摘要：

A YP460 N/mm(2) class steel plate with a thickness of up to 100 mm for ultra-large container carriers has been developed by thermo-mechanical control process (TMCP). The developed YP460 steel plate has an excellent brittle crack arrest toughness of over 11,000 N/mm(3/2). The characteristics of the plate include a highly oriented texture and excellent Charpy impact toughness by means of an advanced TMCP for the prevention of brittle crack propagation. The alloy design of the plate is a relatively high carbon equivalent to satisfy the required tensile properties; however, good weldability is achieved as a result of its low weld cracking parameter alloy design.
