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.
does any one has gate solutions of 2007,08,09 metallurgical
The requirement for ASTM A217 Gr. WC9 castings for valves components like Body and Bonnet were Normalising at 920+/- 20 Deg. C and Tempring 780+/- 20 Deg. C
The specification calls furnace shall be calibtated within +/-14 deg. C
The Heat Chart shows minimum temperature for normalising 900 to 920 Deg. C, but maximum temperature 960-990 Deg. C
Tempering 780+/-20 Deg. C is within limits and accepted.
Casting having integral test bars, heat trated along with castings passed in chemical znalysis and mechanical properties.
Since normalising maximum temperature is not meeting specification, where castings can be salvaged or renormalised and retempered to meet specification. Whether it will have affect on remechanical properties testing
What is chemical composition and mechanical properties of
IS 2004,Gr-3 and IS 305 AB-2?
how can i prevent the backfire occurrence in copper shaft
What is equivalent is 2004 cl 5
what are the causes of scaling in cast iron, after
subjecting it to annealing process.
Why do some of the latest 'single crystal' superalloys
contain concentrations of the grain boundary strengthening
elements, e.g. carbon and boron?
i m going to give an interview for iocl on 5th aug . pls
tell me what questions can be answered from metallurgical
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
where do i get previous question papers of metallurgy?
i need manual solution of diffusion in solid(shewmon) if
you have plz send for me. tank you
my email : email@example.com
what is a rate controlling step ? how is it dependent on
reaction path ? explain with an example.
Any body know when the medicals are starting for the BSI
P.O , if anybody got any call letter please let me know
