Structure And Properties of the Centrifugally Cast High-Alloyed (25Cr35NiNbTi) Steel after Long-Time Operation in Steam Reforming

The paper presents the influence of performance conditions of high-alloyed nickel-chromium cast steel intended for use in steam reforming plants on the morphology and number of phases present in centrifugally cast tubes. Structure identification was done by the methods of light and scanning microsco...
