摘要：The low temperature tensile properties, Charpy-V notch impact performance and fracture toughness of SA738Gr.B steel plate for domestic CAP1400 containment vessel were tested. Then, the reference temperature T0 of the master curve method was obtained. The fracture toughness distribution of the steel in the whole ductile-brittle transition zone is predicted and its applicability is verified by the theoretical basis of the master curve method. The results show that the reference temperature of SA738Gr.B steel master curve method is-123.6 ℃. The master curve method is appropriate for SA738Gr.B steel with domestic nuclear containment vessel. ? 2019 Trans Tech Publications Ltd, Switzerland.
