Abstract
Method of manufacturing steel components containing 12 to 14% by weight of manganese having an austenitic structure, said parts being provided with steel end pieces having a mainly austenitic structure permitting their junction by welding to components made of any desired alloy, wherein, before applying thermal treatment, said end pieces are cast into moulds disposed directly at the ends of said manganese steel components. The ends of the manganese steel component are shaped and the end pieces are subsequently cast thereon in such a manner that each end of the part comprises a front surface inclined about a transverse horizontal axis.
