Abstract: 
The object of this contribution is to provide engineers with an appreciation of the corrosion protection process of stainless steel embedded in concrete. Discussed main focuses are the influence of the steel type, the presence of welds, of the chloride content and of carbonation. The resistance to galvanic corrosion (contact with carbon steel) and cost aspects are also treated. The results consider laboratory tests, field tests and practical experiences. In conclusion, one can say that ferritic stainless steel with at least 12 mass-% of chromium might be the best choice in moderately aggressive environments (carbonated concrete or concrete exposed to low chloride levels). Austenitic stainless steel of type CrNiMo 17-12-2 and ferritic-austenitic (duplex) steel CrNiMoN 22-5-3, even in the welded state, proved to give excellent performance in chloride-containing concrete, even at the highest chloride levels that appear in practice.
