High Strength 631 Cold Rolled Stainless Steel Strip 17-7PH Sheets
Material JIS SUS631 ( 17-7PH ) is a precipitation hardening, austenitic stainless steel of the 17Cr-7Ni PH type,
with a high tempering effect and good structural stability.
The SUS631 stainless grade is characterized by:
- High tempering effect, up to 400 MPa
- Low relaxation at high stresses and elevated temperatures
- Higher fatigue strength
- Very small distortion during tempering
- High service temperatures
- Service temperature: up to 350°C (660°F)
SUS631 stainless is suitable for complex, formed springs with high demands on spring force and service life.
It is also suitable for use at elevated temperatures.
