The main quality characteristic of centrifugally cast material is the high standard of soundness arising from the conditions of feeding and is the predominant factor in the improvement of properties relative to statically cast material. Properties of Centrifugal castings compare favourably with forgings and other wrought products.
Mechanical properties of centrifugal castings are far superior to traditional sand castings due to the considerably finer grain structure and graphite form associated with rapid cooling rates and pressure gradients.
Service life of a centrifugally cast product is improved due to the uniform fine grain structure and the even distribution of very fine pearlite and graphite at any radial distance.
