The temperature of 51CrV4 heat treatment

As is known, 51CrV4 heat treatment performance and properties are good. 51CrV4 steel is usually used as spring steel. Under heat treatment conditions, 51CrV4 steel has excellent impact resistance and toughness. 51CrV4 heat treatment requirements are as below.

51CrV4 heat treatment:

c. The temperatures at the lower end of the range are generally applicable to hardening in water and those at the upper end for hardening in oil.
d. Austenitizing period: at least 30 min (guide value).
e. When choosing the quenching agent the influence of other parameters, such as shape, dimensions and quenching temperature on properties and crack susceptibility should be taken into account. Other quenching agents such as synthetic quenchants may also be used.
f. Tempering period: at least 60 min (guide value).

51CrV4 heat treatment is a method for strengthening 51CrV4 material but could also be used to alter some mechanical properties such as improving formability, machining, etc. 51CrV4 steel has high tensile strength and toughness for automobile engineering and gear and engine structures, etc.
