Description

Material X2CrNi12 (former: X 2 Cr 11) is also contained in SEW 400 : 1997-02 (here for tempered condition, in DIN EN 10088 for annealed condition). This material is a ferritic steel showing considerably higher corrosion resistance than general construction steels. It is more cost-efficient than high-alloyed stainless steels. Its corrosion resistance is comparable to 13 per cent Cr-steels. X2CrNi12 is unsuitable for higher corrosion loading. The steel shows high static and dynamic strength values, ease of processing as well as sufficient corrosion resistance and good abrasion resistance. Application in traffic/transport, in agricultural and conveyor technology as well as in building industry for scaffolds or facade elements. No resistance to intercrystalline corrosion both in delivery and welded condition.
