For example, according to GOST 2685-75, the permissible iron content varies depending on the casting method. For sand and shell molds, the iron limit is stricter, while for chill casting it is ≤ 1.40%, and for pressure die casting it is ≤ 1.50%. The standard mandates that the composition must remain within these tightly controlled ranges to guarantee the material's properties.
Note: While many resources for this standard are in Russian, its application is global in international engineering projects involving Russian-designed machinery.
