Thanks ED. Overaged is Double heat treated at 1150 right ? What's the maximum reduction possible in this condition ? am I right to assume approx. 20% ? Further re-anneal, re-overage and cold draw again ? Repeat the process till you achieve the desired reduction ?

Can anyone tell me what's the exact process to cold roll 17-4PH from say 4mm thickness sheet to 0.4mm ? That's a 90% reduction...considering at 4mm we start with 17-4PH "A" conditions, how many times the alloy needs to be heat treated, annealed, re-heat treated, re-annealed etc. ? What's the...
