Description

The make X3CrNiMo13-4 is comparable to X 4 CrNi 13 4 acc. to SEW 400: 1991-02. The steel shows at temperatures of -60 to 300 °C favorable ductility properties and sufficient corrosion resistance. Better corrosion qualities than comparable 13% Cr-steels due to the Ni-content. Application in tempered condition for turbine blade wheels, pumps, compressors, components of power plant and reactor construction as well as in shipbuilding.
