Product Description

About products

1.2713/5CrMnMo hot work die steel is a hammer forging die steel without nickel, and its properties are similar to that of 5CrNiMo steel. 5CrMnMo die steel is suitable for making medium-sized hammer forging dies with side length ≤ 400mm. This steel is a hot work die steel. In addition to the slightly poor hardenability and heat fatigue resistance, 5CrMnMo steel has the same properties as 5CrNiMo steel, and the hardenability is slightly poor. This steel is suitable for making various types of forging dies that require high strength and wear resistance. When high toughness is required, electroslag remelting steel can be used.

heat treatment

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
