Centrifugal Cast Iron Hollow Bar

Centrifugal Cast Iron Hollow Bar « Products « Home

 

We are among the leading Cast Iron Hollow Bar Manufacturers. We have expertise in Casting Ductile and grey Iron. The main quality characteristic of Centrifugal Cast Iron Hollow Bar 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.
