Hofmann, P J; Friedrich, B C

In order to identify suitable alternative materials for cobalt-base alloys used as hardfacing material for nuclear valves, three corrosion and wear-resistant iron-base alloys were investigated. In detail, comparisons were performed between Everit 50, Antinit DUR 300, Cenium Z 20 and Stellite 6 as to metallurgy, manufacturing properties, corrosive properties in simulated PWR and BWR coolant ( under no-flow and high-flow conditions with and without contamination), tribological properties (at different temperatures, contact pressure levels and for different material combinations) and mechanical properties. Data are given on suitable heat treatment, welding parameters and areas of application for each alloy under consideration. 24 refs., 87 figs., 4 tabs.
