General:

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.


Highlights:

Function enhancement

Weight reduction


Customer's benefit:

  • innovative alternative to high and ultra high strength steels and aluminum due to greater strength in the hardened and tempered state
  • superior structural durability on welded component due to air-hardened characteristics
  • very good forming characteristics with high component strength
