USE OF INTERMEDIATE PIECE FOR CONNECTING MOLDED ARTICLES OF MANGANESE STEEL WITH CARBON STEEL, AND METHOD FOR CONNECTING AUSTENITIC MANGANESE STEEL CASTING PIECES WITH STANDARD RAILS

摘要

In an intermediate piece for connecting molded articles of manganese steel with carbon steel, in particular austenitic manganese steel casting frogs with standard rails, the intermediate piece is comprised of steel from the group of austenitic-ferritic duplex steels having a ferrite portion of 60 wt %. The method for connecting austenitic manganese steel castings with standard rails is characterized in that an austenitic-ferritic intermediate piece made of duplex steel comprising 60% ferrite is welded with the manganese steel casting and the standard rail.
