Composition and properties
In Russia and CIS CR-mo structural steel 30KHM produced according to technical requirements GOST 4543. It has a chemical composition:
|The content in steel, %||0,26 0,34…||0,17…0,37||0,40…0,70||0,80 1,10…||0,15…0,25|
The current standard allows in steel metallurgical impurities — sulfur and phosphorus, but their percentage should not exceed the value of 0.025…0,030% for each of the elements.
The closest foreign analogues of this steel are steel grades 25CrMo4 1.7218 and. Their chemical composition is the following:
|The content in steel, %||0,22 0,29…||To 0.40||0,60…0,90||0,90 1,20…||0,15 0,30…|
