The saw blade is stainless steel and performed very well. The frame is not stainless as far as I can tell. The one thing that was not provided was an MSDS for the protective coating on the blade as it is shipped. It took a fair amount of cleaning with several solvent tests to clean it and the slots in the frame and the holes in the spring pins in the blade. When you clean the blade do not be surprised to see one side of the spring pins shiny while the other is still blued.
