These Guidelines were specifically developed and published by China Register to govern the application of the high strength steels used for construction of the large ship hulls, having the yield stress of 460 N/mm2 or more. Brittle fractures can occur in structures made of extra thick higher strength steels. The present document provides measures to be implemented for prevention of the brittle fractures in such materials.

The content is arranged in five major section with the first one being introductory and providing general information, purpose of the guidelines, terms and definition, application and tests. Four chapters of the main body of the guidelines cover the approval and inspection of the H47 steel plates, brittle crack arrest steels - their application and inspection, and application of the extra thick high strength steels on container vessels.

There are three appendices at the end of the publication, providing necessary information about the standard ESSO tests, double tension tests and specimens that are normally used for the H47 steel approval tests. A needful reference source for people engaged in construction of ship hulls where the high strength steels of extreme thicknesses is utilized.
