Alloy steel stamps 18KH2N4MA produced in Russia and CIS according to the requirements of GOST 4543. It has higher percentage of molybdenum and Nickel, which follows from the table:
|The percentage||0,14…0,20||0.17 0,37…||Of 0.25 to 0.55||1,55 1,65…||4,0…4,4||Of 0.30…0,40|
In the steel allowed the metallurgical impurities — sulfur and phosphorus, the percentage of which is limited to 0.025…0,030%.
European and North American counterparts have become 18KH2N4MA are brand Х19NiCrMo4 and 1.6657. They are produced accordingly to the technical requirements of DIN 17210 (for Europe) and SAE-AISI 9310 (US). The composition of these steels is somewhat different from domestic ones. For example, steel 1.6657 has the following chemical composition:
|The percentage||0,11 0,17…||To 0.40||0,30…0,60||0,80 1,15…||3,0…3,5||0,10…0,25|
The steel is lowered in the presence of sulfur and phosphorus in an amount of not more than 0,035%.
