Stainless steel is harder than aluminum, but also much heavier. It is basically steel with a high (11% and higher) chromium content. There are a variety of types of stainless steel with different surface treatments from matte to high gloss. It is not a coating, so it will not peel or flake off. Most types of stainless steel are not magnetic but some are, so a magnet test is not definitive. Stainless does not transmit heat as well aluminum and therefore is not as effective in carrying heat away from a LED.
