Abstract: front page image
(EN)A cold-rolled low-density steel plate having excellent phosphorization performance. An iron particle layer is disposed on the surface of the cold-rolled low-density steel plate, and dispersed iron particles exist in the iron particle layer. The cold-rolled low-density steel plate comprises 3.0% to 7.0% of Al element by mass percentage.
(FR)Cette invention concerne une tôle d'acier faible densité laminée à froid ayant d'excellentes performances de phosphorisation. Une couche de particules de fer est disposée sur la surface de la tôle d'acier faible densité laminée à froid, et des particules de fer dispersées sont présentes dans la couche de particules de fer. La tôle d'acier faible densité laminée à froid comprend de 3,0 à 7,0 % d'Al en pourcentage en masse.
