In 2015, the Russian Federation began harmonizing its GOST standards with ISO. is currently under review for replacement by GOST ISO 1224-1 (Instrument bearings – single-row angular contact ball bearings). However, due to the massive installed base of legacy machinery, the 2025 to 2030 transition period means the PDF will remain a valid reference for decades.

: Outlines performance expectations for different techniques: Sand and Shell Molds : Often used for large, complex parts. Investment Casting : Used for high-precision models. gost 2685-75 pdf
A: The standard recognized that different casting technologies—such as sand casting or pressure die casting—impose different requirements on the alloy's fluidity and tendency to form brittle intermetallic phases. Therefore, strict but method-specific limits were set for iron content.
The standard defines which alloying elements are allowed, their percentages, and the mechanical properties (tensile strength, elongation) that finished castings must meet. 2. Scope of the Standard (Grades Covered) In 2015, the Russian Federation began harmonizing its
