Carpenter Specialty Alloys
Carpenter Micro-MeltR PD #1 alloy, a premium powder-metallurgy iron-base alloy grade, is suitable for use in cold-work tooling applications requiring wear resistance and toughness. Nominal chemical composition of the alloy is 1.10% C, 0.25% Mn, 1.20% Si, 7.75% Cr, 1.6% Mo, 1.10% W, 2.35% V, bal Fe. The air-hardening cold-work steel has a fine, uniform carbide distribution. In laboratory tests, a hardness of 60-63 HRC was achieved using austenitizing temperatures ranging from 1850 to 2050F (1010 to 1120C).
