30CRMOV9 / 1.7707 Aloyi zitsulo

30CrMoV9 ndi chitsulo chomwe nthawi zambiri chimapangidwira kupanga zida zozimitsidwa komanso zotenthedwa, zomwe nthawi zambiri zimapangidwa ndi makina kenako ndi nitrided. Aloyi 30CrMoV9 nthawi zambiri amapangidwa ndi EAF /VD /LF kutsatiridwa ndi electroslag kuyenga (ESR) ngati n'koyenera kwa cholinga chapadera. Mipiringidzo ndi, ngati kuli kotheka, forgings amayesedwa akupanga kutengera mlingo wosiyana malinga ndi ogula’ zofunika. Ma bar nthawi zambiri amaperekedwa mowala ngati ali olumikizidwa, kapena owala kwambiri makamaka.
