40cr alloy steel heat treatment steel plate

40cr alloy steel is easy to process, and certain toughness, plasticity and wear resistance can be obtained after proper heat treatment. Normalizing can promote the spheroidization of the structure and improve the cutting performance of the blank with a hardness of less than 160HBS. The hardenability of 40cr alloy steel is higher than that of 45# steel.This steel is suitable for surface hardening treatments such as high-frequency quenching and flame quenching.
40cr alloy steel heat treatment:
The first quenching heating temperature (℃): 850; coolant: oil
The second quenching heating temperature (℃):-
Tempering heating temperature (℃): 520; Coolant: water, oil
 
Mechanical properties of 40cr steel plate
