ONE-SIDE ALUMINIZED STEEL SHEET DEVELOPMENT AND PROPERTIES OF A NEW ANTI-CORROSION MATERIAL

Nisshin Steel Co., Ltd. has developed a new process for the production of a "one-side aluminized steel sheet". The process utilizes a double layer one-side "stop-off" coating to prevent the molten Al from adhering to the steel surface. The "Stop-off" coating is removed by simple mechanical brushing after hot dipping. The characteristics of this product by above mentioned process are: 1) The steel side was as clean as a conventional cold rolled surface and showed no trace of the "stop-off" layer. Thereby, phosphating and ED painting were performed. 2) In the salt spray test data was obtained from zinc and Al coated steel surfaces; the coatings on both surfaces being of equal thickness. The length of time it took to corrode 30% of the samples' surface was determined and it was found that the Al surface lasted three times longer than the zinc surface. 3) By selecting the lapping type weld condition, after 5,000 spot welds the one-side Aluminized steel sheet did not show a drop in shear strength.
