420J1 420J2 Mzere wachitsulo wosapanga dzimbiri
Kufotokozera kwaifupi:
420J1 ndi 420j2 zingwe zosapanga dzimbiri ndi mitundu iwiri ya zinthu zachitsulo zomwe zimakhala za kapangidwe ka chitsulo chosapanga dzimbiri. Amakhala ndi zosiyana pakupanga mankhwala ndi mawonekedwe. Nayi chidule chachidule chilichonse:
1. Mankhwala ake amaphatikizapo pafupifupi 0.16-0.25% kaboni, pafupifupi 1% chromium, ndi zochepa za Molybdenum. 420J1 Amapereka kukana bwino kukana, kudula magwiridwe, ndi zopera. Zimagwiritsidwa ntchito popanga mipeni, zida zopangira zopangira opaleshoni, makina, komanso kugwiritsa ntchito njira zina zosagwirizana.
2. Mankhwala ake nthawi zambiri amakhala ndi 0,26-0.35% kaboni ndi pafupifupi 1% chromium. 420J2 ili ndi zokhala ndi mpweya wapamwamba poyerekeza ndi 420JJ1, zomwe zimapangitsa kuwuka ndi kutsika. Nthawi zambiri zimagwiritsidwa ntchito popanga mipeni, masamba, zida zopangira opaleshoni, akasupe, ndi makina ena.
