Biphase uamea uamea
Aluia maualuga le vevela
◆F51 (31803) o le sili ona faʻaaogaina duplex uʻamea uʻamea, e masani ona faʻaaogaina i le suauʻu oona ma le gaosiga lelei o le kesi, i le faʻamamaina o le suauʻu, vailaʻau, fertilizer, petrochemical ma isi fanua, mo le gaosiga o mea vevela, condensing coolers, ma isi. lea e faigofie ona fa'a'ele'elea ma fa'amamafaina mea fa'amalosi. Nai lo le 304L, 316L austenitic uamea u'amea.
◆F53 (S32750) o se uʻamea uʻamea super duplex faʻatasi ai ma le nitrogen faaopoopo, lea e masani ona faʻaaogaina i vailaʻau, petrochemical ma gataifale e manaʻomia ai le malosi faʻapitoa ma le faʻafefe.
◆F55 (S32760) o se uʻamea uʻamea super duplex ma le malosi maualuga, maualuga tetee i chloride localized corrosion ma popole corrosion, ma weldable.
◆329 (S32900) o loʻo i ai le faʻamaʻiina lelei o le faʻamaʻiina, faʻafefeteina, malosi maualuga, ma e talafeagai mo siosiomaga e pei o le faʻafefe o le sami.
◆A4 uamea (0Cr17Mn13Mo2N) o se uamea lua-vaega, ma o lona tetee corrosion e sili atu nai lo o le uamea austenitic masani faʻaaogaina ma le anotusi Mo o 2% -3%. E mafai ona faʻaaogaina i vailaʻau faʻamaʻi laiti, mea faʻaogaina urea atoa, ma isi.
◆S31050 e maualuga le tetee i chloride stress corrosion ta'e, sili ona tetee i pitting corrosion ma crevice corrosion.
◆U3 o loʻo i ai mea faʻapipiʻi ma faʻafefete, ma e masani ona faʻaaogaina e fai ai pusa valve, nofoa valve ma isi vaega valve i totonu.
◆HD o loʻo faʻaaogaina lautele i pisinisi faʻaeletoroni, alamanuia photoelectric, alamanuia petrochemical, alamanuia o taavale ma isi pamu suauu eletise faʻatonutonu saoasaoa.
◆C4 e fetaui lelei mo mea faʻapipiʻi faʻapipiʻi tetele, faʻafefiloi, faʻafefiloi, faʻapipiʻi faʻasalalau ma isi masini masini.
◆DS-2 o loʻo i ai faʻamaʻi faʻamaʻi i le maualuga o le vevela faʻapipiʻi sulfuric acid, ma e talafeagai mo masini masini i le maualuga o le vevela faʻapipiʻi sulfuric acid alamanuia.
