Re-Heat Treat 15-5 due to wrong condition

Re-Heat Treat 15-5 due to wrong condition

Re-Heat Treat 15-5 due to wrong condition

(OP)
We had a requirement for a supplier to Heat Treat parts to 180-200 KSI and achieve a hardness of 40 - 43 HRC per a customer specification

The parts were processed to condition H1025 resulting in hardness of 36 - 37 HRC. I assume they should have been processed to condition H925 to achieve the desired results.

Question: Can these parts be re-heat treated (reworked) to Condition H925 or at a higher temperature than what the parts were originally processed to in order to meet the 180-200 KSI and 40 - 43 HRC?

RE: Re-Heat Treat 15-5 due to wrong condition

Sure, they need to be annealed and then aged.
You should have called out the specification and aging temp, then there wouldn't have been a misunderstanding.
