201 stainless hlau hlau nplaum tuaj yeem nqus tau

Stainless hlau yog ntau thiab nrov nrog cov neeg vim nws zoo nkauj tsos, corrosion kuj, thiab qhov zoo ntawm tsis yooj yim puas. Muaj ntau thiab ntau qhov chaw uas cov hlau tsis muaj hlau siv hauv cov lauj kaub thiab cov lauj kaub, cov duab puab hauv nroog, cov tsev, thiab cov chav dai kom zoo nkauj, tab sis tib neeg tsis muaj kev nkag siab tob txog kev txheeb xyuas cov hlau tsis huv. Thaum yuav cov khoom siv hauv chav ua noj stainless hlau, qee cov neeg siv khoom sim siv cov hlau nplaum ntawm cov khoom siv stainless hlau. mus. Nws yog ntseeg hais tias dab tsi cov hlau nplaum attracts yog stainless hlau, thiab dab tsi yuav attracted yog stainless hlau. Nws zoo nkaus li tias tib neeg tseem muaj kev nkag siab tsis zoo txog stainless hlau.
Hlau thiab hlau yog txawv los ntawm lawv cov ntsiab lus carbon. Hlau-carbon alloys nrog cov ntsiab lus carbon tsawg dua 2 feem pua ​​​​yog hu ua hlau, thiab cov uas muaj cov ntsiab lus carbon ntau dua 2 feem pua ​​yog hu ua hlau. Hlau yog dav siv vim nws toughness, elasticity thiab rigidity. Txhua yam koj tau ntsib hauv lub neej yog hlau, tab sis tib neeg hu nws txawv. Rau cov hlau tsis muaj hlau, txawm tias cov hlau nplaum nyiam los yog tsis, tsuav nws ua tau raws li cov qauv zoo, nws yog stainless hlau. Yog li ntawd, los ntawm kev xav ntawm metallurgy, tsis muaj ib yam zoo li cov hlau tsis muaj hlau.
Lub ntsiab tseem ceeb rau corrosion kuj ntawm stainless hlau yog chromium. Hlau nrog cov ntsiab lus chromium saum toj no 10.5 feem pua ​​yuav tsis xeb. Cov ntsiab lus alloying ntxiv thaum smelting yog txawv, yog li muaj qhov sib txawv ntawm seb cov hlau nplaum tuaj yeem nqus tau los yog tsis. Stainless hlau feem ntau muab faib raws li lub koom haum qauv, uas yuav muab faib ua ob peb pawg xws li austenite, ferrite, thiab martensite. Yog tias sib txawv ntawm chromium thiab npib tsib xee ntxiv rau cov hlau molten, cov hlau austenitic uas ua los ntawm stainless hlau tsis tuaj yeem nyiam los ntawm cov hlau nplaum; Yog hais tias chromium thiab ib qho me me ntawm npib tsib xee (lossis tsis muaj npib tsib xee) ntxiv rau cov hlau molten, cov hlau tsim yog Ferritic stainless hlau uas nyiam cov hlau nplaum; Lub ntsiab alloying ntsiab ntawm martensitic stainless hlau yog chromium, hlau thiab carbon. Muaj ntau tshaj 100 hom stainless hlau vim qhov sib txawv ntawm cov ntsiab lus alloy. Tag nrho tsuas yog austenitic stainless hlau yog hlau nplaum.
Lub reserves ntawm npib tsib xee nyob rau hauv lub ntiaj teb no yog heev me me, thiab tus nqi kuj kim heev. Yog li ntawd, tus nqi ntawm stainless hlau nrog cov ntsiab lus nickel siab kuj yog siab dua hauv kev ua lag luam, thiab cov hlau nplaum tsis tuaj yeem nyiam. Qhov tseeb, muaj lwm hom stainless hlau hlau nplaum uas tsis tuaj yeem nyiam. Qhov ntawd yog stainless hlau nrog cov ntsiab lus siab manganese thiab me ntsis nickel lossis tsis muaj npib tsib xee. Tus nqi lag luam ntawm cov hlau tsis zoo no yog ntau dua 1, 000 yuan ib tuj qis dua cov hlau tsis muaj hlau nrog cov ntsiab lus nickel siab. Qee tus neeg muag khoom tsuas yog siv kom zoo dua ntawm cov neeg tsis to taub tias "zoo stainless hlau hlau nplaum tsis tuaj yeem nyiam nws" los ntxias cov neeg siv khoom, thiab tus nqi yog kim li high-nickel stainless hlau.
Muaj ntau tshaj 100 hom stainless hlau, nrog cov yam ntxwv sib txawv thiab kev ua haujlwm. Feem ntau, austenitic stainless hlau yog siv rau kev kho kom zoo nkauj, toj roob hauv pes thiab duab puab. Vim tias austenitic stainless hlau muaj cov thermal conductivity tsawg, nws tsis tsim nyog siv nws ua lub lauj kaub, kib, lossis mov ua mov. Nws yuav nkim lub zog thiab ncua sij hawm rau boiling dej thiab ua noj. Siv ferritic stainless hlau los ua cov lauj kaub kib thiab cov mov nplej tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev, tab sis kuj nws cov thermal conductivity yog ze li ntawm ib nrab ntawm austenitic stainless hlau. Lub thoob sab hauv ntawm lub tshuab ntxhua khaub ncaws, lub rhaub dej, zaub ntxhua khaub ncaws, thiab lwm yam, tsuav yog cov khoom siv hauv kev sib cuag nrog dej yuav tsum tau ua los ntawm ferritic stainless hlau. Qee cov neeg yws yws tias cov riam stainless hlau tsis nrawm, thiab qhov no yog vim qhov tsis ncaj ncees lawm stainless hlau. Austenitic stainless hlau tsis tuaj yeem hardened thiab tsis haum rau riam thiab txiav cov cuab yeej. Riam ua los ntawm martensitic stainless hlau tuaj yeem hloov qhov hardness ntawm stainless hlau los ntawm kev kho cua sov, xws li quenching thiab tempering.
