17-7 RH950 Treatment on 17-4 PH
17-7 RH950 Treatment on 17-4 PH
(OP)
Ok, I've got inseperable assembly made from both 17-7 & 17-4. The 17-7 is in the TH1050 condition and the 17-4 is in the H1075 condition. I'm interested in what a solution anneal(1950F)+austenite condition(1750F-> -100F)+age(950F)will do to the properties of the 17-4? I know the double aging process for 17-4 H1150M requires a two hour 1300-1500F treatment before final aging. I was thinking I could reduce the austenite conditioning step for RH950 from 1750 to 1500 since I have data on what this does to the RH heat treatment. In the end, I'll need to verify properties but I was wondering if anyone would know the effect. I'm sure someone has accidentally heat treated one of these two metal's to the other's heat treatment cycle.
Thank you
Thank you
