What's the exact difference between M2 & 1.3343 steel grades

  1. Aug 5, 2015 #1
    I know the two steel grades: M2 tool steel and 1.3343 steels are similar. But the M2 has Mn element while 1.3343 has W elements. what would be the differences with such elements ?

    There are different grades of HSS for different purposes .

    With low intensity machining and common metals most HSS grades are equivalent .

    With high intensity machining some grades of HSS and some metals being machined will weld-bond at the cutting point and a lump of metal will accumulate which degrades the cutting action . This problem is reduced by selecting particular grades of HSS for particular metal being machined .
