1.2344 ESR (X40CrMoV5-1) Material Data Sheet

The hot work tool steel 1.2344 ESR has an improved material property due to the Electro-slag Remelting Process (ESU). Our ESR material is used when better material purity, particularly high tensile strength and compressive strength are required. Compared to the steel 1.2343 ESR, this material has a higher carbon content and is much harder and more wear-resistant. The material 1.2344 ESR is given a good tensile strength and toughness by the soft annealing.

For forging dies, forging tools, hot shear blades, hot extrusion tools, punches, screw tools, steel bolts and ejector.

annealed max. 229 HB

Weldability: bad

Machinability: 5 (1 = very bad - 10 = good)

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.
