A large volume of vanadium carbides provides the high wear resistance.
M4 tool steel machinability.
It is well suited for premium cutting tools of all types particularly those used for machining abrasive alloys castings and heat treated materials.
Sbsm high speed steel properties comparison.
This specialty high speed steel was developed to have a greater abrasion and wear resistance for high tool life quality and cutting speeds.
The high impact toughness and high transverse bend strength are results of the fine grain.
M4 is an extremely versatile high speed steel with its extremely high carbon and vanadium contents for exceptional abrasion resistance.
There are four principal benefits of cpm high speed steels for tool users.
The grade has an excellent balance of toughness and wear resistance making it ideal for cutting tools and for cold work tooling.
The machinability of m4 steels is comparatively low rating about 40 than that of water hardening tool steels which are much easier to machine.
Heat treatment m4 steels can be preheated at 788 c 1450 f and then rapidly heated to 1218 c 2224 f for 3 5 minutes followed by oil salt bath or air quenching process.
Better annealed machinability b more consistent and safer heat treat response.
Pm steels have excellent grindability vs conventional steels.
M4 high speed tool steel m4 is a molybdenum tungsten high speed steel that is characterized by its high abrasion wear resistance transverse bend strength and impact toughness.
Cpm rex m4 hc powder metal high speed steel.
