Drawn annealed steel 52SiCrNi5


Quality: Drawn annealed spheroidal 52SiCrNi5

Diameter: from mm 4.00 to 28.00
Diameter tolerance h9

Heat treatment:
HARDENING: 850°/870° in oil
The pieces should be held into the wave to the temperature, according to the diameter (at least 10/12 mins.) in order to allow the austenitizing process

TEMPERING (stress relieving): 400°/460°
The pieces have to keep on the temperature at least 30 minutes and until to a maximum of two hours.
