State check
Do not assume one route applies to every PH alloy. Some grades need intermediate treatments. Ageing can change dimensions as well as properties, and machining may be scheduled before or after ageing according to the part requirements.
Next step
Confirm the exact alloy, starting condition, specified final condition and inspection requirements. A solution-treated condition must not be treated as automatic approval for service.
Carry the final condition into the material record
A process name does not supply a universal hardness, strength, temperature, dimensional allowance or cutting parameter.
