SA738GrA steel plate itself has some high-quality properties such as high strength, high toughness, corrosion resistance, radiation resistance, wear resistance, weather resistance, impact resistance, and low temperature resistance.

ASME-SA738Gr.B steel is used as a manufacturing material for containment, this kind of steel is a low-alloy high-strength steel, and the welding performance is good, but because of the presence of Cr, Mo and other elements, if the welding process is not appropriate during the welding process, there is a risk of embrittlement, thermal strain embrittlement and welding cracks in the heat-affected zone of the welded joint.
