INTERMEDIATE MEMBER FOR CONNECTING A PART MADE FROM MANGANESE STEEL TO A PART MADE FROM CARBON STEEL, PROCESS FOR CONNECTING THESE MATERIALS USING THIS INTERMEDIATE MEMBER AND ASSEMBLY OBTAINED BY THIS PROCESS

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 .... 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. ……
