EFFECTS OF COMPOSITION ON HEAT-AFFECTED-ZONE CRACKING OF NI-CR-MO STEEL WELDMENTS-I.
Abstract
Because cracking problems were encountered during the welding of the first HY-80 steel submarine hulls, the program to develop an HY-130/150 submarine-hull weldment was designed to include a comprehensive investigation of the composition limits within which an HY-130/150 steel will exhibit minimum susceptibility to weld-heataffected-zone cracking. Therefore, a statistically designed program was initiated to determine the effects of carbon (0.05 to 0.21%), manganese (0.30 to 1.50%), phosphorus (0.003 to 0.027%), sulfur (0.003 to 0.027%), and nickel (1.00 to 9.00%) on the weld-heat-affected-zone cracking of Laboratory cruciform specimens fabricated from 32 experimental Ni-Cr-Mo steels (1.3% Cr and 0.6% Mo).
