    420J1 ndi 420J2 zitsulo zosapanga dzimbiri ndi mitundu iwiri yodziwika bwino yazitsulo zosapanga dzimbiri zomwe zili m'gulu la zitsulo zosapanga dzimbiri za martensitic. Iwo ali ndi kusiyana kwa mankhwala zikuchokera ndi makhalidwe. Nayi chidule cha chilichonse:

    1. 420J1 chitsulo chosapanga dzimbiri: 420J1 ndi chitsulo chosapanga dzimbiri chochepa cha carbon chokhala ndi kuuma kwakukulu ndi mphamvu. Kapangidwe kake kake kamakhala kozungulira 0.16-0.25% kaboni, pafupifupi 1% chromium, ndi molybdenum pang'ono. 420J1 imapereka kukana kwa dzimbiri kwabwino, kudula, ndi kugaya. Amagwiritsidwa ntchito kwambiri popanga mipeni, zida zopangira opaleshoni, zida zamakina, ndi zina zomwe sizitha kuvala.

    2. 420J2 chitsulo chosapanga dzimbiri: 420J2 ndi chitsulo chosapanga dzimbiri cha carbon cholimba kwambiri komanso kukana kuvala. Mankhwala ake nthawi zambiri amakhala ndi 0.26-0.35% ya carbon ndi pafupifupi 1% chromium. 420J2 ili ndi mpweya wochuluka poyerekeza ndi 420J1, zomwe zimapangitsa kuti zikhale zovuta komanso zodula. Nthawi zambiri amagwiritsidwa ntchito popanga mipeni, zipsera, zida zopangira opaleshoni, akasupe, ndi zida zina zamakina.

    3. Zida zomwe timapereka ndizotsimikizika kotheratu, kuyambira pa chiphaso choyezera zinthu mpaka pachiwonetsero chomaliza. (Malipoti awonetsa pakufunika)
    4. e chitsimikizo kupereka yankho mkati 24hours(nthawi zambiri mu ola lomwelo)
    5. Mutha kupeza njira zina zogulitsira, zoperekera mphero ndikuchepetsa nthawi yopanga.
    6. Ndife odzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zomwe mukufuna mutapenda zonse zomwe mungasankhe, sitidzakusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino ndi makasitomala.
