Excellent brittle crack propagation stop characteristics of the high-strength structural steel plate and a manufacturing method

The present invention provides a brittle crack suitable for a thickness of 50mm or more vessels of high-strength steel plate and a manufacturing method excellent characteristics with stop structures. A brittle crack arrest thick steel plate superior properties, characterized by having a specific chemical composition, metal structure of ferrite as the main body, a surface layer portion having a thickness RD // integrated intensity of (110) plane is 1.3 or more I , the RD // center of the thickness of the integrated intensity of (110) plane is 1.8 or more I texture Charpy fracture appearance transition temperature (vTrs) of the surface layer portion is -60 deg.] C or less, and the thickness center portion Charpy fracture appearance transition temperature vTrs higher than -50 ℃.
