The B610CF Series high strength(Q&T)steel plate with low susceptibility to welding crack with the

thickness from 12mm to 50mm are successfully developed in December 2005,and it is evaluated

and appraised by the experts organized by the China Standardization Committee on Boilers and

Pressure Vessels(CSCBPV) in June 2006.The B610CF Series with thickness of 12~50mm can be used

to build the spherical tanks or vessels whose service temperature is matched to the temperature

authorized by CSCBPV.The B610F Series steel plates have been used to fabricate the low temperature

spherical tanks with the different volumes for the medium of oxygen gas, nitrogen gas,ethylene, propylene etc.
