Query: Beware: French Countryside 18/0 Inferior Stainless Steel

Just bought Mikasa French Countryside set of 20 at Tuesday Morning and the flatware is stamped 18/0. Mikasa changed to a cheaper grade of steel. 18/0 will not maintain luster. The Mikasa box advertizes 18% chromium, but the 10% nickel that you would expect is NOT listed.
