Abstract: Diffusion metallic anticorrosive zinc-iron-aluminum coatings of iron and iron-based item surfaces, realized by heating of products at temperatures of 370null450null C. in a saturating powder mixture environment in a closed container. The coating compositions are multiphase-polymetallic, and comprise zinc, iron and aluminum. Other elements may be added to attain specific coating properties. This coating exhibits a high corrosion resistance (at least a 700-hour corrosion resistance level in a standard salt spray test), a relatively high hardness level and good adhesion to secondary coatings.

Abstract: A battery case excellent in glossiness of appearance and working efficiency and a surface-plated steel plate which can be used preferably to manufacture the battery case. The battery case is produced by deep-drawing, DI-forming, DTR-forming a surface-treated steel plate having glossy nickel or glossy nickel-cobalt alloy plating on the outermost layer corresponding to the external face of a battery case of a plated original plate consisting of a steel plate. The glossy nickel plating or glossy nickel-cobalt alloy plating layer on the outermost layer has a high glossiness, and therefore the appearance is excellent. The runnability of a formed battery case is high as well as the working efficiency.

Abstract: Disclosed are a steel plate and a hot-dip galvanized steel plate, superior in terms of high electromagnetic shield capacity. The steel plate is prepared from a composition comprising C, N and S in an amount of 0.150% by weight or less in total; Mn in an amount of 0.1 to 1.0% by weight; Si in an amount of 0.5% by weight or less; Al in an amount of 1.0% by weight or less; P in an amount of 0.06% by weight or less; and Fe for the remainder, and inevitable elements, and shows a yield strength of 18 kg/mm2 or higher, and an elongation of 40% or higher. The hot-dip galvanized steel plate is prepared from a composition comprising C, N and S in an amount of 0.0150% by weight or less in total; Mn in an amount of 0.2 to 0.8% by weight; Al in an amount of 0.6% by weight or less; Si in an amount of 0.4% by weight or less; P in an amount of 0.06% by weight or less, with the proviso that the sum of Mn, Al, Si and P amounts to 0.2null1.0% by weight; and Fe for the remainder, and inevitably present elements. In addition to having high yield strength, the hot-dip galvanized steel plate is resistant to corrosion owing to the coating of a corrosion-resistant element on the surface.

Abstract: A chemically processed steel sheet comprises a steel base coated with an Al-Si alloy plating layer, whose Si content is preferably adjusted to 5-13 mass % as a whole and to 7-80 mass % at a surface, and a converted layer generated on the surface of the plating layer. The converted layer contains both of soluble and scarcely-soluble compounds. The soluble compound such as a manganese oxide or hydroxide or a valve metal fluoride is once dissolved to water in an atmosphere and then re-precipitated as scarcely-soluble compounds at defective parts of the converted layer. The scarcely-soluble compounds act as a barrier for corrosion-prevention of a base steel. Due to the re-precipitation, i.e. self-repairing faculty, excellent corrosion resistance of the converted layer is still maintained even after defects are introduced therein during plastic deformation of the steel sheet.

Abstract: A metallic sheet with an aluminum coating, the coating having an internal layer of iron/aluminum/silicon alloys, and an external layer, thicker, of an aluminum-based phase and secondarily of phases in the form of needies or elongated lamellae. The projection of the length of all needles or lamellae in a direction perpendicular to the plane of the external layer is less than the thickness of this layer. This structure, which is obtained by a thermal treatment of the external layer at a temperature of 570-660null C. notably for less than 15 sec, considerably decreases the risks of cracking.

Abstract: In a chromating solution comprising a water-soluble chromium compound and a reducing agent and in which hexavalent chromium ions produced by dissolution of the water-soluble chromium compound have been partly reduced with the reducing agent to trivalent chromium ions, an oxycarboxylic acid compound is used as the reducing agent. This chromating solution causes neither gelation nor sedimentation of the solution even when hexavalent chromium ions are reduced to trivalent chromium ions at a reduction percentage of more than 50%. The chromating solution and a chromate film formed on a steel sheet may also contain an organic resin, phosphoric acid or a phosphoric acid compound, or a silica sol.

Abstract: A stainless steel/Cu clad which has high-temperature strength enough to be not easily deformed and be sufficiently practical and high thermal conductivity for a high temperature use, and a manufacturing method of such a clad. The stainless steel/Cu clad of the invention is formed by bonding a high Mn austenitic stainless steel containing 9-16 mass % Mn and Cu metallically. Manufacturing of the stainless steel/Cu clad is carried out as follows. That is, a first sheet made of the high Mn austenitic stainless steel, a second sheet made of Cu, and a third sheet of a heat resisting steel which acts as a peeling material are wound in a coil shape in a state where they are laminated in such order and, subsequently, the obtained coil is vacuum-annealed, thereby bonding them and manufacturing the high Mn austenitic stainless steel/Cu clad having high-temperature strength and high-thermal conductivity.

Abstract: A method of coating of steel products such as plate and sheet using an aluminum-zinc coating alloy includes modifying the coating bath with a particulate compound constituent in effective amounts to control the spangle facet size of the coated product, improve tension bend rust stain performance, and improve coated product paintability. Constituents include borides such as titanium boride and aluminum borides, carbides such as titanium carbide, and aluminides such as titanium aluminide. The method produces a coated steel product that does not require temper rolling for painting.
