Stainless hlau thiab titanium yog cov khoom siv feem ntau siv hauv kev lag luam. Lawv muaj qhov tshwj xeeb zoo ntawm kev ua haujlwm, kev tiv thaiv corrosion thiab nqi. Ntawm lawv, stainless hlau muab faib ua peb hom: 201 stainless hlau, 304 stainless hlau thiab 316 stainless hlau. Kuj tseem muaj qee qhov sib txawv ntawm lawv.
Ua ntej ntawm tag nrho cov, 201 stainless hlau yog ib hom zoo tib yam stainless hlau uas muaj manganese, uas yog tsuas yog siv nyob rau hauv kho kom zoo nkauj sab hauv, rooj tog tsim thiab lwm yam teb. Piv nrog rau ob hom stainless hlau, 201 steel muaj zog qis dua tab sis pheej yig dua. Nyob rau hauv cov nqe lus ntawm corrosion kuj, xeb kuj ntawm 201 steel yog qis dua li ntawm 304 thiab 316 steel.
Qhov thib ob, 304 stainless hlau yog feem ntau siv stainless hlau, uas yog tsim los ntawm 18% chromium thiab 8% npib tsib xee. Hom stainless hlau no muaj qhov zoo corrosion kuj, kub tsis kam thiab weldability, thiab tus nqi kuj yog nruab nrab. Yog li ntawd, nws yog dav siv hauv kev ua zaub mov, khoom siv kho mob, khoom siv tshuaj thiab lwm yam kev lag luam.
Tsis tas li ntawd, 316 stainless hlau zoo ib yam li 304 stainless hlau, tab sis nws muaj 2% -3% molybdenum, uas muaj kev tiv thaiv corrosion zoo dua. 316 stainless hlau yog dav siv nyob rau hauv marine ib puag ncig thiab acidic ib puag ncig, thiab yog dav siv nyob rau hauv kev tsim cov khoom siv tshuaj, marine khoom thiab lwm yam teb.
Thaum kawg, titanium hlau yog lub teeb yuag, muaj zog cov khoom siv nrog corrosion zoo heev, oxidation kuj thiab biocompatibility. Yog li ntawd, nws tau siv dav hauv aerospace, khoom siv kho mob, khoom siv ncaws pob thiab lwm yam haujlwm. Txawm li cas los xij, tus nqi ntawm cov hlau titanium kuj yog qhov siab, uas yog ib qho laj thawj vim li cas nws daim ntawv thov raug txwv.
Feem ntau, 201 stainless hlau, 304 stainless hlau,316 stainless hlauthiab titanium hlau txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo hauv ntau qhov chaw. Kev xaiv cov ntaub ntawv yuav tsum xav txog ntau yam, xws li ib puag ncig, kev thauj khoom, nqi, thiab lwm yam.
