1.2343 ESR (X37CrMoV5-1) Material Data Sheet

The hot work tool steel 1.2343 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. By the deposition of sulfur and non-metallic inclusions, the steel has an improved degree of purity, the positive effect on the life of the components.

Hot work tool steel with high heat resistance and wear resistance.
For forging dies, forging tools, hot shear blades, hot extrusion tools, punches, screw tools, steel pins 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.
