Dab tsi yog stainless hlau
Stainless hlau yog ib hom hlau alloy uas paub txog nws qhov kev tiv thaiv corrosion thiab kav ntev. Nws yog feem ntau tsim los ntawm hlau, nrog rau ntau qhov sib txawv ntawm chromium, npib tsib xee, molybdenum, thiab lwm yam. Qhov muaj pes tsawg leeg ntawm stainless hlau tuaj yeem sib txawv nyob ntawm qib tshwj xeeb thiab npaj siv.
Qhov sib ntxiv ntawm chromium yog qhov tseem ceeb rau cov hlau tsis muaj zog corrosion vim nws tsim ib txheej nyias, pob tshab oxide txheej ntawm qhov chaw, hu ua cov txheej txheem passive. Cov txheej txheem passive no tiv thaiv cov hlau hauv qab los ntawm oxidation, xeb, thiab staining los ntawm kev tiv thaiv kev sib cuag nrog oxygen thiab ya raws.
Stainless hlau muaj ntau yam thiab pom cov ntawv thov hauv ntau qhov kev lag luam, suav nrog kev tsim kho, tsheb, aerospace, kho mob, chav ua noj, thiab ntau ntxiv. Nws txoj kev tiv thaiv corrosion, lub zog, thiab kev zoo nkauj ua rau nws muaj kev xaiv nrov rau cov khoom xws li cov tais diav, khoom siv, thiab cookware rau txuas hniav, vaj tse, thiab cov cuab yeej phais.
Stainless hlau kuj muaj nyob rau hauv ntau qib lossis hom, txhua qhov muab cov khoom tshwj xeeb haum rau cov ntawv thov tshwj xeeb. Cov qib no raug cais raws li lawv cov tshuaj muaj pes tsawg leeg, xws li cov chromium thiab npib tsib xee tam sim no. Qee cov qib stainless hlau muaj xws li 304, 316, 430, thiab 17-4 PH.
Zuag qhia tag nrho, stainless hlau tsis kam tiv thaiv corrosion, tshav kub, thiab staining, ua ke nrog nws lub zog thiab kev zoo nkauj, ua rau nws siv ntau yam khoom siv hauv kev lag luam thiab cov khoom siv niaj hnub.
Stainless hlau qib
Stainless hlau muaj nyob rau hauv ntau qib, txhua tus ntawm nws muaj nws tus kheej cov tshuaj muaj pes tsawg leeg thiab cov khoom. Nov yog qee cov qib stainless hlau feem ntau siv:
1, Austenitic Stainless hlau:
- 304 (tseem hu ua 18/8 stainless hlau): Nws muaj 18 feem pua chromium thiab 8 feem pua nickel, muab kev tiv thaiv zoo corrosion, zoo heev formability, thiab siab ductility. Nws yog feem ntau siv hauv cov khoom siv hauv chav ua noj, cov khoom siv ua zaub mov, thiab kev siv vaj tse.
- 316 (tseem hu ua marine qib stainless hlau): Nws muaj 16-18 feem pua chromium, 10-14 feem pua npib tsib xee, thiab 2-3 feem pua molybdenum, muab kev txhim kho corrosion, tshwj xeeb tshaj yog tiv thaiv chloride ib puag ncig. Nws feem ntau yog siv rau hauv kev siv marine, kev ua tshuaj, thiab kev kho mob cog.
2, Ferritic Stainless hlau:
- 430: Nws muaj 16-18 feem pua chromium thiab cov ntsiab lus nickel tsawg. Nws muaj zoo corrosion kuj, siab thermal conductivity, thiab zoo heev formability. Nws yog feem ntau siv rau hauv cov tais diav hauv chav ua noj, cov khoom siv hauv tsheb, thiab kev siv architectural.
3, Martensitic Stainless hlau:
- 410: Nws muaj 11. Nws yog feem ntau siv rau hauv daim ntawv thov xws li cutlery, cov cuab yeej phais, thiab li qub.
4, Duplex Stainless Hlau:
- 2205: Nws muaj 22 feem pua chromium, 5-6 feem pua npib tsib xee, thiab 3 feem pua molybdenum. Nws muaj qhov sib npaug sib npaug ntawm lub zog siab thiab corrosion kuj. Nws feem ntau yog siv rau hauv kev lag luam tshuaj, roj thiab roj, thiab cov khoom siv hluav taws xob.
5, Precipitation-Hardening Stainless Steels:
- 17-4 PH: Nws muaj li ntawm 17 feem pua chromium, 4 feem pua nickel, thiab 4 feem pua tooj liab, nrog rau lwm cov khoom me me. Nws tuaj yeem kho cua sov kom ua tiav lub zog siab thiab tawv, ua rau nws tsim nyog rau kev lag luam aerospace, nuclear, thiab tshuaj lom neeg kev lag luam.
Cov no tsuas yog qee qhov piv txwv ntawm ntau qib stainless hlau muaj. Kev xaiv cov qib tshwj xeeb yog nyob ntawm cov yam ntxwv xws li cov ntawv thov, ib puag ncig, thiab cov khoom xav tau zoo li corrosion kuj, lub zog, thiab formability.
