Thanks for the suggestions.
Basically we have a bakers cart, and a tray which weighs approximately 20-30lbs and then we slide the tray onto the bakers cart. http://ecx.images-amazon.com/images/I/41a6DgZrFBL._SY300_.jpg Kind of similar to the link. We see tiny particulates 50 to 200 microns...
I'm trying to reduce the amount of particulates generated by stainless on stainless contact. The steel sees temps of 245C so most plastics are out of the question to reduce friction. What is the best type of finish on steel to lessen the amount of friction and particulate generation with SS on SS?
