Piston rings are made of steel. They have to be hard so there is chrome in them (almost stainless!) but not hard enough to score the cylinder walls, and must be flexible to "hug" the cylinder walls to make a good compressions seal. You may want to Google this question to get a better idea of some of the materials used.
Stainless steel rings are never used for any type of body decoration. Stainless steel is used for jewelry and watches because it will not oxidize or turn black.
In earlier years (1900) pans were made from copper, if you were wealthy enough, while for poorer folk their pans were made of cast iron or tin plate. Then along came steel pans covered with porcelain, a hard and smooth surface which was easy to clean. Later came aluminium pans and stainless steel ones. The latest development is for pans which have good conductive materials on their bases. Also the bases are carefully ground flat so that they can be used on gas rings, or electrically powered rings or surfaces which have the rings set into a hard porcelain surface.
