Folasaga puupuu:

u'amea u'amea, e ta'ua fo'i o le u'amea lafo, u'amea nodular, u'amea graphite spherical, u'amea spherical graphite ma u'amea SG, o se ituaiga o u'amea-mau'oa graphite na maua i le 1943 e Keith Millis.E ui o le tele o ituaiga o u'amea lafo e vaivai i le vevesi ma malepelepe, u'amea ductile e sili atu le aafiaga ma le vaivai tetee, ona o lona nodular graphite inclusions.O le u'amea pa'u'u e le o se mea e tasi ae o se vaega o se vaega o mea e mafai ona gaosia ma le tele o mea totino e ala i le pulea o latou microstructure.O le uiga masani o lenei vaega o meafaitino o le foliga o le graphite.I u'amea ductile, graphite i foliga o nodules nai lo flakes pei o le u'amea efuefu.A'o pa'u ma'ai graphite e fa'atupuina ai le fa'amafa'aga i totonu o le u'amea, o nodul lapotopoto e taofia ai le fa'atupuina o ta'eta'ei, ma fa'apena ai le fa'aleleia atili o le ga'o lea e fa'aigoaina ai le fa'aigoa.

Austempered ductile iron (ADI; ie, austenite tempered[7]) na maua i le 1950s ae na fa'atauva'a ma maua manuia i nai tausaga mulimuli ane.I le ADI, o le fausaga uʻamea o loʻo faʻaogaina e ala i se faiga faʻafefe vevela.

Tulaga

Fa'asagaga fa'atele (%) mo u'amea ferritic ductile [8]

O isi u'amea ductile e masani ona i ai se vaega itiiti o le sulfur.

Carbon, 3.2–3.60%

Siliko, 2.2–2.8%

Manganese, 0.1–0.2%

Manesium, 0.03–0.04%

Phosphorus, 0.005–0.04%

Sulfur, 0.005–0.02%

Kopa, <0.40%

Uamea, paleni

O elemene e pei o le kopa poʻo le apa e mafai ona faʻaopoopoina e faʻateleina ai le malosi ma maua ai le malosi aʻo faʻaititia i le taimi e tasi.E mafai ona ausia le faʻaleleia atili o le faʻafefeteina e ala i le suia o le 15-30% o le uʻamea i totonu o le uʻamea ma le tele o nikeli, kopa, poʻo le chromium.

Silicon e avea o se elemene fausia graphite e mafai ona sui vaega i le alumini e maua ai le puipuiga oxidation sili atu.[9]

HONGDA u'amea u'amea:

I le amataga o le 2021, na fausia ai e HONGDA se falegaosimea fou e faʻafeiloaʻi ai meafaigaluega ma laina gaosiga mo le faʻaaogaina o le uʻamea.
1. Mea: QT450 #-10 ma Spheroidization fua faatatau i luga o le tulaga III e maua ai se tulaga lelei o castings e lagolago lau talosaga.
2. Laina gaosiga otometi e oʻo atu i le maualuga maualuga ma le tele o le gaosiga gafatia, 550T / Masina, e toe faʻafoʻi ai lou manaʻoga faanatinati.
3.Applications: u'amea ductile u'amea castings mo le kola fa'a, paie puipui ma e pei o vaega castings i totonu o le 70KGS.undercarriage vaega ala taavale rim excavator sprocket
