② It is allowed to replace molybdenum partially with tungsten in molybdenum steels: one fraction of the total mass of molybdenum is equivalent to two fractions of the total mass of tungsten.
The quantity of the replaced molybdenum shall be no more than 0.1 % in steels with the fraction of the total mass of molybdenum not exceeding 1.2 % inclusive. It shall be no more than 0.2 % in steels with the fraction of the total mass of milybdenum exceeding 1.2 %.
The sum fraction of the total mass of tungsten, counted to molybdenum, and molybdenum itself shall not exceed the specified fraction of the total mass of molybdenum.
