Eutectoid steel contains 0.8 % Carbon and Eutectic steel
contains 4.3 % carbon.

Answer / vishalshah007

there is no exsistance of eutectic steel

eutectic reaction aoocur at 4.03% carbon

but stell get over at 2.03 % carbon

so.. practically as well as teoritically etectic steel is
impossible.

so.. this question is wrong

common guyz.. this is tricky question
think b4 giving answer
thank you..

Answer / guest

composition of carbon

Answer / arun sharma

there is nothing like eutectic steel as such.
steels are the alloys of fe containing less then 2%. and as
we all know eutectic composition is at 4.3% and in this
region only cast iron exist.

Answer / rajakumar

Eutectic is nothing but from liquid we have two solid
form...
eutoctoid defined Solid form converted to two solid form by
using heating and cooling.

Answer / srini

the steels are only eutectoid. (hyper eutectoid and hypo eutectoid). steel cant be formed wen C content is above 2.14%. Hence the steels which have below 0.8% of C are hypo eutectoid steel and steels which have C range of 0.8-2.14% is called hyper eutectoid steels

Answer / ravi

basic difference is that eutectoid steel containsless than
0.8% carbon and eutectic contains greater than 0.8%

Answer / mahendra

eutectoid steel containsless than
0.8% carbon and eutectic contains greater than 0.8%

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.
