dear sir
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
please help me

Why same casting has different hardness and machineability
properties? One spot it is found hard for machining and
another spot soft? It is FG 260 grade for Cast Iron.
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?
Why are the superalloys sometimes subjected to secondary
melting processes?

When might secondary melting processes be unnecessary?

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

What happens to the microstructure during service exposure?

any input on how to spec out(if possible) a larger grain
structure(3/8" or larger) on a Al 6061 forging material.
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.
