In addition to other comments, it's also difficult to weld. Stainless steel retains heat, so prolong welding can warp it. Also unless careful, welding can destroy the Chromium coating, so the area are the weld will rust quicker than the bulk material. When choosing a metal material, it's important to consider not just its innate properties, but it properties during join. Welding can melt the metal surrounding the weld, which can undo many heat treatment or mechanical processes previously used to get the material to the desired specs.
