Grafting for coupling a piece of manganese steel to another piece of carbon steel, process for coupling with this graft, and binding obtained by this procedure.

摘要

The intermediate member of this invention is obtained by casting an austenoferritic alloy which has the following chemical composition (% by weight): … Carbon .... 0.025-0.035% Manganese .... 6-11% Silicon .... 0.5-1.5% Nickel .... 5-8% Chromium .... 17.5-20% Molybdenum .... 0.5% Nitrogen .... 0.12-0.20% Phosphorus and sulphur .... /= 0.030% … and in which the delta ferrite content measured by counting is between approximately 5 and 15%. …??This intermediate member applies especially to the connection of a track part made of manganese steel to other parts made of carbon steel, such as railway rails. …IMAGE…
