Heat treatment of 17-7 ph-austenite cond.
Heat treatment of 17-7 ph-austenite cond.
(OP)
One of our heat treaters mistakenly used the 1750 RH table for time at Autenite cond temp(only 40 min) when he should have gone 90 min. Final cond should be TH1050. He then followed the Transformation below 60° and he Age at 1050 for 90 min.
I thick the material responded and got the correct hardness.
Do we re-heat-treat?Sol'n Aneal? Reaustenite Cond? Leave it alone?

Can not run a tensile.

If you can't test the actual parts you should always runs coupons from the same lot of sheet along with each load.
