Steel properties :
As a tungsten molybdenum high speed steel, it widely used in the production of machine tool bits,cold forming tools and cutting tools. 1.3343 high speed steel offers high toughness combined with good cutting powers and will withstand increases in temperature without losing its temper.
______________________________________________________________________________________________________________
Applications :
Tools for cold work and for considerably stressed tools for cutting of material with the middle and higher firmness such as tools requiring especially good toughness, efficient milling cutters, drills, taps, reamers, saws of all kinds, cutters for gearing, screw dies, brooches, inserts for circular saw blades, slotting tools and wood working tools. The steel is appropriate for coating, nitride of titanium. Bimetal bandsaw blades, Tool bits,High speed steel tool bits, slitting cutters, slitting spacers.
