The is an indispensable resource for anyone reverse-engineering Soviet/Russian machinery or sourcing magnesium castings from Eastern Europe. It provides the hard data required to ensure material compliance.

Despite being superseded, GOST 2685-75 remains a valuable historical document and is frequently referenced in technical literature, older repair manuals, and in the specifications for legacy industrial equipment. For current manufacturing projects, however, it is crucial to refer to the latest version (GOST 1583-93 or its modern equivalent) to ensure compliance.

: Standardized codes (e.g., T1, T4, T6) that specify the tempering and aging processes required to achieve specific mechanical properties.

If you are using this for critical applications (aerospace, automotive, defense), do not rely on a low-resolution scan found on a forum. Ensure you have a high-quality copy or access to an official standards database to verify the chemical limits are accurate.
