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.
The GOST 2685-75 standard quickly gained international recognition and adoption. Its influence extended beyond the Soviet Union, with many countries incorporating its principles into their own national standards. The standard's focus on interchangeability, precision, and efficiency resonated with industries worldwide, from aerospace and automotive to machinery and manufacturing. gost 2685-75 pdf
