mea uamea uamea:
u'amea u'amea o se ituaiga o mea, e latalata i le pupula fa'ata, pa'i malosi ma malulu, e aofia i le mea e sili atu avant-garde teuteuga mea, e sili ona lelei tete'e corrosion, molding, fetaui ma faigata ma isi faasologa uiga, faʻaaogaina i alamanuia mamafa. , alamanuia mama, alamanuia oloa fale ma fale teuteu ma isi alamanuia.
u'amea tetee uamea ua ta'ua o le uamea stainless, e aofia ai uamea stainless ma uamea tetee uamea lua vaega, i se aotelega, e mafai ona tetee corrosion ea o le uamea ua ta'ua uamea stainless, ma e mafai ona tetee i le corrosion medium vailaau o le ua ta'ua o le acid resistant steel.Generally tautala, o le chromium anotusi o Cr e sili atu nai lo le 12% o le uamea ei ai uiga o le uamea stainless.
Fa'avasegaina uamea uamea:
E tele auala o le faʻavasegaina o uʻamea uʻamea, lea e sili ona taatele o mea nei.
Fa'avasegaga fa'avasegaga:
E mafai ona vaevaeina i austenitic uʻamea uʻamea, ferrite uʻamea uʻamea, martensitic uʻamea uʻamea, duplex uʻamea uʻamea, timuga faʻamaʻaʻaina uamea.
Fa'avasegaga o vaila'au:
E mafai ona vaevaeina i totonu o le chromium stainless steel (e pei o le ferrite series, martensite system) ma le chromium nickel stainless steel (e pei o le austenite system, faʻasologa faʻafuaseʻi, faʻamaʻaina timuga) faiga e lua.
E tusa ai ma le ituaiga o le corrosion resistance:
E mafai ona vaevaeina i le u'amea fa'amamafa u'amea u'amea u'amea u'amea, pitting corrosion tete'e u'amea u'amea, intergranular corrosion tete'e uamea stainless, ma isi.
Fa'avasegaina i vaega fa'atino:
E mafai ona vaevaeina i le tipiina saoloto uamea, uamea e leai se maneta, uamea u'amea vevela maualalo, u'amea maualuga malosi.
E toetoe lava 100 ituaiga o uamea uamea ua aofia i tulaga eseese i le lalolagi, ma faatasi ai ma le alualu i luma o le faasaienisi ma tekinolosi ma le atinae o alamanuia ma faatoaga, ua faateleina foi togi uamea stainless. , o lona chromium e tutusa [Cr] ma le nickel e tutusa [Ni] e mafai ona fuafuaina e tusa ai ma lona tuufaatasiga kemikolo, ma o le microstructure ma meatotino o le uamea e mafai ona fua faatatau e ala i le faaaogaina o le Schaeffler-Delong stainless steel microstructure siata.
Fa'avasegaina matrix:
.
2. Austenitic stainless steel.It e aofia ai le sili atu i le 18% chromium, e uiga i le 8% nickel ma se vaega itiiti o le molybdenum, titanium, nitrogen ma isi elemene. Lelei atoatoa faatinoga, corrosion tetee i le tele o ala o faasalalauga.
3. Austenite-ferrite duplex uʻamea uʻamea. E i ai le lelei o austenite ma ferrite uʻamea uʻamea, ma e superplasticity.
Martensitic stainless steel.High malosi, ae le lelei plasticity ma weldability.
uamea uamea tulaga faatonuina laulau faatusatusa numera ma laulau density
