Hastelloy C-4
Fa'amatalaga Puupuu:
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Va'aiga ma Talosaga Va'aiga lautele:
O le u'amea o se austenitic low-carbon nickel-molybdenum-chromium alloy. O le eseesega tele i le va o le Nicrofer 6616 hMo ma isi mea faʻapipiʻi tutusa vailaʻau faʻatupuina muamua o le maualalo carbon, silicon, uʻamea ma tungsten. O lenei vailaʻau vailaʻau e maua ai le mautu lelei i le 650-1040 ° C ma faʻaleleia atili le teteʻe atu i le faʻaleagaina o le vaeluagalemu, aloese mai le faʻafefe o le laina pito i luga ma faʻafefe HAZ i lalo o tulaga talafeagai o gaosiga. Alloy fa'aaogaina i faiga fa'a'ele'ele'ele'ele kasa, fa'ato'aga fa'ato'aga fa'ato'aga, fa'ato'aga acetic acid ma vaila'au fa'ato'aga, gaosiga o le titanium dioxide (auto'a chloride), fa'apipi'i eletise.

Hastelloy C-4 fa'atinoga fa'atinoga ma mana'oga:
1, I le faagasologa o le vevela e le mafai ona faʻafesoʻotaʻi ma le sulfur, phosphorus, taʻitaʻi ma isi uʻamea maualalo maualalo, pe o le a faʻafefeteina le uʻamea, e tatau ona gauai atu e aveese e pei o le makaina o le vali, vali faʻailoga vevela, penivali lanu, lubricants, suauu. ma isi palapala. O le maualalo o le sulfur i totonu o le suauu e sili atu ona lelei, o le sulfur i totonu o le kasa masani e tatau ona itiiti ifo i le 0.1%, o le sulfur i totonu o le suauu mamafa e tatau ona itiiti ifo i le 0.5%. O le faʻavevelaina o le ogaumu eletise o se filifiliga sili atu, aua o le ogaumu eletise e mafai ona faʻatonutonu saʻo le vevela ma mama le kesi ogaumu. Afai e lava mama le ogaumu kesi kesi, e mafai ona e filifili.
2, u'amea vevela faagasologa vevela vaega o le 1080 ℃ ~ 900 ℃, cooling auala mo vai cooling po o isi cooling vave. Ina ia faʻamautinoa le sili atu ona lelei le faʻafefeteina, e tatau ona faia togafitiga vevela pe a maeʻa togafitiga vevela fofo.
