I think Woodcraft sells the replacements as well as the new scrapers. You can also get the steel from any company that sells sheet metal. My guess is that it is regular cold rolled sheet steel, but it might be something weird like spring steel. All you need is a rectangle the right size. I'm assuming that you know how to put the burr on the scraper; if you don't it isn't hard to learn how to do, just look in any good woodworking book. P.S Depending on the tolerances involved, you will either need to make an educated guess on the thickness of the metal, or find someone who has an iron and measure it with a micrometer.
