Stainless hlau yog a hlau alloy, ua los ntawm hlau sib xyaw nrog cov khoom xws li chromium, nickel, molybdenum, silicon, aluminium, thiab carbon. Hlau sib xyaw nrog carbon los tsim hlau yog lub ntsiab ntawm stainless hlau . Chromium ntxiv rau ua nws resistant rau xeb.
Raws li, dab tsi ntxiv rau cov hlau ua kom nws nyuaj?
Ntxiv carbon rau hlau los ua steel ua ua kom muaj zog thiab tougher, mus txog rau ib qho point. Ces nws yuav tau muaj zog dua tab sis tsawg tawv (xws li cam khwb cia hlau ). Carbon ntxiv dag zog hlau los ntawm distorting nws crystal latice. Titanium thiab vanadium yuav hardened los ntawm carbon, tab sis tej zaum yuav ua brittle los yog txawm softer los ntawm nws.
Tom qab ntawd, lo lus nug yog, vim li cas peb ntxiv cov ntsiab lus alloying rau hlau? Alloying cov ntsiab lus yog muab tso rau hauv hlau rau ib qho, lossis ntau dua, ntawm cov laj thawj hauv qab no: (1) txhawm rau txhim kho cov khoom siv kho tshuab los ntawm kev tswj cov hardenability thiab tso cai rau qhov kub thiab txias dua thaum tuav lub zog siab thiab ductility; (2) txhawm rau txhim kho cov khoom siv hluav taws xob siab lossis qis qis; (3) rau
Ib yam li ntawd, chromium ntxiv rau hlau li cas?
Manganese (Mn): Manganese yog ntxiv rau hlau txhawm rau txhim kho kev ua haujlwm kub thiab ua kom lub zog, toughness thiab hardenability. Chromium (Cr): Chromium yog ntxiv rau hlau kom muaj zog tiv thaiv oxidation. Qhov kev tiv thaiv no nce ntxiv chromium yog ntxiv.
Dab tsi ntxiv rau cov hlau?
Stainless hlau Alloying Elements
- Cov pa roj carbon. Carbon thiab hlau yog alloyed ua ke los ua hlau.
- Manganese. Qhov sib ntxiv ntawm manganese rau hlau txhim kho kev ua haujlwm kub thiab ua kom muaj zog, lub zog, thiab hardenability.
- Chromium. Chromium yog ua ke nrog hlau los txhim kho nws txoj kev tiv thaiv oxidation.
- Nickel.
- Molybdenum.
- Nitrogen.
- Tooj.
- Titanium.

Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Vim li cas nickel ntxiv rau stainless hlau?
Nickel yog qhov tseem ceeb ntawm kev sib koom tes hauv 300 series stainless hlau qib. Lub xub ntiag ntawm npib tsib xee tshwm sim hauv kev tsim cov qauv "austenitic" uas muab cov qib no lawv lub zog, ductility thiab toughness, txawm nyob rau ntawm qhov kub thiab txias. Nws kuj ua rau cov khoom tsis sib nqus
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Dab tsi ua rau cov kaum sab nrauv ntxiv ntxiv rau?
Yog hais tias lub transversal txiav hla cov kab sib txuas (cov ntaub ntawv li niaj zaus) ces cov ces kaum sab nrauv yog ntxiv (ntxiv rau 180 °). Yog li hauv daim duab saum toj no, thaum koj txav cov ntsiab lus A lossis B, ob lub kaum sab xis qhia ib txwm ntxiv rau 180 °
