CarTech Micro-Melt PD#1 Steel

CarTech Micro-Melt PD#1 Steel

Steel name: CarTech Micro-Melt PD#1
Diagram No.: 2318
Chemical composition in weight %: 1.10% C, 1.20% Si, 0.25% Mn, 7.75% Cr, 1.60% Mo, 2.35% V, 1.10% W
Steel group: PM cold work tool steels
Properties: CarTech 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 CarTech 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.
Applications: CarTech Micro-Melt PD #1 alloy may be considered for many types of cold work tooling applications where a combination of excellent wear resistance and good toughness is required. Potential applications for this alloy may include: Punches, rotary shears, blanking dies, chipper knives, slitter knives, thread rolling Dies.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Micro-Melt PD #1 alloy can be heat treated in salt, vacuum, or controlled atmosphere furnaces, with precautions being taken to avoid decarburization during the heat treatment operation. Preheat to 1550/1600°F (843/871°C), then transfer to 1850/2050°F (1010/1121°C). Hold 45 minutes at temperature. Following austenitizing, parts may be air cooled to room temperature. For vacuum furnace treating, a minimum 2 bar backfill with inert gas is desired for the quench.
Tempering: Tools should be tempered immediately after the completion of the quench. Triple tempering at 2 hours per temper is suggested, using a minimum tempering temperature of 950°F (510°C). Tools should be cooled to room temperature between tempers.
