CarTech Micro-Melt CD#1 Steel

Steel name: CarTech Micro-Melt CD#1
Diagram No.: 2310
Chemical composition in weight %: 1.70% C, 1.00% Si, 0.40% Mn, 8.35% Cr, 1.40% Mo, 1.50% Ni, 1.00% V
Steel group: PM cold work tool steels
Properties: CarTech Micro-Melt CD#1 alloy is a shock resistant cold work die steel possessing an excellent combination of toughness and wear resistance. The alloy has a fine, uniform carbide distribution resulting from the Carpenter CarTech Micro-Melt powder metal alloy process. This fine carbide distribution, combined with a low sulfur content, results in excellent polishability of dies or tools manufactured from the alloy.
Applications: Coining dies, slitter knives, blanking dies, rotary shears, chipper knives.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Micro-Melt CD#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 1900/1950°F (1038/1066°C). Austenitizing above 1950°F (1066°C) should be avoided due to formation of excessive retained austenite in the tool. Hold 10 minutes per inch of thickness, with a minimum hold time of 10 minutes, up to 25 minutes maximum. Following austenitizing, parts may be air cooled or oil quenched to room temperature, or salt quenched to 1000°F (538°C) followed by an air cool 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. Double tempering at 2 hours per temper is suggested. Tools should be cooled to room temperature between tempers. The following table provides some typical hardness values for various austenitizing/tempering temperature combinations.
