Steel group: High speed steels
Properties: No data
Applications: General purpose drills, broaches, reamers, knives, taps, dies or inserts for cold work tooling, where high wear resistance is required, milling cutters, saws.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Cutting tools: 1180-1220 ºC, cold work dies 1080-1160 ºC. Hardening procedure must involve pre-heating at 400/500 ºC followed by other at 860/880 ºC. For large tools, it is also recommended another pre-heating at 1050 ºC. After pre-heating, hardening at suitable austenitizing temperature may be conducted, followed by quenching down to room temperature. A protective atmosphere is absolutely necessary.
Tempering: 560 ºC. Double tempering treatments, of at least 2h, are required and after each one tools must cool down to room temperature.
