Qhov sib txawv tseem ceeb ntawm Hastelloy thiab stainless hlau yog Hastelloy qhia tau hais tias muaj kev tiv thaiv corrosion zoo piv rau stainless hlau.
Alloys yog cov sib xyaw ntawm cov tshuaj sib txawv, suav nrog cov hlau ua cov khoom tseem ceeb thiab cov hlau tsis muaj hlau ua cov khoom me me. Hastelloy thiab stainless hlau yog ob hom alloys uas paub zoo rau lawv cov kev tiv thaiv corrosion zoo heev. Txawm li cas los xij, Hastelloy tau suav tias yog qhov ua tau zoo dua rau kev tiv thaiv corrosion ntau dua li cov hlau tsis muaj steel vim nws qhov tshwj xeeb muaj pes tsawg leeg, uas muaj ntau nickel hauv nws.
Hastelloy yog dab tsi?
Hastelloy yog nickel-raws li alloy uas qhia tau zoo heev corrosion kuj. Peb hu nws ua superalloy vim tias nws tuaj yeem tiv taus qhov kub thiab txias, kev nyuaj siab, thiab feem ntau oxidizing cua. Cov khoom no muaj nyob rau hauv daim ntawv ntawm phaj, ntawv, bar, yeeb nkab, raj, thiab lwm yam. Qee yam tseem ceeb ntawm cov hlau no yog raws li nram no:
Properties of Hastelloy
- High resistance to stress
- Zoo corrosion kuj
- Txoj kev nyuaj siab corrosion cracking kuj
- siab tiv taus acids
- Yooj yim ntawm vuam
- Yooj yim ntawm kev tsim
- siab tiv thaiv oxidation (ntawm qhov kub siab)

Feem ntau, cov hlau no yog npaj los ntawm npib tsib xee, nrog rau feem pua me me ntawm lwm cov ntsiab lus xws li chromium thiab molybdenum. Kev tsim khoom yog cov txheej txheem nyuaj uas suav nrog kev sib xyaw ntawm cov khoom xyaw yooj yim nrog ntau yam tshuaj lom neeg xws li tungsten, carbon, titanium, aluminium, manganese, tooj liab, cob alt, chromium thiab lwm yam. Cov kev lag luam uas siv Hastelloy suav nrog kev lag luam tshuaj lom neeg, aerospace, kev lag luam tshuaj, thiab lwm yam.
Stainless Hlau yog dab tsi?
Stainless hlau yog cov hlau alloy uas muaj cov ntsiab lus chromium siab. Yog li ntawd, nws muaj zoo corrosion kuj. Feem ntau, cov hlau no muaj txog 10.5% chromium thiab 1.2% carbon los ntawm qhov hnyav ntawm cov hlau. Nrog nce chromium cov ntsiab lus, lub corrosion kuj kuj nce. Tsis tas li ntawd, qhov sib ntxiv ntawm qee qhov molybdenum rau hauv qhov sib xyaw no tuaj yeem ua rau muaj zog tiv thaiv acids. Stainless hlau muaj nyob rau hauv daim ntawv, daim hlau, tuav, xov hlau, raj, thiab lwm yam.

Cov txheej txheem ntawm cov hlau tsis muaj steel muaj ntau cov kauj ruam tseem ceeb: melting thiab casting, sib sau, kho cua sov, descaling, txiav thiab xov. Tsis tas li ntawd, cov khoom siv tseem ceeb rau kev tsim khoom no yog hlau ore, chromium, silicon, nickel, carbon, nitrogen, thiab manganese. Los ntawm kev ntxiv ntau yam ntawm cov ntsiab lus no, peb tuaj yeem tau txais cov khoom sib txawv raws li qhov xav tau. Piv txwv li, ntxiv nitrogen ntxiv yuav ua rau kom lub zog tensile.
Qhov txawv ntawm Hastelloy thiab Stainless Hlau yog dab tsi?
Hastelloy yog nickel-raws li alloy uas qhia tau hais tias zoo heev corrosion kuj thaum stainless hlau yog ib tug alloy ntawm hlau nrog ib tug siab chromium cov ntsiab lus thiab yog li ntawd ib tug zoo corrosion kuj. Ntxiv mus, qhov sib txawv tseem ceeb ntawm Hastelloy thiab stainless hlau yog tias Hastelloy qhia tau hais tias muaj kev tiv thaiv zoo tshaj plaws hauv kev sib piv rau stainless hlau. Ntxiv mus, cov khoom tseem ceeb ntawm Hastelloy yog npib tsib xee, chromium thiab molybdenum thaum lub ntsiab tseem ceeb ntawm stainless hlau yog hlau, chromium thiab carbon.
Thaum xav txog cov ntawv thov ntawm cov ntaub ntawv no, Hastelloy yog siv hauv kev lag luam xws li kev lag luam tshuaj lom neeg, aerospace, kev lag luam tshuaj, thiab lwm yam. whereas stainless hlau yog siv nyob rau hauv architecture, kav dej, pulp thiab ntawv, kev lag luam tshuaj, kev lag luam zaub mov thiab dej haus, thiab lwm yam.
Summary – Hastelloy vs Stainless hlau
Hauv luv luv, Hastelloy thiab stainless hlau yog cov khoom siv hlau. Hastelloy yog superalloy thaum stainless hlau yog hlau alloy. Ob qho tib si no tiv taus corrosion, tab sis qhov kev tiv thaiv yog txawv ntawm ib leeg. Hauv kev xaus, qhov sib txawv tseem ceeb ntawm Hastelloy thiab stainless hlau yog tias Hastelloy qhia tau hais tias muaj kev tiv thaiv corrosion zoo heev hauv kev sib piv rau stainless hlau.
