Feem ntau tooj liab alloys corrode nyob rau hauv dej hiav txwv. Ib txhia kav ob peb xyoos. Lwm tus ua tsis tiav hauv lub hlis.C70600 nws txawv vim nws chemistry. Cov npib tsib xee thiab hlau ua haujlwm ua ke los tsim ib txheej nyias, tiv thaiv ntawm lub raj nplaim. Thaum cov txheej txheem tsim (feem ntau nyob rau hauv hnub ntawm dej hiav txwv raug), lub raj raug tiv thaiv. Lub txheej nws tus kheej kho yog khawb. Tsis muaj lwm yam tooj liab alloy ua qhov no thiab. Tias yog vim li cas engineers qhia C70600 rau cov dej hiav txwv tseem ceeb, tsis yog pheej yig dua.
Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm C70600 rau ASTM B111?
C70600 yuav tsum muaj 9.0-11.0% nickel, 1.0-1.8% hlau, thiab tsis pub ntau tshaj 1.0% manganese. Copper ua rau tus so, nrog kev txwv nruj rau cov hlau lead, zinc, carbon, thiab phosphorus.

FAQ
Q1: Dab tsi yog qhov tsawg kawg nkaus nickel cov ntsiab lus rau lub raj hu ua C70600?
9.0% yog qhov tsawg kawg nkaus rau ASTM B111. Hauv qab 9.0%, nws tsis yog C70600.Qee tus neeg muag khoom yuav sim muag cov khoom siv nrog 8.5% npib tsib xee li "C70600 hom". Tsis lees paub. Nickel yog dab tsi muab C70600 nws corrosion kuj. Them rau tag nrho spec.
Q2: Kuv puas tuaj yeem kuaj cov chemistry ntawm C70600 raj kuv tus kheej?
Tsis yog tsis muaj cov cuab yeej lab. Tab sis koj tuaj yeem ntiav ib lub chaw kuaj dawb.Xa 50mm qauv mus rau ib lub chaw kuaj mob uas ua OES spectrometry ib ASTM E1473. Tus nqi yog $100-200. Cov txiaj ntsig hauv 3-5 hnub. Test rau Ni, Fe, Mn, Pb, Zn. Yog tias cov txiaj ntsig tawm ntawm qhov tshwj xeeb, tsis lees txais cov batch.
Q3: Puas yog C70600 tib yam li CuNi10Fe1Mn?
Yog lawm, cov lej qhia rau koj: CuNi 10=10% npib tsib xee. Fe1=1% hlau. Mn=manganese.CuNi10Fe1Mn yog European (EN) tsim. C70600 yog US (UNS) xaiv. Chemistry ranges yog sib npaug. Yog tias koj xa tawm mus rau Tebchaws Europe, siv ob lub npe ntawm koj PO.
Q4: Lub raj C70600 ntev npaum li cas nyob rau hauv lub seawater txias cua sov exchanger?
20-30 xyoo yog qhov zoo rau kev tsim qauv zoo.Cov yam ntxwv uas txo lub neej: tshaj tawm tshaj 2.5 m / s, kub siab tshaj 60 degree, xuab zeb los yog khib nyiab hauv dej, sulfide kuab paug. Hauv dej hiav txwv huv ntawm 1.5-2.0 m / s thiab 30-40 degree, 30 xyoo yog qhov tseeb.
Q5: Kuv puas tuaj yeem txuas C70600 rau carbon steel?
Yog lawm, tab sis siv ERCuNi muab tub lim hlau thiab cia siab tias galvanic corrosion yog qhov sib koom ua ke rau hauv dej hiav txwv.Rau cov pob qij txha saum dej, vuam yog zoo. Rau kev pabcuam hauv qab dej lossis ntub dej, cais ob lub hlau nrog ib daim spool ntawm C70600 lossis siv lub flange coated.
Q6: Puas yog C70600 raug nqi ntau dua 316L stainless hlau?
Yog lawm, C70600 feem ntau yog 20-40% kim dua 316L ntawm ib-kg.Tab sis nyob rau hauv dej hiav txwv, 316L pits thiab tsis. C70600 kav 5-10x ntev. Tus nqi ntawm lub neej ntawm C70600 yog qis dua txawm tias tus nqi nce siab dua.
Q7: Dab tsi yog qhov siab tshaj plaws khiav ceev rau C70600 raj hauv dej hiav txwv?
2.5 m / s yog qhov siab tshaj plaws uas tau pom zoo rau kev pabcuam txuas ntxiv . 3.0 m / s tau txais kev pabcuam cuam tshuam.Tshaj 3.0 m / s, impingement corrosion pib ntawm tube inlets. Yog tias koj lub kaw lus khiav ntawm 3.5-4.0 m / s, hloov mus rau C71500.
Q8: C70600 puas tuaj yeem siv rau cov dej haus hauv nkoj?
Yog lawm, C70600 tau tso cai rau cov dej siv tau los ntawm ntau lub nkoj.Cov tooj liab ions tso tawm yog nyob rau hauv kev txwv tsis pub dhau. Txawm li cas los xij, qee tus neeg saib xyuas dej xav tau kev sim kom paub meej tias qib nyob qis dua hauv cheeb tsam txwv. Rau lub sijhawm ntev cia (dej tsis tu ncua), yaug dej ua ntej haus.
Q9: Yuav ua li cas kuv thiaj li nyeem cov chemistry seem ntawm Mill Test Report?
Saib rau ntu "kev txheeb xyuas cua sov". Nws yuav sau txhua lub ntsiab lus thiab cov nqi ntsuas.Kos Ni ntawm 9.0-11.0%. Xyuas Fe ntawm 1.0-1.8%. Kuaj Pb qis dua 0.02%. Kuaj Zn hauv qab 0.5%. Yog tias ib qho ntawm cov no tsis muaj ntau, tsis lees txais cov khoom.
Q10: Puas yog C70600 sib nqus?
Tsis yog, C70600 tsis yog hlau nplaum.Nws tsuas muaj 9-11% npib tsib xee, zoo hauv qab qib (ib puag ncig 30%) qhov twg tooj liab nickel ua hlau nplaum. Qhov no yog qhov tseem ceeb rau cov ntawv thov nyob ze ntawm lub compass lossis cov khoom siv hluav taws xob nkag siab.
Q11: Lub thermal conductivity ntawm C70600 yog dab tsi?
45 W / m·K ntawm 20 degree.Qhov no yog kwv yees li 12% ntawm cov tooj liab ntshiab (385 W / m·K) tab sis 3 zaug siab dua 316L stainless hlau (15 W / m·K). Rau kev tsim hluav taws xob sib txawv, koj xav tau thaj chaw ntau dua li cov tooj liab ntshiab tab sis tsawg dua stainless hlau.
Q12: Puas yog ASTM B111 tso cai rau welded C70600 raj lossis tsuas yog seamless?
ASTM B111 npog ob leeg seamless thiab welded raj. Txawm li cas los xij, seamless yog nyob deb ntawm feem ntau rau C70600.Welded C70600 raj tsis tshua muaj thiab feem ntau xav tau kev pom zoo ntawm tus neeg yuav khoom thiab zeb. Yog tias koj tau txais welded raj yam tsis tau thov, tsis lees txais nws.
