Thaum nws los txog rau kev lag luam cov ntaub ntawv, stainless hlau thiab hlau alloy steel yog ob ntawm cov feem ntau siv hom hlau. Tej zaum lawv yuav zoo sib xws thaum xub thawj siab ib muag, tab sis lawv muaj pes tsawg leeg, kev ua tau zoo, thiab kev siv yog txawv heev. Kev nkag siab txog qhov sib txawv no tuaj yeem pab koj xaiv cov khoom tsim nyog rau koj qhov project thiab zam kev ua yuam kev kim.
1. Kev sib xyaw ua ke
Qhov sib txawv tseem ceeb pib nrog lawv cov tshuaj muaj pes tsawg leeg.
Stainless hlau muaj qhov tsawg kawg nkaus ntawm 10.5% chromium, uas tsim ib txheej nyias, tsis pom ntawm qhov chaw uas tiv thaiv xeb thiab xeb. Qee qib kuj suav nrog npib tsib xee, molybdenum, lossis titanium ntxiv rau lub zog thiab kav ntev.
Alloy steel, ntawm qhov tod tes, yog carbon steel tov nrog cov ntsiab lus xws li manganese, silicon, npib tsib xee, los yog vanadium los txhim kho toughness, lub zog, los yog hnav tsis kam. Txawm li cas los xij, nws cov ntsiab lus chromium feem ntau yog qis dua 10%, yog li nws tsis zoo li corrosion-resistant li stainless hlau.
2. Corrosion Resistance
Yog tias koj xav tau cov khoom siv uas tiv thaiv xeb, stainless hlau yog qhov kev xaiv zoo dua.
Nws tiv thaiv chromium oxide zaj duab xis rov tsim dua tshiab thaum khawb, ua rau nws zoo tagnrho rau ib puag ncig nrog noo noo, tshuaj, lossis ntsev.
Alloy steel, thaum muaj zog dua nyob rau hauv qee kis, feem ntau yuav tsum tau coatings nto los yog kev saib xyuas tsis tu ncua los tiv thaiv xeb.
3. Cov tsos thiab nto tiav
Visually, stainless hlau feem ntau muaj qhov ci dua thiab muaj kev cuam tshuam ntau dua, tshwj xeeb tshaj yog tom qab polishing.
Alloy steel nyhav tshwm sim tsaus nti los yog duller, qee zaum nrog matte los yog me ntsis ntxhib tag.
Hauv kev cob qhia, ib qho kev sim yooj yim yog tso ob qho tib si hauv qab lub teeb - stainless hlau feem ntau ci kom pom tseeb dua.
4. Mechanical Properties
Alloy steel tuaj yeem tsim kho kom muaj zog thiab tawv tawv, uas ua rau nws haum rau hnyav -cov dej num xws li cov ncej, lub zog, thiab cov kav dej.
Stainless hlau muab qhov sib npaug ntawm lub zog thiab kev tiv thaiv corrosion, zoo tagnrho rau cov khoom siv hauv chav ua noj, cov tso tsheb hlau luam tshuaj, thiab marine fittings.
Kev xaiv ntawm ob yog nyob ntawm seb koj puas tseem ceeb rau kev ua haujlwm ntev lossis kev tiv thaiv corrosion.
5. Daim ntawv thov txheej txheem
Stainless hlau: Khoom noj khoom haus kev lag luam, chav ua noj, tshuaj ua, Kev tsim kho, khoom siv kho mob.
Alloy Steel: Automotive Cheebtsam, Fais fab nroj tsuag thiab refineries, Roj & roj pipelines, Machinery thiab cov cuab yeej.
6. Nqe thiab Kev Kho
Stainless hlau feem ntau kim dua vim nws cov ntsiab lus chromium thiab nickel ntau dua.
Alloy steel yog kev lag luam ntau dua, tab sis feem ntau yuav tsum tau pleev xim, txheej, lossis galvanizing los tiv thaiv corrosion hauv kev siv sab nraum zoov.
7. Cov lus qhia qhia paub yooj yim
Nov yog ob peb txoj hauv kev yooj yim los qhia lawv sib nrug:
Magnet Test: Ntau cov hlau tsis muaj hlau tsis yog- sib nqus, thaum feem ntau cov hlau tsis muaj hlau nplaum.
Kev kuaj xeb: Cia ob qho tib si rau huab cua thiab noo noo - stainless hlau nyob twj ywm kaj; alloy steel qhia cov pob zeb.
Spark Test: Thaum sib tsoo, stainless hlau ua luv luv, liab sparks; alloy steel muab tawm ci, ntev daj sparks.
Xaus
Ob leeg stainless hlau thiab alloy hlau muaj lawv tus kheej lub zog.
Yog tias koj qhov project xav tau kev tiv thaiv corrosion thiab lub ntsej muag huv si, stainless hlau yog koj mus - xaiv.
Yog tias koj xav tau lub zog txhua yam thiab cov nqi ua haujlwm, cov hlau alloy yog qhov ua tau zoo dua.
Paub qhov txawv yuav pab ua kom muaj kev ua tau zoo, kev ua haujlwm ntev, thiab kev nqis peev zoo rau koj daim ntawv thov.
