Measurement and Analysis on SH-CCT Curves of SA738Gr.B Steel for Steel Container of Nuclear Power Station
The simulated HAZ continuous cooling transformation(SH-CCT) curves of SA738Gr.B steel for steel container of nuclear power station were measured by Gleeble-3500 thermal mechanical simulator according to the method of expansion.The effects of phase transformation microstructure and vickers hardness with different continuous cooling transformation curves were analyzed.The SH-CCT curves research of SA738Gr.B steel can provide the correct theory formulation to its welding technology.
