COLD ROLLED STEEL SHEET HAVING EXCELLENT ENAMELABILITY

摘要

Steel sheets having an excellent enamelability are produced by adjusting the carbon, silicon, manganese, aluminum, oxygen and boron contents in a molten steel to be not more then 0.020% of carbon, not more than 0.0% of silicon, not more than 0.50% of manganese, not more then 0.010% of aluminum, not more than 0.050% of oxygen, boron within a range of 0.003-0.020% being in such an amount B(%)x0(%) of more than 1x10-5 and the remainder being inevitable impurities and iron, and hot rolling the resulting steel, cold rolling the steel and subjecting to a recrystallization annealing in a conventional manner.
