Fa'aaogāga fa'apisinisi oapa silivae tusa ai ma le faalapotopotoga metallographic e mafai ona vaevaeina i ni vaega se tolu: ferritic uamea stainless, martensitic uamea stainless, austenitic uamea stainless.E mafai ona avea ma uiga o nei ituaiga e tolu o uʻamea uʻamea (e pei ona faaalia i le laulau i lalo), ae e tatau ona maitauina o le uamea stainless martensitic e le mafai ona uelo uma, ae na o nisi tulaga, e pei o le uelo e tatau ona. preheated ina ua uma le uelo e tatau ona maualuga le vevela ita ina ia sili atu ona faigata le faagasologa o le uelo.Le gaosiga moni o nisi martensitic uʻamea uʻamea e pei ole 1Cr13, 2Cr13 ma 2Cr13 ma 45 uʻamea uʻamea pe sili atu.

Ferritic u'amea u'amea e patino foi i chrome uamea
Low carbon content, anti-atmospheric, nitric acid and saline solution corrosion gafatia, maualuga vevela oxidation tetee ma isi.Fa'aaoga tele i le gaosiga o masini vaila'au i totonu o le atigipusa, paipa.

Austenitic uamea uamea ole chrome nickel uamea
E i ai le maualuga o le corrosion teteʻe, sili palasitika, lelei weldability ma maualalo vevela toughness, leai se mageta, faigofie e galue faʻamalosi.E masani ona faʻaaogaina i galuega faʻasalalau faʻaleagaina i vaega, koneteina, paipa, mea faʻafomaʻi ma le siosiomaga faʻamaneta.
