Fuafuaga Fa'atusatusa aupito lata mai o Vasega Silasila
u'amea u'amea e masani ona fa'aaogaina i le lalolagi gaosi oloa, ae ona o tulaga eseese ma le fa'aigoaina o metotia o le u'amea u'amea i atunu'u eseese ma itulagi, e masani ona i ai ni fa'alavelave i le malamalama ma feso'ota'iga. Ina ia fesoasoani i pisinisi ma tagata faʻatau e sili atu ona iloa ma filifili mea talafeagai, ua tuʻufaʻatasia e JIEHUANG se laulau faʻatusatusaga faʻavaomalo faʻavaomalo o togi uʻamea. O lenei laulau e faʻatusatusa ai tulaga faʻavaomalo faʻavaomalo (e pei o le GB a Saina, tulaga ASTM a le Iunaite Setete, tulaga Europa EN ma Iapani JIS) mo le vave faʻasino pe a filifilia ma faʻatau mea uʻamea. O lenei mea e le gata e mafai ona faʻaleleia atili le lelei o le faʻatauga o tuaoi, ae fesoasoani foi e faʻamautinoa le saʻo ma le faʻamaoni o mea filifilia.

RFQ:
1. O le a le corrosion teteʻe o uʻamea stainless eseese?
304 o se u'amea u'amea fa'amoemoe lautele lea e fa'aaogaina lautele e fai ai meafaigaluega ma vaega e mana'omia ai le fa'atinoga lelei atoatoa (tete'e ma le fa'atulagaina). 301 u'amea u'amea o lo'o fa'aalia manino le fa'ama'a'aina o galuega pe a fa'aleagaina ma fa'aaogaina i taimi eseese e mana'omia ai le malosi maualuga.
302 u'amea u'amea o le mea moni o se fesuiaiga o 304 u'amea u'amea ma se maualuga carbon anotusi, lea e mafai ona faia e maua ai le malosi maualuga e ala i taʻavale malulu.
302B o se u'amea u'amea fa'atasi ai ma le silicon content ma e maualuga atu le tete'e i le vevela vevela. O le 303 ma le 303Se o u'amea e leai se totogi e maua ai le sulfur ma le seleni, lea e fa'aaogaina i taimi e mana'omia ai le tipiina fua ma le maualuga maualuga. 303Se u'amea u'amea e fa'aaogaina foi e fai ai vaega e mana'omia ai le vevela vevela aua i lalo o ia tulaga, o lenei uamea e leai se mea e mafai ona galue lelei.
304L o se fesuiaiga o le 304 uʻamea uʻamea ma le maualalo carbon anotusi ma faʻaaogaina i taimi e manaʻomia ai le uelo. O le kaponi pito i lalo e fa'aitiitia ai le fa'afefe o carbide i totonu o le sone ua afaina i le vevela e lata ane i le uelo, ma o le timu o carbide e mafai ona mafua ai le pala (weld erosion) o u'amea u'amea i nisi siosiomaga.
304N o se u'amea u'amea e maua ai le nitrogen, ma fa'aopoopo le nitrogen e fa'ateleina ai le malosi o le sila.
305 ma le 384 u'amea u'amea o lo'o i ai mea e sili atu le nickel ma e maualalo le fa'ama'a'aina o galuega, ma fa'atatau mo taimi eseese ma maualuga mana'oga mo le malulu.
308 u'amea uamea e fa'aaogaina e fai ai u'amea.
309, 310, 314 ma le 330 u'amea u'amea uma e maualuga atu le nickel ma le chromium i totonu ina ia faʻaleleia ai le faʻamaʻi faʻamaʻi ma le malosi fetolofi o le sila i le maualuga o le vevela. 30S5 ma le 310S o eseesega o 309 ma 310 stainless steels, na o le pau lava le eseesega o loʻo i ai le maualalo o le carbon content ina ia faʻaitiitia ai le faʻafefe o carbide i tafatafa o le uelo. 330 u'amea u'amea e faapitoa le tetee maualuga i carburization ma te'i vevela.
316 ma le 317 u'amea u'amea o lo'o i ai le alumini, o lea la e sili atu le lelei o lo latou fa'a'a'ala'au i totonu o le gataifale ma fa'alapotopotoga fa'apisinisi fa'amalama nai lo le 304 u'amea. Faatasi ai ma i latou, 316 u'amea u'amea e iai fesuiaiga e aofia ai le u'amea u'amea u'amea maualalo 316L, u'amea u'amea maualuga-malosi 316N o lo'o i ai le nitrogen, ma le u'amea u'amea 316F e leai se totogi fa'atasi ma le maualuga o le sulfur.
321, 347 ma le 348 o uʻamea faʻamautu e faʻamautu i le titanium, niobium, tantalum ma le niobium taʻitasi, e talafeagai mo vaega uʻamea faʻaaogaina i le maualuga o le vevela. 348 o se u'amea u'amea talafeagai mo le alamanuia malosiaga faaniukilia, ma ei ai ni tapulaa faapitoa i le aofaiga o tantalum ma cobalt.
2. Aisea ua maneta foi uamea stainless?
Tali: E masani ona manatu tagata e mafai e maneta ona tosina mai le uamea e faʻamaonia ai lona lelei ma le moni. Afai e le tosina mai ai le maneta, e manatu e lelei ma moni; afai e tosina mai ai le maneta, e manatu o se mea pepelo. O le mea moni, o se auala sili ona tasi le itu, le talafeagai ma le sese e iloagofie ai.
E tele ituaiga u'amea u'amea, lea e mafai ona vaevaeina i ni vaega e tusa ai ma le fa'atulagaga fa'alapotopotoga i le vevela o le potu:
1. Austenite: pei o le 304, 321, 316, 310, ma isi;
2. Martensite poʻo ferrite: pei ole 430, 420, 410, ma isi;
Austenite e le fa'amaneta pe vaivai fa'amaneta, ae o le martensite po'o le ferrite o le maneta.
O le tele o u'amea e fa'aaogaina mo pepa fa'alava teuteu o mea austenitic 304, lea e masani lava e le fa'amaneta pe vaivai vaivai. Ae ui i lea, ona o fesuiaiga o vailaʻau vailaʻau poʻo tulaga eseese o gaioiga e mafua mai i le faʻafefeteina, e mafai foi ona tupu le magnetism, ae e le mafai ona manatu o se mea taufaasese pe le agavaa. O le a le mafuaaga?
E pei ona taʻua i luga, o le austenite e le maneta pe vaivai vaivai, ae o le martensite poʻo le ferrite o le maneta. Ona o le vavaeeseina o vaega poʻo le le lelei o togafitiga vevela i le taimi o le faʻafefeteina, o se vaega laʻititi o martensite poʻo ferrite fausaga o le a mafua mai i austenitic 304 stainless steel. I lenei auala, 304 uʻamea uʻamea o le ai ai vaivai maneta.
E le gata i lea, pe a maeʻa le malulu, o le faʻatulagaina o le 304 stainless steel o le a suia foi i martensite. O le tele o le malulu galue deformation, sili atu martensite suiga, ma sili atu le maneta o le sila. Mo se faʻataʻitaʻiga, o se vaega o fasi uʻamea, pe a gaosia Φ76 tubes, e leai se faʻaogaina faʻamaneta manino, ma pe a gaosia Φ9.5 tubes. E sili atu ona manino le induction mageta ona o le tele o le malulu o le pi'o fa'aletonu. O le deformation o sikuea ma rectangular tubes e sili atu nai lo le lapotopoto tubes, aemaise lava tulimanu, ma le deformation e sili atu le malosi ma le magnetism e sili atu ona manino.
Ina ia faʻaumatia atoa le maneta o le 304 uamea e mafua mai i mafuaʻaga o loʻo taʻua i luga, e mafai ona faʻaaogaina togafitiga fofo malulu maualuga e toe faʻaleleia ai le fausaga austenite mautu, ma faʻaumatia ai le magnetism.
E tatau ona faʻamaonia faʻapitoa e faapea o le maneta o le 304 uamea e mafua mai i mafuaʻaga o loʻo i luga e matua ese lava mai le maneta o isi mea e pei o le 430 ma le carbon steel, o lona uiga, o le maneta o le 304 uamea e faʻaalia ai le vaivai.
O lenei mea e taʻu mai ia i tatou afai e vaivai le maneta pe leai foi se maneta, e tatau ona faʻamasinoina o le 3-4 poʻo le 316 mea; afai e tutusa ma le maneta o carbon sila, e faaalia ai le malosi maneta, o lea e faamasinoina e le 304 mea.
Matou te fautua atu pe a faʻatau oloa uʻamea uʻamea, e tatau ona e filifilia oloa mai tagata gaosi oloa taʻutaʻua, aua le matapeʻapeʻa mo taugofie, ma faʻaeteete i le faʻaseseina.
