Material Notes:
Micro-Melt® HS-30 alloy is an 8% cobalt, high hardenability tungsten-molybdenum alloyed high-speed steel exhibiting excellent hot hardness combined with good wear resistance and toughness. The advantages of Micro-Melt premium powder high speed steels include ease of grinding, response to heat treatment, more uniform structure, greater wear resistance and improved toughness. In addition, Carpenter's unique hot rolling and rotary forging capabilities impart minimal distortion characteristics to these alloys.Applications: milling cutters, end mills, cutting tool inserts, gear cutting tools, lathe tools, punches and dies, form tools, broaches, reamers, cut-off tools, drills, tapsInformation provided by Carpenter Technology Corporation.Micro-Melt® is a registered trademark of Carpenter Technology Corporation.
