321 fa'alava uamea u'amea 304 304L 316 316L 310S 321 Ss fa'apa'au fa'alava fa'au'u u'amea u'amea
Fa'amatalaga
321 Uamea u'amea ose austenitic u'amea uamea e fa'amautu i le titanium.O le 321 o loʻo iai foʻi le chromium faʻapea foʻi ma le nickel ma faʻaopopo i le titanium, e maua ai le faʻaleleia atili o le faʻafefe o le vaeluagalemu.321 i le le maneta w/e tutusa le pala e tetee atu i le ituaiga 304. O mea nei e fa'aaogaina mo masini uelo e le mafai ona fa'afefe.E le gata i lea, o loʻo faʻaaogaina mo masini e faʻaogaina i le va o le 800 ma le 1500 ° F.
321 o loʻo maua ile pa lapotopoto, ipu, paipa, laupepa, paipa, coil ma paipa.Mo so'o se mana'oga u'amea 321 fa'amolemole vala'au Michlin Metals.Mo nisi faʻamatalaga i lenei mea faʻapea foʻi ma isi Austenitic Stainless Steels siaki se vitio i luga o lena autu o loʻo i lalo:
321 uamea stainless seamless tubes uamea (GB3087-1999) e maualuga tulaga carbon structural uamea vevela-taavale ma malulu-tosi (taavale) paipa uʻamea seamless, lea e faʻaaogaina mo le gaosiga o paipa ausa superheated, paipa vai vai o faumea mamafa eseese ma feololo. ma paipa ausa fa'avevela, paipa asu lapopo'a, paipa asu laiti ma paipa piliki fa'akomepiuta o fa'afu locomotive.
321 faagaau u'amea u'amea: E masani ona fa'aaogaina i le gaosiga o le maualuga o le mamafa ma le sili atu o le mamafa o paipa paipa ausa, ma isi. Fa'atasi ai ma le maualuga maualuga o le carbon structural sila, uamea u'amea ma le u'amea vevela fa'afefe uamea seamless tube, o le faagaau fau e le pati i lalo o le vevela maualuga ma paipa mamafa maualuga ma galue i le vevela maualuga kasa flue ma ausa o le a tupu i lalo o le gaioiga o le oxidation ma corrosion, o lea o le paipa uʻamea ma le malosi rupture maualuga, tetee oxidation maualuga, Ma o loʻo i ai le faʻamautuina lelei o le faʻalapotopotoga, faʻapipiʻi faʻapipiʻi eletise.
321 faagaau u'amea u'amea o lo'o tu'uina atu ile tulaga vevela.E le gata i lea, e manaʻomia foʻi le microstructure, le saito ma le decarburization layer o faʻamaʻi uamea.O paipa u'amea e le fa'aogaina mo le viliina o eleele ma le fa'atonutonuina o le suau'u;Ina ia mafai ona suʻesuʻeina le fausaga o papa i lalo o le eleele, vai o le eleele, suauʻu, kesi faʻalenatura ma minerale punaoa, faʻaogaina o Vaieli eli.
