METHOD FOR HOT DIP GALVANISING OF AHSS OR UHSS STRIP MATERIAL, AND SUCH MATERIAL

摘要

The invention relates to a method for hot dip galvanising of advanced high strength or ultra high strength steel strip material, such as dual phase steel, transformation induced plasticity steel, transformation induced plasticity assisted dual phase steel and twinning induced plasticity steel strip material. According to the invention, the strip material is pickled and thereafter heated to a temperature below the continuous annealing temperature before the strip material is hot dip galvanised.
