60 watts bulb and resistor home heater is connected in
series and 230v is given to the circuit. The heater is
giving some amount of heat. If instant of 60 watts bulb
replace 100 watts bulb what will be the output of the heater?

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.
