HISTAR® Innovative high strength steels
HISTAR steels are structural grades with a low alloy content, combining high strength, good toughness and superior weldability. In this brochure you can find information to guide you towards choosing the appropriate steel grades and using their full potential, thus creating the best conditions for a contemporary, economical, ecological and consistent sustainable construction.
With the development of the HISTAR steels, ArcelorMittal has succeeded to create structural steels combining high yield strength with excellent toughness at low temperatures and outstanding weldability. These material properties were considered incompatible until now.
This development was made possible by the innovative “in line” Quenching and Self- Tempering (QST) process, developed by the Commercial Sections division of ArcelorMittal in cooperation with the Centre de Recherches Métallurgiques in Liège.
The QST process enables the costeffective production of high-strength steels. HISTAR steels are in full compliance with European and national standards.
Hot rolled H-beams in HISTAR grades enable the construction of innovative and competitive structures. Engineers take full advantage of the excellent HISTAR properties when designing gravity columns of high-rise buildings, longspan trusses and offshore structures. Furthermore, the new steels are recommended in case of stress governed as well as seismic design.
With HISTAR, ArcelorMittal satisfies the needs of the designers for light and economical structures which fulfil at the same time the criteria of safety and sustainability.
