For the same part, it is possible to Specify the two
different type of Hardness with same scall(EX-Quenching and
tempering==>450 to 500HV30 & Hardening and Austempering 330-
what is No.1 Laathing Scrap Bundle ( Mill Scrap )
WHAT IS THE ACTUAL DEFINATION OF PLANET?
What is chemical composition and mechanical properties of
IS 2004,Gr-3 and IS 305 AB-2?
what are different grades of mild steel available for making
machine structure (housing)
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.
