International term:

ASTM A331, A505, A519, A646
AISI 4137, 4137H, SS2244

Application field:

42CrMo4 is a versatile heat-treated steel , which is characterized by its high strength and toughness . It is mainly used in mechanical engineering , and for vehicle and automotive use . Gear, crankshafts and connecting rods are manufactured from it.


42CrMo4 is very difficult to weld and is therefore not suitable for welded structures . If welding is unavoidable, a heat treatment is recommend .

Benefit of sawn cuts:

The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.

Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
