C71500 tooj liab nickel alloy
C71500, tseem hu ua tooj liab-nickel alloy, yog ib qho khoom siv tooj liab uas feem ntau suav nrog tooj liab, npib tsib xee, thiab cov hlau me me. Qhov feem ntawm tooj liab nyob rau hauv C71500 txawv ntawm 65% thiab 70%, npib tsib xee ntawm 30% thiab 35%, thiab hlau yog tam sim no nyob rau hauv me me ntawm li 0.4%. C71500 kuj tseem muaj cov lej ntawm manganese thiab silicon. Vim nws cov ntsiab lus npib tsib xee, C71500 poob rau hauv cov nickel-tooj liab alloys.
| Element | Cov ntsiab lus (%) |
|---|---|
| tooj, Cu | 70 |
| Nickel, Nia | 30 |
C71500 muaj qhov ceev ntawm 8.94 grams ib cubic centimeter, me ntsis siab dua tooj liab ntshiab. Nws muaj hluav taws xob conductivity txog li 3% IACS (International Annealed Copper Standard). Nws thermal conductivity yog 40 W / m·K, qis dua tooj liab ntshiab. C71500 nthuav tawm zoo heev tiv thaiv kev ntxhov siab corrosion tawg thiab pitting corrosion.
| Cov khoom | Metric | Imperial |

| Qhov ntom | 8.94 g / cm²3 | 0.323 lb/in3 |
| Melting point | 1171 degree | 2140 degree F |
C71500 yog dav siv nyob rau hauv marine thiab tshuaj ua lag luam. Nws zoo heev corrosion kuj yog zoo tagnrho rau seawater txias tshuab thiab marine daim ntaub ntawv. Nws lub zog siab thiab hardness ua rau nws zoo tagnrho rau lub cev valve, lub cev twj tso kua mis, thiab lwm yam kev siv tshuab siab. C71500 kuj tseem siv rau hauv cov khoom siv hluav taws xob sib hloov, condensers, thiab lwm yam kev siv uas xav tau kev hloov pauv kub zoo heev thiab tiv thaiv fouling.
C71500 muaj ib tug zoo hardness txog 120 HV, siab tshaj tooj liab ntshiab. Nws cov hardness siab ua rau nws tiv taus hnav thiab deformation, ua rau nws zoo tagnrho rau kev siv zog siab.
C71500 tsis xav tau kev kho cua sov rau kev txhim kho lub zog. Txawm li cas los xij, nws tuaj yeem raug muab tshem tawm kom txo kev ntxhov siab thiab txhim kho machinability. Thaum lub sij hawm annealing, lub alloy yog rhuab mus rau ib tug kub ntawm 620 thiab 760 degree, txias maj mam nyob rau hauv huab cua los yog dej, thiab ces tempered nyob rau hauv chav tsev kub.
C71500 tuaj yeem nkag tau yooj yim welded siv ntau txoj kev, suav nrog roj tungsten arc vuam thiab roj hlau arc vuam. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav qhov saum npoo thiab siv cov hlau uas tsim nyog los tiv thaiv porosity thiab tawg.
C71500 nthuav tawm zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv seawater thiab lwm yam dej qab zib ib puag ncig. Nws muaj kev tiv thaiv zoo rau crevice corrosion, kev nyuaj siab corrosion cracking, thiab pitting. Nws cov kev tiv thaiv corrosion ua rau nws tsim nyog rau kev siv dej hiav txwv, kev lag luam tshuaj lom neeg, thiab kev tshawb nrhiav roj thiab roj.
