Material Notes:

Description: High speed steel produced by powder-metallurgy methods with highest red hardness, compressive strength and wear resistance. The PM technology imparts to the material also excellent toughness and machinability properties, e.g.. high satisfactory grindability.Applications: Heavy-duty machining tools-Not only for the machining of steels but also for nonferrous metals such as nickel-base and titanium alloysshaper cuttershobsmilling cuttersbroaching tools of all typestapstwist drillschasing toolsreamersbimetal strips for saw blades Tools used under extreme compressive stresses-e.g... precision blanking tools for high-strength materials (shaping punches and dies)
