The method includes the step of effecting a galvanization on a steel sheet followed by an alloying treatment. The sheet of galvanized steel is immersed in a bath of an aqueous solution containing 0.1 wt % or more of borate of an alkali metal, and then taking the steel sheet out of the bath and effecting such control as to make the amount of deposition of the water-containing borate film on the steel sheet surface to range from 10 to 1,000 mg/m.sup.2, and then heating the steel sheet at a temperature ranging from 60.degree. to 400.degree. C. Thereafter, the steel sheet is cooled to a normal temperature.

摘要： In connection with a process of implementing galvanizing and galvannealing on steel strips containing highly oxidizable elements such as Si, Mn, P, Ti, Nb, Al, Ni, Cu, Mo, V, Cr, and B, after annealing in a continuous line or implementing electroplating after annealing, the present invention provides a method for restraining non-plating at low cost in a stable manner and a surface treated steel strip having minimal non-plating. By applying on at least one surface of a steel strip a Fe plating having a coating weight of 0.1-10 g/m.sup.2 and an oxygen content of 0.1-10 wt %, followed by annealing and then zinc or zinc alloy plating, there is obtained a surface treated steel strip having minimal plating defects which includes a Fe plating layer immediately below a zinc or zinc alloy plating layer and a steel alloying element concentrated stratum immediately below the Fe plating layer. The Fe plating may be formed using an electroplating bath which contains 0.1-10 g/l of Fe.sup.3+ and a carboxylic acid or an alkali metal salt thereof.

Also provided is a bake hardenable, surface treated aluminum alloy sheet having improved formability, an elongation of at least 25%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising a bake hardenable aluminum alloy substrate containing Mg and Si in an amount of at least 0.4 wt % calculated as Mg.sub.2 Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m.sup.2. By forming a zincate layer as an undercoat below the Fe rich plating layer, the plating adhesion is further improved. The preferred Fe rich plating layer is a Fe-Zn alloy plating layer containing 20 to 80 wt % of Zn for corrosion resistance improvement. A Fe-Zn alloy plating layer containing 30 to 40 wt % of Zn meets both formability and corrosion resistance.

摘要： A steel sheet containing C: 0.0005% or more and 0.0035% or less, Si: 0.05% or less, Mn: 0.1% or more and 0.6% or less, P: 0.02% or less, S: less than 0.02%, Al: 0.01% or more and less than 0.10%, N: 0.0030% or less, B: 0.0010% or more, in which the relationship B/N≤3.0 is satisfied and the balance being Fe and inevitable impurities, and a microstructure in which the average integrated intensity f in the (111)[1-10] to (111)[-1-12] orientations on a plane parallel to a sheet surface at a position located at ¼ of the thickness of the steel sheet is 7.0 or more, in which an average ferrite grain size is 6.0 μm or more and 10.0 μm or less, and the relationships EAVE≥215 GPa, E0≥210 GPa, E45≥210 GPa, E90≥210 GPa, and −0.4≤Δr≤0.4 are satisfied.
