DESCRIPTION

 

E M42 is a highly cobalt alloyed high speed steel to be used when the demand for hot hardness is of great importance. E M42 has a good machinability and a good wear resistance .

 

HEAT TREATMENT

  • Soft annealing in a protective atmosphere at 850-900°C for 3 hours, followed by slow cooling 10°C per hour down to 700°C, then air cooling.
  • Stress-relieving at 600°C to 700°C for approximately 2 hours, slow cooling down to 500°C.
  • Hardening in a protective atmosphere with pre-heating in 2 steps at 450-500°C and 850-900°C and austenitising at a temperature suitable for chosen working hardness.
  • 3 tempers at 560°C are recommended with at least 1 hour holding time each time.
