SS316, a well-known stainless steel grade, is highly regarded in industries such as chemical processing, marine engineering, and medical equipment for its exceptional corrosion resistance, especially in harsh environments. Cov lus nug nquag hauv cov khoom siv tau yog: yog SS316 ib co hlau qis? Lo lus teb tsis muaj. SS316 belongs rau qeb ntawm cov hlau loj, thiab muaj qhov sib txawv ntawm nws thiab cov ntsiab lus me me ntawm alloy keeb kwm, kev ua txuj ci, thiab cov lus txhais ua ke.
Txhawm rau kom paub meej txog qhov no, peb xub xeem cov ntsiab lus tseem ceeb ntawm cov steel hlau tsawg thiab hlau alloy. Tsawg alloy steel txhais tau hais tias alloy steel keeb kwm cov ntsiab lus tsawg dua 5%, thiab cov alloy alloy cov khoom siv xws li lub zog thiab tawv. High Alloy Alloy Steel, ntawm qhov tod tes, muaj tag nrho cov txheej txheem alloy yog feem ntau ntxiv rau kev ua haujlwm tshwj xeeb ntawm 8%), thiab cov qauv tshuaj tiv thaiv corrosion, kub tsis kam, lossis hnav tsis kam.
SS316 stainless hlau deb tshaj li lub alloy keeb kwm cov ntsiab lus ntawm cov hlau qis. Nws cov ntsiab lus loj xws li chromium (16%- 18%), npib tsib {%), thiab molybdenum (2% {%). Tag nrho cov ntsiab lus ntawm cov aluminium ntsiab no muaj ntau dua 5%, uas tau ua tiav cov lus txhais ntawm cov hlau siab siab. Ntawm lawv, chromium yog lub ntsiab lus tseem ceeb rau SS316 los tsim zaj duab xis oxide oxide rau saum npoo, uas yog qhov tseem ceeb ntawm nws corrosion tsis kam; npib tsib xee txhim kho nws cov kev nruj thiab ductility; Molybdenum txuas ntxiv txhim kho nws txoj kev tiv thaiv kom pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride {{}} muaj ib puag ncig. Cov alloy cov ntsiab lus tau ntxiv rau ua kom tiav corrosion tsis kam, uas yog qhov sib txawv ntawm kev ntxiv cov khoom siv hlau tsawg (feem ntau yog txhim kho cov khoom siv txhua yam).
Los ntawm cov kev pom ntawm kev ua tau zoo kev paub txog kev ua tau zoo, SS316 thiab qis alloy steel kuj pom pom qhov sib txawv. Tsawg Alloy Steel tsom rau kev ua kom zoo dua cov khoom xws li muaj lub zog, hardness, thiab tawv thaum tswj cov nqi ntau lawm. Piv txwv li, 4130 cov hlau nplaum qis, tom qab kev kho cua sov, tuaj yeem tau txais cov khoom muaj zog thiab yog siv dav hauv cov txheej txheem uas xav tau bread {{}} bearing. SS316, raws li ib tug loj alloy stainless hlau, yuav siv corrosion tsis kam raws li nws cov ntse dua. Txawm hais tias nws tseem muaj qee lub zog cov cuab yeej (tensile muaj zog feem ntau 515 - 690 mpa mpa mpa), nws lub zog tsis yog nws lub hom phiaj tsim qauv. Nyob rau hauv ntau cov lus thov cov xwm txheej, xaiv ntawm SS316 feem ntau yog raws li nws lub peev xwm tiv thaiv corrosion, ntau dua li nrhiav lub zog tawm.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, qhov sib txawv ntawm ob kuj tseem tseem ceeb. Tsawg cov ntaub ntawv qis hlau feem ntau siv rau kev tsim khoom machinery, tsim kho cov tsheb lag luam uas tsis tshua muaj zog tsis muaj zog tab sis muaj zog. SS316 yog siv ntau dua nyob rau hauv ib puag ncig nrog kev pheej hmoo siab, xws li cov khoom siv marine, cov khoom siv tshuaj lom neeg, thiab cov khoom siv kho mob uas xav tau nquag tua pov tseg. Qhov sib txawv no hauv daim ntawv thov yog qhov tseem ceeb txiav txim siab los ntawm lawv cov sib txawv tagnrho li cas thiab kev ua tau zoo tus yam ntxwv.
Nws yog tsim nyog sau cia tias qee tus neeg tuaj yeem ua rau muaj kev ntxhov siab los ntawm ob qho tib si muaj cov ntsiab lus sib txawv, tab sis qhov sib txawv tseem ceeb ntawm cov ntsiab lus thiab kev ua haujlwm ntawm alloy cov ntsiab. Cov alloy cov ntsiab lus hauv cov khoom siv hlau tsawg yog "ib qho kev ua tiav" txhawm rau txhim kho cov khoom siv cov khoom siv hauv SS316 yog "Core" kom ua tiav cov kev ua haujlwm tshwj xeeb (corrosion tsis kam). Qhov sib txawv no ua rau lawv cov kev faib tawm hauv cov khoom siv sib txawv.
Hauv kev xaus, SS316 tsis yog cov hlau nplaum tsawg tab sis ib qho siab coens hlau stainless. Nws cov ntsiab lus siab ntawm cov ntsiab lus siab (deb tshaj 5%), Kev tsom xam rau corrosion tsis kam), thiab cov ntawv thov txhua yam los ntawm cov hlau me me. Nkag siab txog kev faib tawm no yog qhov tseem ceeb rau kev xaiv cov ntaub ntawv xaiv rau hauv cov kev thov ua tau zoo ntawm SS316, thiab zam kev tsis to taub hauv cov khoom xaiv.
