BS600MCK4 Delivery status: BS series adopt high-strength steel-rolled (TMCP) delivery.

BS600MCK4 steels 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.
