Yog lawm,C71500 Cov Khoom Taw Qhia Tshwj Xeeb Cov Kws Txiaj Ntsig{{0-} Ib qho ntawm nws cov yam ntxwv txhais, tshwj xeeb hauv cov chaw hnyav. Nws txoj kev tawm tsam los ntawm cov nyhuv synergistic ntawm tooj liab thiab npib tsib xee, uas ua rau cov yeeb yaj kiab ntom ntom, tiv thaiv kev ua kom tsis txhob muaj kev cuam tshuam ntxiv. Cov ntsiab lus tseem ceeb txog nws txoj kev ua tau zoo corrosion suav nrog:
Dej hiav txwv thiab cov dej hiav txwv ib puag ncig: C71500 muaj npe rau nws txoj kev tiv thaiv rau dej hiav txwv corrosion, thiab yaig, corrosion (tshwm sim los ntawm cov dej nrawm (los ntawm cov dej khov lossis xuab zeb hais). Tsis zoo li tus tooj liab lossis tooj dag, nws tsis ua "dezincification" (txuas biofosion) thiab tiv taus biofofling (txuas ntawm cov kab mob marine) zoo dua li ntau cov hlau. Nws yog dav siv rau dej txias dej txias, nkoj hulls, thiab offshore roj rig Cheebtsam.
Muaj kua muaj kua: Nws tiv thaiv kev xeb ntawm cov dej brackish, dej tsis qab ntsev, thiab feem ntau muaj cov txias tshaj plaws (piv txwv li, glycol - dej sib xyaw). Nws tseem tiv taus cov kua qaub me me (piv txwv li, tshuaj, huv si, alkalis, nws tsis pom zoo rau cov acidric acidic lossis oxidizing ib puag ncig (piv txwv li, nitric acid).
Atmospheric corrosion: Cov Alloy's Oxide Zaj Duab Xis tiv thaiv nws los ntawm tarnishing thiab xeb hauv noo, paug, lossis dej hiav txwv atmospheres. Nws tswj hwm cov qauv txheej txheem rau ntau caum xyoo hauv sab nraum zoov (piv txwv li, kos duab kos duab, marine kho vajtse).
Hauv cov ntsiab lus, C71500 yog ntawm feem ntau corrosion- Resistant tooj liab alsoy, tshwj xeeb}}}} raws li ib puag ncig.
C71500 lub luag haujlwm ntawm cov kab los ntawm kev sib txuas ntawmcorrosion tsis kam, kev siv zog, thiab versatility muaj zogCov. Nws cov ntsiab lus tseem ceeb muaj xws li:
Raws li thawj qhov txiaj ntsig, nws txoj kev tiv taus dej hiav txwv thiab lub aqueous corrosion eliminates qhov xav tau kev saib xyuas nquag lossis muaj kev lag luam nyob hauv marine / kev txo lub neej.
Lub zog: Nws muaj ntau dua tensile muaj zog tshaj li tus neeg tooj liab lub zog: ~ 320 mpa
Kev muaj zog: Txawm nyob ntawm cryogenic kub (piv txwv li, {{4 4}}}}} 196 qib), C71500 rau cov ntaub ntawv zoo li LNG (liquefied nkev) ua cov khoom siv.
Thaum nws coj zoo tshaj yog qis dua li cov tooj hluav taws xob dawb huv (kev ua hluav taws xob: ~ 20% I6 4}}} tooj liab alloys (piv txwv li, txhuas alloys). Qhov no ua rau nws haum rau kev hloov pauv cua sov, hluav taws xob txuas rau cov chaw ua hluav taws xob ib puag ncig, thiab cov cua sov cov khoom siv uas corrosion Kuj tseem yuav tsum tau ua.
C71500 tuaj yeem ua tau yooj yim siv cov txheej txheem hlau hlau ua:
Kev sib sau: Nws yog malastable thiab ducast, tso cai txias lossis kub, dov, khoov, khoov li cov hlab, cov ntaub ntawv thiab cov fittings.
Vuam: Nws Welds Zoo nrog cov hau kev zoo li Tig (Tungsten inert roj) thiab mig (nrog tsawg} Weld teeb meem (thaum siv cov khoom siv ua tub rog).
Ntaub: Thaum lub sij hawm nyuaj dua li cov xov tooj liab qab, nws tuaj yeem raug machined nrog cov cuab yeej carbide thiab cua txias, tab sis nws yuav xav tau qeeb qeeb txiav ua haujlwm hnyav.
Nyob rau hauv cov av marine ib puag ncig, c71500 lub saum npoo yog tsawg dua qub rau biofouling (kev loj hlob ntawm algae, los yog mussels) piv rau cov hlau lossis aluminium. Qhov no txo tau luag ntawm nkoj Hulls thiab tswj hwm ntws tawm hauv cov kav dej hiav txwv, txo hluav taws xob kev siv hluav taws xob.
Its corrosion resistance and mechanical stability translate to a long lifespan (often 30+ years in marine applications), making it a cost-effective choice despite its higher initial price than pure copper or brass.
Txawm hais tias nws qhov ua tau zoo, C71500 muaj kev txwv uas txwv nws siv hauv qee qhov xwm txheej:
Nickel yog cov hlau kim, thiab C71500 30% Nickel cov ntsiab lus ua rau nws muaj nuj nqis ntau dua li cov xim tooj liab, tooj dag, lossis txawm tias qee qhov stainless hlau. Qhov kev ntsuas siab tus nqi no tus nqi txwv nws siv nyob rau hauv qis-} Cov khoom tseem ceeb (piv txwv li {{} {siab plumbing).
Thaum nws coj ua tau txaus rau ntau daim ntawv thov, nws yog qis dua tooj liab. Rau siab -, tsev neeg siv hluav taws xob, siab}} siab}} kub alloys yog qhov ua kom muaj zog txo qis zog lossis cua sov.
C71500 ua tsis tau zoo nyob rau hauv concentrated oxidizing acids (piv txwv li, nitric acid, concentrated sulfuric acid) thiab muaj zog oxidizing cov neeg sawv cev (piv txwv li, tshuaj chlorine). Hauv cov chaw ib puag ncig, nws cov oxide zaj duab xis tawg sai sai, ua rau kev mob caj dab loj. Nws tseem tsis pom zoo rau kev siv nyob rau hauv ib puag ncig nrog cov ntsiab lus tseem ceeb ntawm cov sulfur (piv txwv li nws tuaj yeem tsim cov tooj liab loj sulfide.
Piv rau cov tooj liab lossis tooj dag, c71500 yog qhov nyuaj thiab ntau dua tus mob ua kom tawv tawv thaum lub tshuab ua haujlwm. Qhov no yuav tsum tau cov cuab yeej tshwj xeeb (piv txwv li, carbide inserts), qeeb cov cuab yeej hloov pauv, thiab cov cuab yeej nquag hloov pauv, nce kev nce ntxiv, nce kev ua kom dawb thiab cov nqi.
Thaum nws khaws tau lub zog ntawm kev kub siab (~ 200 degree), nws cov khoom siv me me thiab corrosion tiv taus degrade ntawm qhov kub tshaj 300 lij. Thaum kub siab, npib tsib xee tuaj yeem oxidize sai, thiab cov alloy tej zaum yuav muag muag lossis ua nkig. Qhov no ua rau nws tsis zoo rau siab siab- sov daim ntawv thov zoo li dav hlau cav lossis cov npe uas muaj kev lag luam (qhov twg nyiam).
Nrog lub ntom ntom ntawm ~ 8.9 g / cmà (zoo ib yam li tooj liab), c71500 yog ntau hnyav dua li txhuas alloys (~ 2.7 g / cm³ier (~ 2.7 g / cm³). Rau qhov hnyav {{4 {}} Cov ntawv thov uas xav tau (piv txwv li cov khoom siv roj ntsha)
Thaum nyob rau hauv kev sib cuag ncaj qha nrog ntau cov hlau (piv txwv li, steel, zinc) hauv cov cathode hauv lub galvanic ntawm cov hlau loj. Txhawm rau tiv thaiv qhov no, rwb thaiv tsev (piv txwv, cov pa roj carkets) lossis cov hlau uas yuav tsum tau siv, ntxiv cov nyom thiab cov nqi ua ke.
