CarTech Micro-Melt M4 alloy is a molybdenum-tungsten powder high speed tool steel containing high carbon and vanadium. This grade possesses very high wear resistance coupled with high strength.

Many of the benefits realized in the use of CarTech Micro-Melt powder metals, such as CarTech Micro-Melt M4 alloy, are a direct result of the refined microstructure (smaller, more uniformly distributed carbide particles and a finer grain size) and the lack of segregation in the powder metallurgy product. These advantages include ease of grinding, improved response to heat treatment, greater wear resistance, and increased toughness of the finished tool.

In addition, Carpenter's unique hot rolling and rotary forging capabilities impart minimal distortion characteristics to these alloys.

Applications:
CarTech Micro-Melt M4 alloy may be considered for many types of tooling applications where good toughness, improved grindability and wear resistance are important.

Possible applications for this alloy may include:

Lathe tools
Planer tools
Drills
Taps
Reamers
Broaches
Milling cutters
Form cutters
Thread chasers
Hobs
Counterbores
Insert-heading dies
