The RobuSal®800 air-hardening steel grade from Salzgitter Flachstahl has been developed especially for automobile manufacturing. In delivery condition, air-hardening steels are soft and therefore easy to form into complex components and they have high strength as a finished component. RobuSal®800 can be welded either manually or mechanically using all electrical welding techniques, in accordance with the general technical rules.
