Forgings. Forgings Process
Forgings are made by free forging on forging presses and hammers followed by heat treatment and mechanical processing.
The forgings are delivered certified as compliant with GOST 8479-70, GOST 25054-81, Industrial Standard 108.109.01-92, Industrial Standard 108.030.113-87, Standard by the Central Design Bureau of Armature Engineering, Industrial Standard 5Р.9125-84 and other standards and terms.
We may deliver forgings accompanied by Quality Plans accepted by JSC All-Russian Production Association Zarubezhatomenergostroy (JSC “VPO “ZAES”) and Russian River Register as well as accepted by the Defense Ministry using destructive and non-destructive test methods in certified laboratories (ultrasonic testing, mechanical tests, inter-crystalline corrosion resistance tests, macrostructure and microstructure tests), with standardized value of the grain size, ferritic phase and non-metallic inclusions.
