Abstract : Because of various processing difficulties and a high rejection rate encountered in the early commercialization of heat-treatable dual-hardness steel armor, extensive studies were made to solve these problems. The process-technology study describes work culminating in the minimization of decarburization, elimination of surface grinding, cutting of plates without edge cracking, and elimination of quench cracking.
