17-7PH / 631 Precipitation hardening stainless steel strip, coil, sheet, 

17-7PH(631),There are three kinds of delivery status: soft state, half-hard state, hard state.
Hardness range: soft state HV≤300, half-hard state HV 300-350, hard state ≥350
After aging can increase the biggest 80 HV hardness value.
 
Shape control:
  1. hard state delivery easy to control,Hardness about HV380.
  2. half-hard state easy to control to.
  3. soft state hardness Value range is larger, HV200 -250,
 
 
B.for hard spring do you usually do, such as the valve saucer reed, electrical spring leaf, etc.,
When machining deformation is small, because material is hard to prevent cracking broken soft material state generally is suitable for deep drawing.
