ASME SA572 Gr. 65 is American Standard V-Nb high strength low alloy structural steel grade. ASME SA572 Gr. 65 steel plates are mainly used in bridges, buildings, electric power industry structure, etc.
ASME SA572 Gr. 65 steel plates require delivery in hot rolling or controlled rolling state. In order to ensure good low temperature impact toughness, BBN steel adopt strict two stage control rolling process to produce SA572 Gr. 65 structural steel plates.
Rough rolling adopt high temperature fast rolling and large pressure reduction, the first two pass reduction >25mm, ensuring the rolling penetration, the repeated deformation of austenite grain, and to make the grain size refined. In the finishing stage, the rolling temperature <950 DEG C, reducing the effect of mixed crystal on the mechanical properties of ASME SA572 Gr. 65 steel plates. The finishing rolling temperature of ASME SA572 Gr. 65 steel plates less than 16mm is 830~860 DEG C, and that of ASME SA572 Gr. 65 steel plates within 16mm to 32mm is 840~870 DEG C.
