What metal would be better suited for heat transfer, reliability, and cost...??? I'm currently using Aluminum for a 'hot-wedge'.
3 6110i m going to give an interview for iocl on 5th aug . pls tell me what questions can be answered from metallurgical prospect
IOCL,
2967I 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.
2389any input on how to spec out(if possible) a larger grain structure(3/8" or larger) on a Al 6061 forging material.

Is there any way through hardening and anodizing some type of aluminum, it could be as hard as steel? I have hardened steel rollers that run up and down on a ramp along with spring pressure. Alternatively, if you are familiar with snowmobiles, the rollers run on the helix on the secondary clutch.
