 After permanent annealing between 500-900 C, these steels show a notch toughness of 4 to
 EMI1.4
 The limit of the scaling resistance has been increased by about 1800 compared to the pure chrome-manganese steels, whose valuable properties are retained in the steels according to the invention.



     Steels whose Si + Al content deviates from the rule by + 0-5% are also covered by the invention.
