Marshalloy MQ®

Cleanliness & Polishability to Meet Demanding Specifications

Whether you make mold cavities for plastic injection molding, tool frames, holder blocks, or anything else that requires easy-to-handle, pre-hardnened alloy steel plate, Marshalloy MQ® deluxe plate is the perfect material.

Because Marshalloy is pre-hardened to 280/321 BHN, it features uniform hardness throughout the plate, which makes for easier machining without compromising cleanliness.

Marshalloy MQ® is available decarb-free and stress-relieved, and may be used effectively in EDM processes.

  • > Cleanliness/Polishability
  • > Hardenability
