Please Help. I am having deep drawn 304 sinks made in China. The material itself seems to pass tough salt spray tests w/o any problems, but at the bottom of the sink, where we stamp out a drain hole, rust forms on the cut edge, and the sink therefore fails salt tests. Is this a result of the stamping-cut process? What can we do to avoid this? We urgently need advise and will be forever gratful for help. Please Help. MartyS

Dear Friend Tha question is too old, however, I may add that cutting of the SS surfaces lack passivity, and hence rusting is promoted by corrosives.
