Xariijimaha birta aan daxalka lahayn ee 420J1 420J2
Sharaxaad Gaaban:
Xariijimaha birta aan daxalka lahayn ee 420J1 iyo 420J2 waa laba nooc oo agab bir aan daxalka lahayn ah oo caadi ah oo ka tirsan taxanaha birta aan daxalka lahayn ee martensitic. Waxay leeyihiin farqi yar oo ku saabsan halabuurka kiimikada iyo astaamaha. Waa kan dulmar kooban oo mid walba ah:
1. Xariijimaha birta aan lahayn ee 420J1: 420J1 waa bir aan lahayn kaarboon yar oo leh adkeysi iyo xoog sare. Halabuurka kiimikada badanaa wuxuu ka kooban yahay qiyaastii 0.16-0.25% kaarboon, qiyaastii 1% chromium, iyo xaddi yar oo molybdenum ah. 420J1 wuxuu bixiyaa iska caabin wanaagsan oo daxalka ah, waxqabadka jarista, iyo sifooyinka shiididda. Waxaa badanaa loo isticmaalaa sameynta mindiyaha, qalabka qalliinka, qaybaha farsamada, iyo codsiyada qaarkood ee u adkaysta xirashada.
2. Xariijimaha birta aan lahayn ee 420J2: 420J2 waa bir aan lahayn wax kaarboon dhexdhexaad ah oo leh adkeysi sare iyo iska caabin xirasho. Halabuurka kiimikada badanaa wuxuu ka kooban yahay qiyaastii 0.26-0.35% kaarboon iyo qiyaastii 1% chromium. 420J2 wuxuu leeyahay kaarboon ka sarreeya marka loo eego 420J1, taasoo keenta adkaansho iyo waxqabad goyn oo kordha. Waxaa si joogto ah loogu isticmaalaa soo saarista mindiyaha, daabyada, qalabka qalliinka, guluubyada, iyo qaybo farsamo.
