Thermal processing of 42CrMo4 Steel

Corresponding to the smelting and casting process, the 42CrMo4 steel ingot produced by EAL+LF+VD is mainly used for hot forging, including free forging and die forging.

The 42CrMo4 steel billet produced by the converter + continuous casting process is usually used as a hot-rolled product, and the production efficiency is extremely high.

A final note is that they can be applied to each other, but must match the size of the billet to ensure adequate compression.

For 42CrMo4 steel, after hot rolling or hot forging, it can usually be delivered without heat treatment. But sometimes considering the machinability of the material, 42CrMo4 steel is usually selected for softening annealing treatment.

Choosing 42CrMo4 for normalizing is often to improve processing performance, eliminate internal stress, and prepare a good metallographic structure for final heat treatment.
