Stainless Steel Custom 465 Heat Treatment
This Material is normally supplied in Condition A (Solution Annealed)
- Heat to 1800° F ± 15° F (982° C ± 8° C), then hold at that temperature for 1 hour. Cool rapidly by quenching for parts under 12", or air cool swiftly for parts over 12"
- Refrigerate to -100° F (-73° C) and hold for eight hours, followed by warming to room temperature
- This should within a 24-hour period
- Please note that this process should be done in a 24-hour timeframe after solution annealing
Achieving high strength levels of Custom 465 requires an additional age hardening step by heating to 900 to 1150°, hold 4 to 8 hours, air cool for sizes under 3", quenching for sizes over 3".
Custom 465 Stainless Steel can be cold and hot worked with the following treatments
- Hot working: Solution anneal before hardening, then heat to 1850-2000° F (1010-1093° C) and air cool
- Cold working: Alloy 465 can be readily cold formed by drawing or rolling
Custom 465 Stainless Steel Machinability
Best machinability is in the overaged H1150M condition, but can also be done in the Solution Annealed condition.
