Micro-Melt® A11

UNS #T30111

Micro-Melt® A11 is a high vanadium tool steel possessing wear resistance superior to most other tool steels, including the high speed steels, along with good strength and toughness characteristics. Equivalent in hardness, wear resistance and heat treating response to CPM 10V* alloy. * CPM and 10V are registered trademarks of Crucible Materials Corporation. Considered for applications requiring excellent wear resistance at moderate working temperatures 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.
