1.3343 (DMO5)

Description

High-speed steel, high strength at elevated temperatures, good toughness,

high compressive strength, good wear resistance. Similar to AISI M2.

APPLICATION AREAS

Standard material for machining tools, e.g. drill bits, milling cutters, screw dies, broaches, inserts for circular saw blades. slotting tools and wood working tools. In addition cold forming tools e.g. cutting and blanking tools, cold extrusion punches and dies. Excellent base material for PVD/CVD coating.
