Abstract: A steel composed of from 0.004 to 0.05% of carbon, from 0.10 to 4.0% of silicon, not in excess of 0.45% of manganese, not in excess of 0.60% of aluminum, from 0.030 to 0.250% of phosphorus, from 0.02 to 0.2% of zirconium, and the remainder iron with impurities inherent to the manufacturing process. The invention also includes the method of making a steel band which includes the steps of intermixing in liquid condition and in a vacuum from 0.004 to 0.05% of carbon, 0.10 to 4.0% of silicon, not in excess of 0.45% of manganese, not more than 0.60% aluminum, from 0.030 to 0.250% of phosphorus, from 0.02 to 0.2% of zirconium, and the remainder iron with impurities inherent to the manufacturing process, warm rolling the thus obtained composition into a band, pickling said band and cold rolling it, and subsequently passing the thus treated band through a continuous heating furnace while annealing said last mentioned band at a temperature of from 750.degree. to 1250.degree. C for a time period of from 1 to 7 minutes.
