Steel 08Kh18N10T deformation resistance under hot upsetting conditions is studied in the Gleeble-3800 research unit. The test material is two batches of cylindrical specimens 8 mm in diameter and 12 mm high, cut from a centrifugally-cast pipe billet in longitudinal and transverse directions. It is shown that with a high strain rate (10 sec-1) in the region of high strains transverse specimens have a higher strengthening factor compared with longitudinal specimens. © 2013 Springer Science+Business Media New York.
