    General descriptions:

     M42 is a Mo type of high-speed tool steel with high levels of carbon(1.10%) and cobalt(8.00%).It can be heat treated to a hardness of  Rockwell C 68-70 ;in fact, it is a super high-speed steel.Its combination of composition and properties makes it suitable for machining high-hardness alloys and difficut-to-machine superalloys.Excellent wear resistance and high hot hardness are obtained in Type M42 without loss of cutting-edge toughness.
