Chingwe chachitsulo chosapanga dzimbiri cha 420J1 420J2
Kufotokozera Kwachidule:
Zingwe zachitsulo zosapanga dzimbiri za 420J1 ndi 420J2 ndi mitundu iwiri yodziwika bwino ya zipangizo zosapanga dzimbiri zomwe zili m'gulu la zitsulo zosapanga dzimbiri za martensitic. Zili ndi kusiyana pang'ono pa kapangidwe ka mankhwala ndi makhalidwe ake. Nayi chidule cha chilichonse:
1. Chitsulo chosapanga dzimbiri cha 420J1: 420J1 ndi chitsulo chosapanga dzimbiri chopanda kaboni wambiri chomwe chili ndi kuuma kwakukulu komanso mphamvu zambiri. Mankhwala ake nthawi zambiri amakhala ndi kaboni pafupifupi 0.16-0.25%, pafupifupi 1% chromium, ndi molybdenum yochepa. 420J1 imapereka kukana dzimbiri bwino, kudula bwino, komanso mphamvu zopera. Nthawi zambiri imagwiritsidwa ntchito popanga mipeni, zida zopangira opaleshoni, zida zamakanika, ndi zina zomwe sizingawonongeke.
2. Chitsulo chosapanga dzimbiri cha 420J2: 420J2 ndi chitsulo chosapanga dzimbiri chapakati chokhala ndi kuuma kwakukulu komanso kusawonongeka. Mankhwala ake nthawi zambiri amakhala ndi kaboni pafupifupi 0.26-0.35% ndi pafupifupi 1% ya chromium. 420J2 ili ndi kaboni wambiri poyerekeza ndi 420J1, zomwe zimapangitsa kuti ikhale yolimba komanso yodula bwino. Nthawi zambiri imagwiritsidwa ntchito popanga mipeni, masamba, zida zopangira opaleshoni, masiponji, ndi zida zina zamakanika.
