A High Yield Strength steel for welded and weight – saving structures Bozhong® Ultra 1100 is a quenched and tempered steel for structure with higher strength. Thanks to a minimum yield strength of 1100 N/mm², Bozhong® Ultra 1100 enables to make weight savings or support higher stresses and thus carry higher payload. With a good quality of steel making process, an adapted chemical analysis (low alloying content) and a good manufacturing process (uniform mechanical characteristics), Bozhong®Ultra 1100 is easy to machine, to bend and to weld which simplify production and maintenance. Standards Bozhong® Ultra 1100 is produced as per Industeel technical data sheet.
