Abstract (en)
The present invention relates to a duplex cast steel having a microstructure comprising 30-50 vol% austenite and 50-70 vol% ferrite, wherein said steel has a composition comprising 0.50-3.40 wt% Ni, 18-27 wt% Cr and up to 0.14 wt% N. By the invention, a duplex steel which is possible to cast and which has low amount of Nickel compared to currently used standard steels is provided. The inventive steel can be used for chemical process equipment, such as process components in the pulp and paper industry, such as pump and agitator components.
