A203 Grade F STEEL PLATE

Comparing with other boiler steel grades in ASTM A203/A203M,A203 Grade F,A203GrF steel plate,A203GrF steel sheet owned a higher yield strength above 380 Mpa for plates thickness equal and belows 50 millimeters,and tensile strength above 550 Mpa.Else the heat treatment for pressure vessel A203 Grade F steel plate  have to be done under Quenching and tempering if customers have no other special requirement when enquiry and ordering.Now Xinsteel can roll the maximum thickness for boiler steel plate A203 Grade F can reach to 300 millimeters.
