18 Tausaga Falegaosi Uamea Uila Seamless - 17-4PH 630 1.4542 H900 mama mama e tusa ai ma ata - Huaxin Fa'amatalaga:
1) AMS 5643 (17/4 PH) o se American aerospace grade uʻamea uʻamea ma 4% apamemea e mafai ona faamaaa.
e ala i le maualalo o le vevela o timuga faʻamaʻaʻaina togafitiga vevela e maua ai mea faʻainisinia sili ona lelei ile maualuga
tulaga malosi.
2) tulaga:
E mafai ona tu'uina atu i se tulaga fa'afefeteina (Tulaga A), po'o le fa'afefeteina e fa'apea:-
Tulaga H900 (900°F) Tulaga H925 (925°F) Tulaga H1025 (1025°F) Tulaga H1075 (1075°F) Tulaga
H1100 (1100°F) Tulaga H1150 (1150°F)
AMS 5643 (17/4 PH) mea e le tatau ona faʻaogaina i le tulaga faʻapipiʻi. O lenei vasega o u'amea uamea ei ai se masani
mamafa ole 7.75kg/dm3 ma e magnetizable.

5. AMS 5643 Tete'e a'e:
AMS 5643 (17/4 PH) e sili atu nai lo togi sa'o chrome e pei ole 410 ma fa'alatalata atu ile fa'a'a'a'a ole nickel.
togi chrome. I le tele o fa'asalalauga fa'aleaga, e tutusa ma le vasega 302. E a'afia le tete'e o le a'a i le mae'a i luga ma
togafitiga vevela matua. AMS 5643 (17/4 PH) uelo lelei ma e mafai ona ueloina i faiga faapisinisi uma. mua'i fa'avevela ma
e le mana'omia ni faiga fa'amulimuli o fa'ailoga u'amea fa'ama'a fa'amalosi.
6. AMS 5643 Talosaga :
Mo talosaga e manaʻomia ai le malosi maualuga ma le lelei o le corrosion resistance, faʻapea foʻi ma le maualuga o le vaivai malosi, lelei le ofuina o lavalava
ma fa'amamafa tete'e a'a. E fetaui lelei mo vaega lavelave e manaʻomia ai masini ma uʻamea, ma manaʻomia le saʻolotoga o le faʻaleagaina.
Fa'aaogaina i le va'alele, puipuiga o suau'u i fafo ma fale kesi. E faʻaaogaina mo vaega faʻainisinia e pei o vaega taʻiala, afi afi, valve stems,
mea fa'aoga, ma isi.

Taiala Fa'atatau Oloa:
Fa'amanino "Fa'atau muamua, Tulaga muamua" i le mafaufau, matou te galulue vavalalata ma a matou tagata fa'atau ma tu'uina atu ia i latou auaunaga lelei ma fa'apolofesa mo le 18 Tausaga Fale Fa'ameamea Fa'ameamea Seamless - 17-4PH 630 1.4542 H900 mama mama e tusa ai ma ata - Huaxin, Le oloa o le a sapalai i le lalolagi atoa, e pei o: Kenya, Bangladesh, Niu Sila, Matou te talitonu o sootaga lelei pisinisi o le a taʻitaʻia ai le manuia ma le faʻaleleia atili mo itu uma e lua. Ua matou fa'atūina so'otaga felagolagoma'i umi ma manuia ma le tele o tagata fa'atau e ala i lo latou fa'atuatuaina oa matou auaunaga fa'apitoa ma le fa'amaoni i le faia o pisinisi. Matou te fiafia foi i se igoa maualuga e ala i la matou faatinoga lelei. O le a sili atu le faatinoga o le a faamoemoeina e avea ma a tatou mataupu faavae o le faamaoni. O le tuuto ma le Tumau o le a tumau e pei ona masani ai.
