The SA738 Gr.B high strength Q&T steel plate is successfully developed in 2006 and can be used to 

manufacture the Containment Vessel in the 3rdgeneration AP-1000 Nuclear Power Station. Under

the delivery of quenched and tempered, and simulated post weld heat treatment, the steel plate

can meet relative requirements of ASME SA738Gr.B or ASTM A738 Gr.B,and also fulfill the relative

requirements in the Sectionand Sectionof ASTM Boiler and Pressure Vessel Code, as well as 

Class MC Components. Subsection NE, the steel plate also has good toughness at lowest to minus

45. Currently the available thickness is from 10mm to 100mm.
