Matrix High Speed Steel

Matrix High-Speed Steels by International Mold Steel

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.
