摘要： The present invention provides a hot-dip Al-plated steel sheet for fuel tanks excellent in air-tightness after welding and corrosion resistance subsequent to forming. The present invention provides, as concrete means, a hot-dip Al-plated steel sheet comprising a steel sheet comprising up to 0.003% of C, up to 0.03% of Si, up to 0.3% of Mn, up to 0.02% of P, up to 0.006% of N, up to 0.1% of Ti, Ti and Nb in a total amount of at least the atomic equivalent of (C+N) and up to 0.2%, 1 to 30 ppm of B, and the balance Fe and unavoidable impurities, and a plating layer comprising 2 to 13% of Si, and the balance Al and unavoidable impurities on the surface of the steel sheet, the steel sheet showing a total elongation of at least 45% after plating. Alternately, the hot-dip Al-plated steel sheet may have a chromate coating in an amount of 5 to 100 mg/m2 on the surface, and it may also have a resin coating on the top surface. As a result, the Al-plated steel sheet is excellent in elongation after Al plating. The Al-plated steel sheet is, therefore, significantly excellent in corrosion resistance subsequent to forming in the internal environment of fuel tanks compared with conventional steel sheets. Accordingly, the Al-plated steel sheet also having excellent air-tightness after welding is most appropriate as a material for fuel tanks of automobiles.

摘要： Method for subdividing the magnetic domains of a grain-oriented electrical steel sheet is improved so that the watt loss can be further lessened and the watt-loss improving effect does not disappear during stress relief annealing. An intrudable means is formed on the finishing-annealed steel sheet on or in the vicinity of strain which promotes the intrusion of an intrudable means. Sb or Sb containing material is a preferred intrudable means and the laser irradiation is a preferred method for imparting the strain and also for attaining the removal of a surface coating.

摘要： A grain-oriented electromagnetic steel sheet has an ultra low watt loss and heat resistant subdivided magnetic domains. The electromagnetic steel sheet has spaced apart regions of plastic strain and an insulating coating disposed thereon. Intruders are thermally intruded into the spaced apart regions of plastic strain causing the subdivided magnetic domains to be heat resistant and maintaining the subdivided magnetic domains after stress relief annealing. Preferred intruders include Sb and Sb containing materials.
