Title (EN) RUSTPROOF STEEL SHEET EXCELLENT IN VARIOUS CHARACTERISTICS INCLUDING CORROSION RESISTANCE
(FR) TOLE EN ACIER RESISTANT A LA ROUILLE ET PRESENTANT DES CARACTERISTIQUES AMELIOREES Y COMPRIS LA RESISTANCE A LA CORROSION
Abstract: front page image
(EN)A Zn-Cr plated steel sheet which is excellent in corrosion resistance and has a phase structure containing heretofore unknown phases $g(h)x, $g(d)x and $g(t)x. The following charateristics (1) to (6) are exhibited by one or a combination of these phases: (1) $g(h)x resistance to surface rusting; (2) $g(t)x moldability; (3) $g(h)x+$g(d)x chipping resistance; (4) $g(h)x+$g(t)x corrosion resistance after working; (5) $g(d)x+$g(t)x secondary adhesion in warm water; (6) $g(h)x+$g(d)x+$g(t)x resistance to pitting corrosion, $g(h)x: hexagonal, a = 2.66 $m(K) 2.74 Å, c = 4.61 $m(K) 4.95 Å, $g(d)x: hexagonal, a = 2.72 $m(K) 2.78 Å, c = 4.43 $m(K) 4.60 Å, $g(t)x: cubic, a = 3.00 $m(K) 3.06 Å.
(FR)Tôle en acier à placage de Zn-Cr présentant d'excellentes caractéristiques de résistance à la corrosion et possédant une structure de phase contenant des phases $g(h)x, $g(d)x et $g(t)x inconnues jusqu'à maintenant. Les caractéristiques suivantes (1) à (6) sont démontrées par une ou plusieurs desdites phases: (1) $g(h)x résistance à la corrosion de surface par la rouille; (2) $g(t)x aptitude au moulage; (3) $g(h)x+$g(d)x résistance aux entailles; (4) $g(h)x+$g(t)x résistance à la corrosion après usinage; (5) $g(d)x+$g(t)x adhérence secondaire dans de l'eau chaude; (6) $g(h)x+$g(d)x+$g(t)x résistance à la corrosion par piqûres; $g(h)x: hexagonal, a = 2,66 $m(K) 2,74 Å, c = 4,61 $m(K) 4,95 Å, $g(d)x: hexagonal, a = 2,72 $m(K) 2,78 Å, c = 4,43 $m(K) 4,60 Å, $g(t)x: cubique, a = 3,00 $m(K) 3,06 Å.
