摘要：
This invention relates to a steel sheet provided with a sacrificial cathodic protection layer comprising from 5 to 50% zinc by weight, from 0.1 to 15% silicon by weight and optionally up to 10% magnesium by weight and up to 0.3% by weight, in cumulative content, of additional elements, and also comprising a protection elements to be selected from among tin in a percentage by weight between 0.1 and 5%, indium in a percentage by weight between 0.01 and 0.5% and combinations thereof, the balance consisting of aluminum and residual elements or unavoidable impurities. The invention further relates to a method for the fabrication of parts by hot or cold stamping and the parts that can be thereby obtained.
