Micro-Melt® PD#5

Micro-Melt® PD#5 alloy is an air hardening cold work die steel possessing wear resistance superior to that of conventional grades such as AISI D2, while still maintaining excellent toughness. In addition, it has the compressive strength required for resistance to deformation in tooling applications. May be considered for many types of cold work tooling applications where a combination of excellent wear resistance and good toughness is required. 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.
