inquiry
Material :
J93402
The best method to produce CH20 (309) heavy wall seamless steel tubes with different diameters is centrifugal casting. 
You do not need to purchase the solid bars then do the drilling process. Centrifugal casting makes you save materials and machining fees. 
The mechanical properties of centrifugal casting are almost equal to forgings and zero porosity is one of the features of centrifugal casting much different from the traditional casting.
