AcaSal®700: Hot-rolled high-strength TM steel with hot-dipped zinc coating
16.11.2016 | Salzgitter Flachstahl GmbH
The AcaSal®700 steel grade is a high strength steel based on thermomechanically rolled strip. It features a very high yield strength and tensile strength, with sufficiently high expansion for cold forming processes. These products are suitable for cold bending, folding, cold flanging or cold bordering without crack formation.
The new brand from Salzgitter Flachstahl is named after the acacia, whose wood displays enormous resistance. The wood is furthermore not only hard and robust, it is also very elastic and very suitable for processing. AcaSal®, the new steel from Salzgitter Flachstahl, also offers these characteristics.
Salzgitter Flachstahl is currently manufacturing AcaSal®700 in thicknesses from 2.0 to 2.5 mm and in widths from 900 to 1,300 mm. The thickness of the zinc coating is in the range of 100 g/m² to 275 g/m².
The AcaSal®700 microstructure typically consists of bainite. Occasionally there can be minimum content of other phases (e.g., martensite, ferrite).
AcaSal®700 is suitable for welding and displays high formability during roll forming.
Typical applications to utilize the high strength potential combined with weight savings in the component are vehicle construction, longitudinal beams and cross-members in trucks and trailers, safety parts in cars (crash tubes), and rail car construction. This steel grade is used for cold-formed components in a very wide range of structures. It is used particularly to manufacture:
- Longitudinal beams
- Frame structures
- Cold-pressed parts
- Cold-rolled sections
- Structural tubes
Delivery is based on the provisions of DIN EN 10149-2 in combination with the DIN EN 10143 dimensioning standard (hot-rolled strip basis) or on special delivery.
