摘要： The adhesiveness of a glass film and watt loss of a grain-oriented electrical steel sheet is improved by partially protruding the glass film into the steel sheet part thereof. To attain the partial protrusion, the steel sheet is subjected, prior or subsequent to decarburization annealing, to a treatment of the surface thereof to form unevenness, by a mechanical device, e.g., brush rolling, buff polishing, marking-off, sand papering, and grinding.

摘要： A compound steel material of high corrosion resistance is manufactured by alloying a carbon steel carrier material having a carbon content of at most 0.20C and of at least 0.04C with a carbide and nitride forming substance, compounding the alloyed carrier material with a ferritic chromium steel material of normal carbon content, followed by hot-rolling the compound steel material to a hot rolled strip or sheet which is then annealed at a temperature and for a time period sufficient for the carbon content of the ferritic chromium steel coating layer to be reduced to between 0.001 and 0.003% so as to increase the corrosion resistance of the chromium steel material to that of a superferritic material. After annealing, the sheet may be etched and surface-finished or cold-rolled, recrystallization annealed and thereafter surface-finished, such as temper-rolled. The ferritic chromium steel material has at most 0.1% of carbon prior to annealing. The carbide and nitride forming substance may be titanium whose content in the alloyed carrier material is preferably between 0.50% and 2.00%. The thickness of the ferritic chromium steel coating layer is between 50 and 500 .mu.m, the annealing temperature between 650.degree. and 900.degree. C., and the annealing time period between 8 and 72 hours.

摘要： A compound steel material of high corrosion resistance is manufactured by alloying a carrier material of deep-drawing grade with a carbide and nitride forming substance, compounding the alloyed carrier material with a chromium steel material of normal carbon content, followed by annealing the compound steel material at a temperature and for a time period sufficient for the carbon content of the ferritic chromium steel coating layer to be reduced to between 0.001 and 0.003% so as to increase the corrosion resistace of the chromium steel material to that of a superferritic material. Prior to annealing, the compound steel material may be rolled to a fine sheet. The carrier material used in the method of the invention is a deep-drawing steel of at most 0.12% of carbon, while the ferritic chromium steel material has at most 0.1% of carbon prior to the annealing. The carbide and nitride forming substance may be titanium whose content in the alloyed carrier material is preferably between 0.5 and 2%. The thickness of the ferritic chromium steel coating layer is between 50 and 500 .mu.m, the annealing temperature between 650 and 900.degree. C., and the annealing time period between 8 and 72 hours.
