304 316L 2205 S31803 ipu uamea uamea
Fa'aaliga o oloa:
O le fa'afefeteina o le u'amea u'amea e fa'alagolago lava i lona tu'ufa'atasiga u'amea (Cr, Ni, Ti, Si, Al, Mn, ma isi) ma lona fa'alapotopotoga fa'alotoifale.
E tusa ai ma le auala gaosiga o le taʻavale vevela ma le malulu taʻavale lua ituaiga, e tusa ai ma uiga o le tino o le ituaiga uamea ua vaevaeina i 5 vaega: ituaiga austenite, ituaiga austenite-ferrite, ituaiga ferrite, ituaiga martensite, ituaiga faʻamaʻaina timuga.
lamolemole luga ole ipu u'amea uamea, e maualuga plasticity, toughness ma masini malosi, tetee i acid, alkaline kasa, fofo ma isi ala o faasalalauga corrosion.O se u'amea u'amea e le 'ele gofie.

Papatusi Tete'e La'ei, Papatusi Tetee Tau
Fa'aaliga o oloa:
O le ipu u'amea e fa'alavalava e fa'atatau i vaega e lua: o le pa'u uamea maualalo-carbon ma le fa'aofuofu fa'alava.O le fa'aofuofu fa'aofuofu fa'alava e masani lava 1 / 3 ~ 1 / 2 o le mafiafia atoa.Pe a galue, o le matrix e maua ai le faʻatinoga atoatoa e pei o le malosi, faigata ma le palasitisi, ma le faʻaofuofu faʻapipiʻi faʻapipiʻi e maua ai le faʻaofuofu-tetee e faʻafetaui ai manaʻoga o tulaga faʻapitoa o galuega.
O le fa'aofuofu fa'aofuofu fa'aofuofu e masani lava o le chromium alloy, ma le manganese, molybdenum, niobium, nickel ma isi mea fa'apipi'i fa'aopoopoina.O le carbide i totonu o le metallographic tissue e tufatufa atu i foliga alava, ma o le alava itu e sa'o i luga.Ole microhardness ole carbide e mafai ona oʻo i luga aʻe o le HV1700-2000, ma le maaa o luga e mafai ona oʻo ile HRC 58-62.Alloy carbide o loʻo i ai se faʻamautu malosi i le maualuga o le vevela, faʻamautu le maualuga o le maaa, ae o loʻo i ai foi se mea lelei antioxidant, i totonu ole 500 ℃ faʻaoga masani.

S235JR S275JR S355JR Pepa Uamea Carbon
Fa'aaliga o oloa:
O ipu uamea ua vaevaeina i papatusi vevela ma malulu.
E tusa ai ma ituaiga uʻamea, o loʻo i ai le uamea masani, uamea maualuga, uamea uʻamea, uʻamea tautotogo, uʻamea uʻamea, uʻamea meafaigaluega, uamea faʻafefe vevela, uamea faʻapipiʻi, uamea silicon ma fale gaosi oloa mama.
e mafai ona vaevaeina uamea fausaga maualuga maualuga i ni vaega se tolu e tusa ai ma mea eseese carbon: uamea maualalo carbon (C 0.25%), uamea carbon medium (C o 0.25-0.6%) ma uamea maualuga carbon (C & gt; 0.6%).
O le maualuga o le carbon structural steel ua vaevaeina i le manganese masani (0.25% -0.8%) ma le maualuga o le manganese (0.70% -1.20%), o loʻo i ai i le vaega mulimuli ni mea faʻainisinia lelei ma le gaosiga o meatotino.
