PROPRIETARY X17U4 Heat Treatments
- Aging I: Harden for 4 hrs at 550°C followed by air cooling.
Aging II: Harden for 4 hrs at 620°C followed by air cooling.
Delivered condition: We supply this steel either in the “solution treated” or in the “solution treated and aged” condition.
Aging: After solution treatment this steel must undergo precipitation hardening (or "aging") in order to achieve its mechanical properties.
The two most common aging treatments are: 4 hours at 550°C for UTS: 1070 MPa; 4 hours at 620°C for UTS: 950 MPa.
Other strength levels can be achieved. The highest level corresponds to aging for 1 hr at 480°C for UTS: 1300 MPa approx. At this ultimate level of resistance, there is a risk of stress corrosion in service.
