BS700MC

BS700MC Shanghai Baosteel developed a special high-strength cold-rolled steel sheet forming. BS700MC often called high-strength steel, also known as steel boom. Mainly used for large vehicle crane girders, etc.

BS700MC than conventional steels large increases in yield strength, but also has good elongation property, cold bending properties, weldability and impact resistance.

BS700MC steel size :
Thickness : 2.5-14mm
Width : 850-1600mm
Length : 2000-12000

BS700MC Delivery status: BS series adopt high-strength steel-rolled (TMCP) delivery.

BS700MC steels sheet are featured :
1 . Good formability. All grades of BS steel can be cold formed.
2 . Excellent welding performance. The steels have low welding crack sensitivity and the properties of welding joint are good.
3 . Good toughness at low temperature.
