R6M5
Steel has an increased tendency to decarburization, increased viscosity, good wear resistance, good grindability.
For all types of cutting tools in the processing of carbon alloyed structural steels; preferably for the manufacture of thread-cutting tools, as well as tools operating with shock loads.
