kufunikira kwa magwiridwe antchito
(1) Mphamvu yayikulu: nthawi zambiri, mphamvu zake zokolola zimaposa 300MPa.
(2) Kulimba kwambiri: kutalika kofunikira ndi 15% ~ 20%, ndipo kulimba kwamphamvu pa kutentha kwachipinda kumakhala kwakukulu kuposa 600kJ/m~800kJ/m. Pazigawo zazikulu zowotcherera, kulimba kwapang'onopang'ono kumafunikanso.
(3) Good kuwotcherera ntchito ndi ozizira kupanga ntchito.
(4) Kutentha kochepa kozizira kozizira.
(5) Kukana bwino kwa dzimbiri.
3. Makhalidwe apangidwe a chitoliro cha galvanized
(1) Mpweya wochepa: chifukwa cha zofunika kwambiri za kulimba, weldability ndi kuzizira kupanga ntchito, zomwe zili ndi mpweya sizidzapitirira 0.20%.
(2) Manganese based alloy element amawonjezedwa.
(3) Kuphatikiza kwa niobium, titaniyamu kapena vanadium: niobium pang'ono, titaniyamu kapena vanadium imapanga carbide yabwino kapena carbonitride muchitsulo, yomwe imathandizira kupeza mbewu zabwino za ferrite ndikuwongolera mphamvu ndi kulimba kwachitsulo. Kuonjezera apo, kuwonjezera pang'ono mkuwa (≤ 0.4%) ndi phosphorous (pafupifupi 0.1%) kungapangitse kukana kwa dzimbiri. Kuwonjezera pang'ono zinthu zapadziko lapansi zosowa kumatha kuchotsa sulfure ndi gasi, kuyeretsa chitsulo, ndikuwongolera kulimba ndi kukonza magwiridwe antchito.
