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, welded to a bainitic steel member, including boron up to 0.01% by wt, molybdenum 0.2 to 3% by wt, manganese 0.3 to 3% by wt, with the weld subsequently tempered to provide enhanced fatigue resistance by a post welding heat treatment. |
