AcaSal®700+Z and AcalSal®700 StronSal® is a high strength steel based on grade S700MC thermomechanically hot-rolled strip, which is hot-dipped zinc-coated. It features a very high yield strength and tensile strength with sufficiently high expansion for cold forming processes.

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.

Customer's benefit:

AcaSal®700 with zinc coating or StronSal® coating is very well weldable.

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)
  • rail car construction



  • Yield strength Rp0,2/ReL (in MPa): ≥ 700
  • Tensile strength Rm (in MPa): 750 - 950
  • Elongation A80 (in %): ≥ 10
  • Zinc coating: Z100 to Z275
  • StronSal® Coating: ZM70 to ZM200
