Why do metallurgy engineers so sucessfull in their profession so that they dont think beyond their dreams?
5 9991What do you do with the super alloys in the present working culture so as to improve the technology for general people?
2 5497Why do the Gamma Prime and Gamma Double Prime phases play such an important role in promoting strength in the superalloys?
1 6663Why do some of the latest 'single crystal' superalloys contain concentrations of the grain boundary strengthening elements, e.g. carbon and boron?
1574The processes used to fabricate the superalloys seem fairly mature. Is much process development going on?

I currently use 17-7 PH stainless which is hardened to condition CH after forming. raw matl is .1.75"X .12" X .008". Its main usage after hardening is silicon wafer retainer where it's contantly cycled up and down to putin and remove wafer after 40-60 sec process at 400C temp. At this high temperature this part seemed to deform after a a couple of hundred wafer which is what it was designed for in the first place. THere is a proposal to go to a different material to increase lifeline of this part. My question is..... can 321 SST be a plugin replacement. I know this has a higher temp rating but how about its forming characteristics, will it have spring properties, and wont become brittle after prolonged exposure to 400C.
