Micro-Melt® M42

UNS #T11342

Micro-Melt® M42® is a powder metal super-high-speed steel possessing a hardness capability of Rockwell C 68/70 used for cutting tools in the toughest machining 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.
