A High Yield Strength steel for welded and weight – saving structures

Bozhong® Ultra 960 is a quenched and tempered steel for structure with higher strength. Thanks to a minimum yield strength of 960 N/mm² (140 ksi), Bozhong® Ultra 960 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 an excellent precision in our fabrication process (thickness tolerance, uniform mechanical characteristics), Bozhong® Ultra 960 is easy to machine, to bend and to weld which simplify production and maintenance.

By using Bozhong® Ultra 960 and thus thinner plate in welded structures, you limit preheating conditions, you decrease quantity of consumables, welding time and so production costs.

Standards
Bozhong® Ultra 960 fulfills the requirements of S960QL according to EN 10025-6 standard, last edition.
