Annealing: 840-860 ℃ hardness: ≤ 229HB

The quenching temperature: 840-870 ℃, oil cooling or air cooling, hardness: ≥ 50HRC.

The tempering temperature: 550-650 ℃, air cooling.

Hardness: 30-38HRC

Hardness: 30-38HRC

When producing mould, the first general quenching and tempering treatment, the hardness of 28-35HRC, its performance is better than 3Cr2Mo.

The steel can be further improved the surface properties ofcarburizing.
