Technical characteristics
Steel R6M5K5 refers to high alloy high speed tool steels. The presence of cobalt material provides a high resistance under conditions of prolonged heating of the working edge of the tool, so this made steel cutting knives of the separation of press and forging equipment, which are technological processes for hot cutting of workpieces made of medium carbon or alloy steels with increased strength and hardness. Quite high, like high speed steels, heat resistance allows you to perform hot/polygonacea cutting of workpieces in automated mode. Cutting force with increased feed rates. Critical temperature limit efficiency tool 600…650°C.

Treatment
Steel is prone to decarburization during heating. Temperature range of forging — 1160…850°C (after the deformation of the forging should be cooled in the wells). Weldability is poor, the tendency to form placenow missing.
