Matrix High-Speed Steels
Economical Alternative to Powders
The first Matrix High Speed Steels commercially available in
Japan were the YXR series produced by Hitachi Metals, Japan's
leading producer (by volume) of High Speed Steels. YXR33 (warm and
hot forging tooling), YXR3 (warm and cold forging tooling) and
YXR7 (high strength, high hardness cold work tooling) were soon
followed by Nachi-Fujikoshi's MDS1, MDS3, MDS7 and Daido Steel's
MH85 and MH88. These steels are all single melted, air melted
steels.
 Recently,
Daido Steel introduced the second generation of Matrix High Speed
Steels, dubbed "The Dream Steels". These steels are double (ESR)
melted steels for improved toughness, fatigue resistance, strength
and cleanliness when compared to the conventionally melted high
speed steels.
DRM1 is for warm and hot forging tools, DRM2 is for warm and
cold forging tools, and DRM3 is a high hardness (HRC66) high
strength tool steel.
