Abstract (en)
[origin: EP2933347A1] This steel plate contains predetermined steel chemical compositions and has a Di value of 2.5 or more, where the Di value is defined by the steel chemical compositions. The steel plate includes a retained austenite phase (retained ³) existing at -196°C in a volume fraction of 2.0% to 12.0% and has a retained austenite stabilization parameter of 3.1 or more, where the parameter is defined by chemical compositions contained in the retained austenite existing at -196°C.
