Carpenter Micro-Melt® HS-76 Alloy (AISI M48)

Micro-Melt® HS-76 alloy is a super high speed steel possessing abrasion resistance equal to T15 and superior red hardness to T15 and M42. It is heat treatable to HRC 70 and is a good candidate for special purpose cutting tools where the ASTM M40 series high speed steels are inadequate. 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, Extrusion die inserts, Lathe tools, Form tools, Broaches, Reamers, Cut-off toolsInformation provided by Carpenter Technology Corporation.Micro-Melt® is a registered trademark of Carpenter Technology Corporation.
