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?


what should be the exact suction capacity for 3 to 5 mt capacity lead rotary furnace and length of duct line for proper suction for same


What is the material of E185


what are different grades of mild steel available for making machine structure (housing)


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.
