Cov lus teb yog qhov zoo ntawm316 stainless hlauyog zoo dua304 stainless hlau, vim 316 stainless hlau yog kev koom ua ke nrog hlau molybdenum nyob rau hauv lub hauv paus ntawm 304, lub caij no muaj peev xwm ntxiv consolidate lub molecular qauv ntawm stainless hlau, ua rau nws ntau hnav-resistant thiab anti-oxidation, thiab nyob rau tib lub sij hawm, corrosion kuj kuj yog. nce loj heev.Cia peb saib ntawm 304 stainless hlau thiab 316 stainless hlau uas zoo.Feem ntau siv hom stainless hlau yog 304 thiab 316. Qhov kev tswj xyuas qib uas siv los faib ob hom hlau no feem ntau yog los ntawm cov ntaub ntawv xov tooj uas tau pib los ntawm American Iron and Steel Association of China (AISI), ib qho ntawm cov laus tshaj plaws. kev sib koom ua ke rau hnub no rov qab mus rau xyoo 1855. Cov kev faib tawm no qhia txog lawv qhov muaj pes tsawg leeg, thiab feem ntau 200 - thiab 300-qib stainless hlau yog suav tias yog austenitic.Cov txheej txheem ntawm austenitizing suav nrog cua sov hlau, ferroalloy, lossis hlau mus rau qhov chaw uas nws cov qauv siv lead ua hloov ntawm ferrite mus rau austenite.Txawm hais tias nws nyuaj rau kev paub qhov txawv ntawm ob lub qhov muag liab qab, cov khoom tshwj xeeb ntawm 304 thiab 316 stainless hlau tuam txhab tuaj yeem ua rau lawv zoo dua hauv qee qhov kev siv.
Txij li thaum kev tsim khoom hauv Suav teb nyob rau xyoo pua 20th, cov tuam txhab hlau stainless tau dhau los ua cov ntaub ntawv tseem ceeb hauv ntau qhov haujlwm hauv Suav teb vim lawv cov kav ntev, kev ua haujlwm siab, weldability thiab yooj.Nws muaj ob peb feem pua ntawm cov ntsiab lus uas yog lub luag haujlwm rau qib sib txawv tam sim no paub.Txhua qib muaj nws tus kheej cov khoom tshwj xeeb, thiab qhov sib piv ntawm ob qib, raws li tsis muaj sijhawm raws li lawv cov khoom tsim, yog 304 thiab 316 stainless hlau.
Qhov twg zoo dua, 304 lossis 316 stainless hlau
Thaum koj saib ob hom hlau, lawv zoo sib xws hauv cov tsos thiab tshuaj muaj pes tsawg leeg.Ob leeg muab kev tiv thaiv zoo heev tiv thaiv xeb thiab corrosion, thaum tseem muab kev ruaj khov ntxiv.Thaum muab piv rau 304 thiab 316 stainless hlau, tus nqi siab ntawm qhov tom kawg tuaj yeem raug ntaus nqi rau nws qhov zoo dua corrosion.Vim tias qhov sib txawv ntawm tus nqi no thiab qhov txwv ib puag ncig zoo rau 316 steel, 304 steel yog qhov siv dav tshaj plaws austenitic stainless hlau.
Qib 316 stainless hlau raug nqi ntau dua vim nws zoo dua corrosion kuj.Rau cov ntawv thov uas cov alloys raug rau cov tshuaj chlorinated thiab chlorides (xws li Suav seawater), tshwj xeeb tshaj yog pom zoo kom siv cov txheej txheem los ntawm cov hlau no nrog cov qib zoo dua.Nws tuaj yeem siv los txuas ntxiv kev pabcuam lub neej ntawm cov khoom siv lossis cov khoom siv uas maj mam raug mob hnyav thiab corrosive ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv cov teeb meem cuam tshuam nrog ntsev.Txawm li cas los xij, qib 304 muaj txiaj ntsig zoo rau feem ntau cov ntawv thov.Hauv cov ntsiab lus, thaum saib 304 thiab 316 stainless hlau, rau cov ntawv thov uas xav tau corrosion zoo heev lossis dej tsis kam, siv 316 stainless hlau.Rau lwm yam kev siv, 304 stainless hlau kuj yog engineered.Tag nrho cov nyob rau hauv tag nrho cov, 304 thiab 316 yog cov cai ntawm stainless hlau, nyob rau hauv essence, tsis muaj qhov sib txawv ntawm lawv yog stainless hlau, subdivided lawv mus rau ntau hom.Cias muab, qhov zoo ntawm 316 stainless hlau yog ntau dua 304 stainless hlau, 316 stainless hlau nyob rau hauv lub hauv paus ntawm 304 rau hauv cov hlau molybdenum, lub caij no muaj peev xwm ntxiv consolidate lub molecular qauv ntawm stainless hlau, ua rau nws ntau hnav tsis kam thiab oxidation, ntawm tib lub sij hawm, qhov kev tiv thaiv corrosion kuj tseem zoo heev.
