Forging

Forging of this steel should be carried out between 2200 and 1650 º F (1200 and 900 º C). The lower the finishing temperature from forging, the finer will be the grain size. This alloy should ideally not be forged below 1650 º F (900 º C) and should be slow cooled after forging.

Heat treatment

1.Nominal normalizing temperature:840-890°C

2.Hold the temperature for several hours
3.Cooling in the air


Annealing  For 16CrMo44
1.Nominal Annealing temperature:680-720°C
2.Cool slowly in the furance
3.Maximum Brinell hardness of 217

Hardening and Tempering(QT)  For 16CrMo44
1.Nominal Hardening temperature:850-870°C
2.Hold at this temperature then quench in oil or water
3.Tempering  as soon as possible when the temperature low to ambient
4.Heat uniformly to the suitable temperature of 550-640°C
5.keep the material out of the furnace ,then cool in the air


Mechanical Property( for reference only)
1.Tensile strength: 740MPa
2.Yield point: 635MPa
3.Percentage reduction of area after fracture: 50%
4.Elongation after fracture: 17%
5.Impact test (+20°C): Transverse – 27~32J; Longitud – 60~80J
