This report discusses some of the pertinent factors, especially banding and homogenization, which influence the susceptibility of HTS hull steel to underbead weld cracking. The use of laboratory heats for evaluating various chemical compositions and deoxidation practices is considered. The specific items covered are as follow: (1) The influence of time and temperature upon the homogenization of both average and high chemical composition HTS steels. (2) The effect of various degrees of homogenization upon underbead cracking and tensile properties. (3) The effect of hot reduction upon the response to homogenizing treatments. (4) The demonstration of the mechanism of banding in HTS hull steels. (5) A study of the underbead cracking characteristics of quenched and drawn HTS having a yield strength above 75,000 p.s.i. (6) A comparison of the underbead cracking characteristics and mechanical properties of laboratory and commercial HTS hull steels. (Author)
