What is DPM450 (SPM20CV)
The material DPM450 is a powder metallurgically produced steel with a very high carbon and chromium content. Due to its higher carbide content, the DPM450 material combines extreme wear resistance and hardness with particularly good toughness.

Special properties
Powder metallurgical steels (PM steels) are obtained in an alternative manufacturing process for casting blocks and, due to their good properties, are used particularly in large-scale production. The powder is strongly isostatically compressed during production, which leads to fewer air pockets and a homogeneous steel structure. Due to the highest possible degree of purity, PM steels are more resistant than conventional tool steels. Due to their high wear resistance and hardness, they require a much less frequent tool change and are therefore also more economical (service life!).

Sawn blank
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.
Frequently asked questions about material DPM450:
It is a powder metallurgy (PM) steel with a very high carbon and chromium content. The manufacturing process results in an extremely pure steel with a very fine and uniform distribution of carbides.
It offers extreme wear resistance, high toughness, good compressive strength, and high dimensional stability during hardening.
The alloy essentially consists of 1.90% carbon, 20.00% chromium, 4.00% vanadium, 1.00% molybdenum, and 0.60% tungsten.
