CrMo alloy steel:

Tensile strength σb (MPa): ≥1080(110)

Yield strength σs (MPa): ≥930(95)

Elongation δ5 (%): ≥12

Sectional shrinkage ψ (%): ≥45

Impact energy Akv (J): ≥63

Impact toughness value αkv (J/cm2): ≥78(8)

Hardness: ≤217HB In order to increase the mold life to more than 800, 000 molds, the pre-hardened steel can be hardened by quenching and low-temperature tempering.

When quenching, preheat at 500-600℃ for 2-4 hours, then keep warm at 850-880℃ for a certain period of time (at least 2 hours), put it in oil and cool it to 50-100℃, then air-cool it.

The hardness can reach 50-52HRC after quenching.

To prevent cracking, low-temperature tempering at 200℃ should be carried out immediately.

After tempering, the hardness can be maintained above 48HRC.
