Stainless hlau yog ib hom hlau alloy uas muaj hlau ua ib qho ntawm nws cov khoom tseem ceeb, nrog rau chromium, npib tsib xee, thiab lwm yam khoom. Seb los yog tsis stainless hlau yog hlau nplaum nyob ntawm nws cov muaj pes tsawg leeg thiab txoj kev nws tau ua tiav.Tsis yog txhua hom stainless hlau yog hlau nplaum. Muaj cov hlau nplaum thiab cov hlau tsis sib nqus, nyob ntawm qhov muaj pes tsawg leeg.
Dab tsi yogstainless hlau?
Stainless hlau yog ib qho corrosion-resistant alloy ntawm hlau, chromium, thiab feem ntau lwm yam xws li npib tsib xee, molybdenum, los yog manganese. Nws yog hu ua "stainless" vim hais tias nws tiv taus staining thiab corrosion, ua rau nws yog ib qho kev xaiv nrov rau ntau yam kev siv uas muaj zog thiab ua haujlwm rau ib puag ncig yam tseem ceeb.Stainless steel resists tarnishing thiab xeb vim cov ntsiab lus muaj nyob rau hauv: hlau, chromium, silicon, carbon, nitrogen, thiab manganese. Nws yuav tsum muaj tsawg kawg yog 10.5% chromium thiab feem ntau 1.2% carbon kom pom tau tias yog stainless hlau.
Hom stainless hlau
Stainless hlau los ntawm ntau hom lossis qib, txhua tus muaj nws tus kheej muaj pes tsawg leeg thiab cov khoom. Cov qib no tau muab faib ua tsib tsev neeg loj:
1.Austenitic Stainless Hlau (300 Series):Austenitic stainless hlau yog hom ntau tshaj plaws thiab paub txog nws cov khoom tsis sib nqus, zoo heev corrosion kuj, thiab zoo formability.
2.Ferritic Stainless hlau (400 Series):Ferritic stainless hlau yog hlau nplaum thiab muaj qhov zoo corrosion kuj, txawm tias nws tsis zoo li corrosion-resistant li austenitic stainless hlau.Cov qib muaj xws li 430 thiab 446.
3.Martensitic Stainless Hlau (400 Series):Martensitic stainless hlau kuj yog sib nqus thiab muaj zog zoo thiab hardness. Nws yog siv rau hauv cov ntawv thov uas hnav tsis kam thiab hardness yog qhov tseem ceeb. Cov qhab nia muaj xws li 410 thiab 420.
4.Duplex Stainless Hlau:Duplex stainless hlau muab cov khoom ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Nws muaj kev tiv thaiv corrosion zoo heev thiab lub zog siab. Cov qhab nia muaj xws li 2205 thiab 2507.
5.Precipitation-Hardening Stainless hlau:Precipitation-hardening stainless hlau tuaj yeem kho cua sov kom ua tiav lub zog siab thiab hardness. Cov qib feem ntau suav nrog 17-4 PH thiab 15-5 PH.
Dab tsi ua rau stainless hlau magnetic?
Stainless hlau tuaj yeem yog hlau nplaum lossis tsis yog hlau nplaum, nyob ntawm nws qhov tshwj xeeb muaj pes tsawg leeg thiab microstructure.Stainless hlau hlau nplaum ntawm stainless hlau nyob ntawm nws cov qauv crystalline, muaj cov ntsiab lus alloying, thiab nws cov keeb kwm ua tiav. Austenitic stainless hlau feem ntau tsis sib nqus, thaum ferritic thiab martensitic stainless hlau feem ntau yog sib nqus. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias tuaj yeem muaj kev hloov pauv hauv txhua pawg raws li cov txheej txheem tshwj xeeb alloy thiab cov txheej txheem tsim khoom.
