Abstract: In structural engineering connection elements for ventilated curtain walls and suspended ceilings are more and more made of stainless steel due to reasons of corrosion protection. A special approval process regulates the use of the steel grade in Germany.
The permitted stainless steels for substructures, connectors, fastenings, hangers and anchorage devices are defined in dependence of environmental conditions and installation. Normally austenitic Cr-Ni-(Mo)-steels are applied. The use of hardened martensitic steels for self-drilling screws and concrete screws should be desirable but such fasteners are not sufficient sure. In strong acid and/or chloride containing environment (see-atmosphere, de-icing salt) connection elements might be endangered by pitting corrosion, crevice corrosion and stress corrosion cracking, if these products are made of unsuited alloys. In the contribution the corrosion situations are described in detail. Further typical corrosion damages are discussed if unsuited stainless steel products are applied.
