CarTech Micro-Melt M48 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 other ASTM M40 series high speed steels are inadequate

CarTech Micro-Melt M48 alloy is suggested for use where high red hardness, high abrasion resistance, and good toughness are required.

The advantages of CarTech Micro-Melt 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:
CarTech Micro-Melt M48 alloy has found applications in tools such as:
milling cutters
form tools
end mills
broaches
cutting tool inserts
reamers
extrusion die inserts
cut-off tools
lathe tools
