High Strength (690MPa)
Bozhong 690 grades are high yield strength steels for welded and weight – saving structures

Weight saving
Thanks to its minimum yield strength of 690 MPa, it enables to save weight in the final stucture.
Easy forming and weldability
Thanks to its exceptional purity rate (very low sulphur and phosphorus contents), and its adapted chemical analysis, Bozhong 690 is easy to shape and weld, even for heavy and thick plates. The reduced carbon and alloying elements content of Bozhong 690 allows welding in very good conditions with excellent characteristics.
