Micro-Melt® PD #1 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. The alloy possesses a fine, uniform carbide distribution resulting from the Carpenter Micro-Melt powder metal process. This uniform microstructure with fine carbide distribution is responsible for the excellent combination of wear resistance and toughness offered by this alloy.
