Steel group: High speeds steels
Properties: High-speed steel featuring high resistance to adhesive and abrasive wear in combination with high toughness and compressive strength.
Applications: Blocks for eroding, cold forming tools such as cutting, fine blanking and impact extrusion punches and dies inserts with a very high wear resistance.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1190 - 1230 °C, quenching in oil/compressed gas/air/hot bath, obtainable hardness: 66 HRC.
Tempering: Slow heating to tempering temperature (to avoid forming of cracks) immediately after hardening; triple tempering is recommended.
