In the pulp and paper industry there are very high requirements for the materials used, e. g. due to bleaching processes. Nickel alloys like C-276, Alloy 59, C2000 etc. are applied in this case. Duplex and superduplex are also quite often used for reactors. KÖNIG + CO. has many years of experience in the processing of these special alloys and has been supplying a wide variety of heads for such vessel plants and apparatus of the pulp and paper industry.
