EFFECT OF CHROMIUM CONTENT ON THE WELD-HEAT-AFFECTED-ZONE TOUGHNESS AND TRANSFORMATION CHARACTERISTICS OF 5NI-CR-MO-V STEELS.
Abstract
The effect of variations in composition on the base-metal properties of ten 5Ni-Cr-Mo steels was investigated, and three of the ten steels, containing 0.5, 1.0 and 1.5% chromium, were evaluated to determine the effect of chromium on the toughness, transformation characteristics, and crack susceptibility of their simulated weld-heat-affected zones. The results showed that over the full range of practical welding conditions, the energy absorption of the various regions in the simulated weld-heat-affected zones of the three steels was high and ranged from 60 to 125 ft-lb at +80 F. In addition, the formation of fully martensitic microstructures in the simulated weld-heat-affected zones indicated that the three steels had sufficient hardenability for all practical welding conditions.
