Hardening And Nitriding Treatment 1 2311 Steel Material - China

1.2311 Hardening:

In order to increase the mold life to more than 800, 000 mold times, the pre-hardened steel can be hardened by quenching and low-temperature tempering.

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

After quenching, the hardness can reach 50 -52HRC, in order to prevent cracking, it should be immediately tempered at 200℃ at low temperature.

After tempering, the hardness can remain above 48HRC.

1.2311 Nitriding treatment

Nitriding treatment can obtain a high-hardness surface structure, and the surface hardness after nitriding reaches 650-700HV

(57-60HRC) The mold life can reach more than 1 million times.

The nitrided layer has the characteristics of dense structure and smoothness.

The mold release property and resistance to moisture air and alkali corrosion are improved.
