◦ Muyezo wogwiritsira ntchito: GB/T1222-2007.
◦ Kuchuluka: 7.85 g/cm3.
• Kapangidwe ka mankhwala
◦ Mpweya (C): 0.62% ~ 0.70%, zomwe zimapangitsa kuti zinthu zikhale zolimba komanso zokhazikika.
◦ Manganese (Mn): 0.90% ~ 1.20%, zomwe zimapangitsa kuti zinthu zikhale zolimba komanso kuti zikhale zolimba.
◦ Silikoni (Si): 0.17% ~ 0.37%, zomwe zimapangitsa kuti ntchito yokonza zinthu iyende bwino komanso kuti mbewu zisamayende bwino.
◦ Phosphorus (P): ≤0.035%, sulfure (S) ≤0.035%, kulamulira mosamala kuchuluka kwa zodetsa.
◦ Chromium (Cr): ≤0.25%, nickel (Ni) ≤0.30%, mkuwa (Cu) ≤0.25%, zinthu zosakaniza, zomwe zimathandiza kukonza magwiridwe antchito.
• Kapangidwe ka makina
◦ Mphamvu yayikulu: Mphamvu yokoka σb ndi 825MPa~925MPa, ndipo deta ina ili pamwamba pa 980MPa. Ili ndi mphamvu yabwino kwambiri yoperekera mphamvu ndipo ndi yoyenera pamavuto akulu.
◦ Kutanuka kwabwino: Ili ndi malire okwera otanuka, imatha kupirira kusintha kwakukulu kwa elastic popanda kusintha kosatha, ndipo imatha kusunga ndikutulutsa mphamvu molondola.
◦ Kulimba kwambiri: Pambuyo potenthedwa, imatha kufika HRC50 kapena kupitirira apo, yokhala ndi kukana kwakukulu kwa kuvala, yoyenera kuvala.
◦ Kulimba kwabwino: Ikakhudzidwa ndi zinthu zolemera, imatha kuyamwa mphamvu zinazake popanda kusweka, zomwe zimapangitsa kuti ikhale yodalirika komanso yogwira ntchito bwino m'mikhalidwe yovuta.
• Makhalidwe
◦ Kulimba kwambiri: Manganese imalimbitsa kwambiri, yoyenera kupanga masiponji ndi zigawo zazikulu zokhala ndi mainchesi opitilira 20mm.
◦ Kuchepa kwa kagayidwe ka mafuta pamwamba: Ubwino wa pamwamba umakhala wokhazikika panthawi yotenthetsera, zomwe zimachepetsa chiopsezo cholephera msanga.
◦ Kutentha kwambiri komanso kufooka kwa kutentha: Kutentha kozimitsa kuyenera kulamulidwa mosamala, ndipo kutentha kozimitsa kuyenera kupewedwa panthawi yozimitsa.
◦ Kugwira ntchito bwino pokonza: kumatha kupangidwa ndi kuwotcherera, koyenera kupanga zinthu zooneka ngati zovuta, koma kuzizira kwa pulasitiki kumakhala kochepa.
• Zofunikira pa chithandizo cha kutentha
◦ Kuzimitsa: Kutentha kozimitsa 830℃±20℃, kuziziritsa mafuta.
◦ Kutenthetsa: Kutentha kwa kutentha 540℃±50℃, ±30℃ pakakhala zosowa zapadera.
◦ Kubwezeretsa kutentha: Kutentha 810±10℃, kuziziritsa mpweya.
• Madera ogwiritsira ntchito
◦ Kupanga masika: monga masika a masamba a magalimoto, masika a shock absorber, masika a valve, ma clutch backs, ndi zina zotero.
◦ Zigawo zamakina: zingagwiritsidwe ntchito popanga zida zonyamula katundu wambiri komanso zokokera kwambiri monga magiya, mabearing, ndi ma pistoni.
◦ Zida zodulira ndi zopondera: pogwiritsa ntchito kuuma kwake kwakukulu komanso kukana kuwonongeka, ingagwiritsidwe ntchito popanga zida zodulira, zopondera, ndi zina zotero.
◦ Nyumba ndi milatho: zingagwiritsidwe ntchito popanga zinthu zomwe zimawonjezera mphamvu ya mabearing a nyumba, monga mabearing a mlatho, zothandizira nyumba, ndi zina zotero.
