Abstract

Tools for working hot metal under conditions involving heavy shock and rubbing contact under high pressure, such as plugs for plug-rolling tubes, billet guides for tube-piercing mills, and pipe balls, are made from an iron-chromium-nickel alloy containing about 24 per cent of chromium, 10 per cent of nickel, and 1 per cent of carbon. Up to about 2,5 per cent of silicon and 1,5 per cent of manganese may be present, and also small amounts of tungsten and vanadium. Specifications 13414/13, 13415/13, 129,330, 232,656, 236,931, 287,876, 297,045, and 314,176, [all in Class 82 (i), Metals, Extracting &c.], are referred to.
