Micro-Melt® M3

UNS #T11323

Micro-Melt® M3 is a powder metal tungsten-molybdenum high speed steel possessing the superior wear resistance characteristics required for difficult cutting operations. Many of the benefits realized in the use of Micro-Melt® powder metals, including ease of grinding, improved response to heat treatment, greater wear resistance, and increased toughness of the finished tool, are a direct result of the refined microstructure featuring smaller, more uniformly distributed carbide particles and a finer grain size, as well as the lack of segregation in the powder metallurgy product. In addition, Carpenter Technology's unique hot rolling and rotary forging capabilities impart minimal distortion characteristics to these alloys.
