Thick-walled pipe blanks made by centrifugal casting of corrosion-resistant 08X18H10T steel are investigated. These blanks are intended for subsequent hot pressing of pipe (diameter 89 mm, wall thickness 12 mm). The macrostructure of the castings is studied, as well as the mechanical properties of cast and heat-treated tangential, transverse, and longitudinal samples. The defects observed in the centrifugally cast pipe are analyzed. The resistance of the cast metal to deformation is assessed, as well as the technological plasticity of the cast pipe blank. © 2011 Allerton Press, Inc.

The solidification of large ingots is simulated, and the results are confirmed in experiments. The application of cold-tapped direct-taper ingots is found to increase the ingot-to-product yield by 7% for the production of hollow billets and to decrease the degree of segregation heterogeneity in an ingot. The total carbon segregation in a cold-tapped ingot is three times lower than that in a comparative ingot. © 2010 Pleiades Publishing, Ltd.
