Diehl Steel has introduced Marshalloy MQ/FM pre-hardened alloy steel. The mold quality, free machining steel is a premium P-20 produced through a propriety melting and refining process and is suitable for plastic injection mold applications as well as short run tools and dies. It shows superior cleanliness, polishability, machinability, uniformity and hardenability.

The unique characteristics of Marshalloy MQ/FM allow it to be polished to an extremely high finish. The material is tested to rigorous standards to ensure uniformity of structure and exceptionally low inclusion levels. It is decarb-free and stress-relieved, making it ideal for EDM processes.

Prehardened to 262/321/BHN, the balanced composition ensures uniform cross-sectional hardness and maintains the specified hardness throughout the plate. Minimum variation within any plate is 30BHN.
