420J1 420J2 xariijimo bir ah
Sharaxaad Gaaban:
420J1 iyo 420J2 strips ahama waa laba nooc oo caadi ah oo ahama birta ah oo ka tirsan taxanaha birta martensitic. Waxay leeyihiin xoogaa kala duwanaansho ah oo ka kooban kiimikada iyo sifooyinka. Waa kan dulmar kooban mid walba:
1. 420J1 strip bir ahama: 420J1 waa bir aan kaarboon-yar oo hooseeya oo adag iyo xoog badan. Halabuurka kiimikada sida caadiga ah waxaa ka mid ah qiyaastii 0.16-0.25% kaarboon, qiyaastii 1% chromium, iyo xaddi yar oo molybdenum ah. 420J1 waxay bixisaa iska caabin daxalka wanaagsan, goynta waxqabadka, iyo guryaha shiidi. Waxaa caadi ahaan loo isticmaalaa samaynta mindiyaha, qalabka qalliinka, qaybaha makaanikada, iyo qaar ka mid ah codsiyada xidhashada u adkaysta.
2. 420J2 strip bir ahama: 420J2 waa bir dhexdhexaad ah-carbon ahama leh engegnaanta sare iyo xidho iska caabin ah. Halabuurka kiimikaadku wuxuu inta badan ka kooban yahay 0.26-0.35% kaarboon iyo ilaa 1% chromium. 420J2 waxay leedahay kaarboon sare marka loo eego 420J1, taasoo keentay kororka qallafsanaanta iyo goynta waxqabadka. Waxaa inta badan loo isticmaalaa wax soo saarka mindiyaha, daabadaha, qalabka qalliinka, ilo, iyo qaybo ka mid ah farsamada.
