heat treating 17-4 ph
heat treating 17-4 ph
(OP)
Hello,
Does anyone know the tempering temperature to heat treat 17-4 ph stainless to 50+ Rc?
I know this is really hard, but water is going through it at about 15,000 psi..
any help would be appreciated,
thanks,
brent

17-4.

Check it out, the mid-40's are about all that you can expect.

I agree with israelkk: You should not be designing for hardness in a pressurized system. However, I would guess that you are using a conversion chart & desire to have a tensile strength around 250 ksi, based on your desired Rc50. If so, you won't get there with 17-4 PH (according to Mil-Hdbk-5). H900 Condition is 170ksi yield, 190ksi ultimate.
PH13-8Mo will get you a little higher; "Custom 465 Stainless" will go even higher. Need to look at the whole picture, though - ductility might be a different requirement.
