A weldable austenitic manganese steel joint for railways comprising an austenitic manganese steel member, including manganese 11.5 to 19% by wt, carbon 0.6 to 0.95% by wt, secured by a first weld to a bainitic steel insert, including boron up to 0.01% by wt, molybdenum 0.2 to 3% by wt, manganese 0.3 to 3% by wt, and of relatively short length secured by a second weld to a pearlitic steel member, with heat from the second weld being transferred via the insert to the first weld thereby tempering the first weld. |
