hardness Things made of east and west steel have high enough hardness after heat treatment. For example, things used for metal cutting are generally above HRC60. Under the high cutting speed and high temperature heating conditions produced by machining hard materials, East and West can still adhere to high hardness and excellent red hardness. Carbon east and west steels and alloy east and west steels can still maintain high hardness under the working temperature of 180 ºC~250 ºC and high speed east and west steels at about 600 ºC. Red hardness is very important for hot deformation die and high speed cutting tool steel.

Recommended quenching specifications for 5CrMnMo steel: 3Quenching temperature /ºC intermediate temperature /ºC cooling hardness (HRC) 820 ~ 850 oil 150 ~ 180 ~ 150 ~ 180ºC after the small mold cold air, large and medium mold immediately temper 52 ~ 58 Note: 1. The upper limit of heating temperature for medium forging die and the lower limit of heating temperature for small forging die are adopted. 2. In order to reduce the stress and deformation of the die after quenching, it is best to cool the air to 740 ~ 760ºC during quenching, and then cool the oil to about 150 ~ 180ºC, take out and annealing immediately;
Recommended tempering specifications for 5CrMnMo steel: Tempering purpose Heating temperature /ºC Heating medium hardness (HRC) Eliminate stress, stabilize structure and size
