i want to go to US for Bachlore of computer science, I didn't appeared for SAT. my ielts scores are too low only 5.5 band and I am confused if VISA OFFICERS will ask why u hadn't given SAT. what i have to answer pl suggest?
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.
i m going to give an interview for iocl on 5th aug . pls tell me what questions can be answered from metallurgical prospect
