STANDARDS & EQUIVALENT GRADES
GOST 08кп

HEAT TREATMENT
Typically normalized (880–920 °C, air cool) or carburized (900–930 °C) for case-hardening grades, then quenched and tempered at 150–200 °C.

PROCESSING PRECAUTIONS
Weldable with standard procedures; preheat may be needed for thick sections or higher-carbon/ alloy grades. Protect from decarburization during heating (controlled atmosphere or protective coating).
