Micro-Melt® T15

UNS #T12015

Micro-Melt® T15 is a high-carbon tungsten-cobalt-vanadium high speed powder metal tool steel possessing excellent abrasion resistance and red hardness. May be considered for many types of tooling applications where hot hardness, improved grindability, and wear resistance are important. 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.
