Steel properties
Standard grade for High Speed Steels; owing to its balanced composition has good toughness and cutting performance, hence many applications.
 
Applications
Cutting tools for roughing or finishing, such as: helical bits, milling cutters of all types, taps, dies, spindles, reamers, thread rolling tools, drill bits, circular saw segments.
Impact tools and those used for working wood. Cold forming tools such as dies and punches for cold extrusion and cutting and fine cutting tools.
 
(1) For tools of complicated shape and cold forming tools, it is recommended that the austenitizing tempreature should be towards the lower end of the range shown. The austenitizing temperatures shown refer to a salt bath quenching. If a vacuum quenching is used, they should be reduced by 10 to 30 deg.C.
