Filter housing could be made of stainless steel, but other materials could be used as well. However, that has little or nothing to do with oil filtration, unless there are some extreme environmental conditions present.
Filters should be chosen by the application and its intended purpose. This info should be known in order to determine the most suitable type of filtration technology (mechanical vs. electrostatic separation). In case a mechanical separation is preferred, one can select proper filter media and its type (depth or surface, preferred absorbency or adsorbency characteristics), size of the filter, its positioning (in-line vs. off-line), oil flow, capability to meet certain target cleanliness, its efficiency and dirt holding capacity. In majority of situations, the last thing to worry about is the material housing is built from.
I think he is referring to washable stainless steel filters. There are several on the market that have a 40 micron or so screen that can be removed, inspected, and cleaned before re-inserting.

yes i use k&p engineering's filter and they make them for other companies..they filter 35u absolute..flows 57gpm the total filter..media is a stainless steel mesh and very easy to clean.media is 37 sq ins.
They manufacture and maintain a ton of wire mesh here in the United States and specialize in some of the specs that you all require. Another source is always a good thing to cut costs and get the best quality products in your hands.
Guys, refer the John's post. it's not a filter, stainless steel cannot filter it's just for keeping nuts, bolts and seaguls out, not for filtration that would be effective for prolonging the life of machinery. An effective filter has to filter below the lubrication film thickness or there will be contaminates larger than the lube film thickness remaining that if hard will cause abnormal wear. An example is putting a 40µm breather filter on a gearbox where the oil film is less than 1 µm, won't work. Check out the down load info on www.rttech.com.au on the dust storm for what has to be removed from lubricants. Regards Rob S
