Forged of AISI1045 (CK45)  metal material

At first, Pre-Heating to 552ºC,Then heat to forged temperature. Next, Soak at 820-870 °C , ensure heat thorough. Then start forged, the forged temperature no low than 560ºC. After forging, cool slowly .

 

Heat Treatment of AISI 1045 (CK45)

•  AISI1045 (CK45) Annealing

Full annealing of small C1045 forgings is carried out from 1450-1600ºF (790-870ºC)
followed by furnace cooling at 50ºF (28ºC) per hour, to 1200ºF (650ºC) soaking and air cooling.

• AISI 1045 (CK45)  Hardening

Hardening of this grade is carried out from an austenitizing temperature of 1475-1550ºF (800-845ºC) and oil or water quenching.

Flame and induction hardening may be carried out by heating quickly to the desired case depth and quenching in water or oil. This should be followed by a tempering treatment at 300-400ºF (150-200ºC) to reduce stresses in the case without affecting its hardness. A surface hardness of Rc 58 may be obtained by this treatment.

• Quenching of AISI 1045 (CK45)  material

Quenching temperature / ºC | salt bath furnace: 870

Quenching temperature / ºC | controlled atmosphere furnace: 870

The heat preservation time/min: 5 ~ 15

Quenching medium: Water cooling

• Tempering Of AISI1045 (CK45)
