① It is allowed to replace tungsten partially with molybdenum in tungsten steels: one fraction of the total mass of tungsten is equivalent to one fraction of the total mass of molybdenum.
The quantity of the replaced tungsten shall be no more than 0.1 % in steels with the fraction of the total mass of tungsten not exceeding 1.5 %. It shall be no more than 0.2 % in steels with the fraction of the total mass of tungsten not exceeding 2 %.
The sum fraction of the total mass of tungsten and molybdenum shall not exceed the specified fraction of the total mass of tungsten.
