I hope that this forum is meant to be used to ask questions about material properties. I am looking for a material that will be operating in the temperature range of 300-800 deg. F. that will have an expanded metal (.012" thick) rubbing against it with 20-50 lbf . This expanded metal is galvanized and I am having trouble with the galvanizing (Zinc) softening and transferring to the 304 Stainless Steel heater bars (material to be replaced/improved) that it rubs against. The expanded metal moves relatively slowly 2-6 ft./min. and must be in contact with the heater bars for this process. I originally tried 1018 cold rolled steel and that was much worse. The galvanizing operation next to our plant told me that SS was the worst material for them to galvanize (why someone would want to galvanize SS I don't know) so I went to that material and got some improvement. The fact that the 2 metals are in constant sliding contact requires low friction and long wearing attributes for best service. Any help appreciated.
