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.
where do i get previous question papers of metallurgy?
any input on how to spec out(if possible) a larger grain
structure(3/8" or larger) on a Al 6061 forging material.
what are different grades of mild steel available for making
machine structure (housing)
What is equivalent is 2004 cl 5
Please send the Sundar TVS Motors placement papers to this mail id.
what is wedge load test method .
what is offset method .
Any body know when the medicals are starting for the BSI
P.O , if anybody got any call letter please let me know
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 THE ACTUAL DEFINATION OF PLANET?
what is a rate controlling step ? how is it dependent on
reaction path ? explain with an example.
i need some information about prevent eutectic carbide
network(as cast) formation in 12% cr steel casting by
another alloying element(my analays: c=1.2-1.4 cr=11-13
mo=0.2-0.4 ni=0.2-0.4 )or break network carbid after
formation in solidification by heat tretment
