Tam sim no nyob rau hauv Suav teb kev muag khoom ntawmstainless hlaufeem ntau yog 300 series thiab 200 series, qhov sib txawv ntawm ob yog cov khoom siv tshuaj lom neeg cov ntsiab lus nickel, uas ua rau lawv nyob rau hauv kev ua tau zoo thiab tus nqi ntawm qhov sib txawv loj.
Nyob rau theem tam sim no ntawm cov nqi npib tsib xee, cov ntsiab lus npib tsib xee qis heev 200 series stainless hlau tus nqi tsuas yog kwv yees li ib nrab ntawm 300 series stainless hlau, corrosion thiab toughness nyob rau hauv lub caij nplooj ntoos hlav kev ua tau zoo yog deb tshaj li 300 series.stainless hlau, tsuas yog muaj feem xyuam rau lub txee ua zaub mov thiab lwm yam kev lag luam, yog tias siv rau hauv kev tsim kho, cov khoom siv kho mob, thaj chaw ntawm lub pob tawb, yuav muaj kev cuam tshuam loj heev ntawm cov teeb meem zais.Nickel cov ntsiab lus ntawm kwv yees li 1% ntawm 200 series khoom, tsis tuaj yeem raug rau huab cua corrosion.
300 series stainless hlautseem hu ua 18-8 steel, yog cov fasteners, cov pob qij txha, cov hlab thiab cov kav dej feem ntau siv cov ntaub ntawv.18-8 steel yog nominal cov ntsiab lus ntawm chromium thiab npib tsib xee nyob rau hauv 300 series stainless hlau, cov ntaub ntawv nyob rau saum npoo ntawm zoo corrosion kuj, tab sis vim cov deposition ntawm carbon, nws yuav ua rau cov ntsiab lus chromium poob.Chromium ua ke nrog cov pa roj carbon ntawm qhov kub thiab txias los tsim chromium carbide, uas tsis xeb tiv taus.
400 series stainless hlau chromium cov ntsiab lus dua300 series stainless hlauTsawg, tab sis tsis zoo li 300 series muaj teeb meem carbon deposition, thiab tuaj yeem kho cua sov, tab sis vim tias cov ntsiab lus chromium tsuas yog 12% ntawm 14%, nyob rau hauv ib puag ncig ntawm cov tshuaj lom neeg hnyav yuav ua rau kev siv 300 series uas muaj 16. % ntawm 20% ntawm chromium, yuav tsis corrode.300 series stainless hlau thiab 400 series stainless hlau nyob rau hauv tib lub zog.
