Diagram No.: 2782
Chemical composition in weight %: 1.13% C, 1.20% Si, 0.30% Mn, 7.75% Cr, 1.55% Mo, 2.40% V, 1.10% W
Steel group: Cold work tool steels
Properties: This cold-work tool steel produced is a medium-chromium, air-hardening tool steel providing a very good combination of wear resistance and toughness. It is available primarily in round bars for cold-work tooling applications. The steel excels itself through the following properties: A very good combination of wear resistance and toughness, high hardness, nitridability and high dimensional stability.
Applications: Typical applications for this cold-work tool steel: Blanking dies, thread roll dies, punches, coining dies, drawing dies, upsetting dies, cutting tools, cutting rolls and cutting knives.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1040 to 1080 °C / air, oil or inert gas. To increase hardness by 1 to 2 HRC and dimensional stability after quenching, a sub-zero treatment may be used.
Tempering: Temper immediately after quenching (when material after quenching reaches 90-70 °C). At least two tempering treatments are recommended to achieve a uniform tempered microstructure. Slowly heat to reach tempering temperature. Holding time in the furnace: 1 hour for every 25 mm of workpiece thickness, but 2 hours minimum. This is followed by cooling in air. Typical tempering temperatures are 150 to 550 °C
Diagram note: Air cooled from 1066 C and double tempered.
