ASTM B111 Tooj liab raj PDF

C44300 Tin Brass (tsis yog C44300)Yog lub tooj liab - zinc alloy nrog zoo tshaj plaws corrosion, zwm rau tus kws lij choj tooj dag series raws li Asmeskas Astm tus qauv. Vim nws cov kev ua tau ruaj khov hauv dej hiav txwv, dej tsis tau, ib puag ncig, nws yog dav siv hauv kev hloov pauv cua sov, cov hws, thiab cov raj xa nkoj. Feem ntau hauv daim ntawv ntawm cov kav dej, cov khoom no sib txuas nrog cov khoom siv tau zoo tshaj plaws nrog cov khoom tseem ceeb, ua rau cov khoom tseem ceeb hauv cov marine engineering thiab tshuaj siv tshuaj.

C44300 yog ua raws tus tooj liab (Cu) Matrix (70.0% -73.0%), nrog Zinc (ZN) raws li kev ua thawj coj (seem tseem tshuav). Tin (Sn) Ranges los ntawm 0.9% -1.2% thiab arsenic (li) li 0.02% -0.10%. Qhov kev sib ntxiv ntawm kev kho tau yooj yim txhim kho cov alloy cov corrosion tsis kam, tshwj xeeb yog inhibiting duzincification corrosion. Cov nyiaj tau los ua cov qoob loo ntxiv txuas ntxiv cov qoob loo ciam chaw ruaj khov, qeeb txoj kev corrosion. Tsis tas li ntawd, cov qib tsis huv xws li cov hmoov txhuas (PB) thiab hlau (FE) yog txwv tsis pub tsawg (feem ntau pb tsawg dua lossis sib npaug nrog 0.07%) kom ntseeg tau cov khoom siv huv.

Cov Khoom Siv Lub Cev
Qhov ceev faj: kwv yees li 8.53 g / me ntsis siab dua txawv txawv tab sis tseem sib dua dua li feem ntau corrosion {1} {tsis tshua muaj hlau. Hluav Taws Xob / Thermal conductivity: Kev ua hluav taws xob raug hluav taws xob yog 28% I SICS, thiab thermal conductivity yog kwv yees li cov kev siv hluav taws xob uas yuav tsum tau ua ob qho hluav taws xob kom muaj kev cuam tshuam nrog ob qho kub dissipation.
Corrosion Kuj: Zoo heev corrosion nyob rau hauv seawater, thiab chlorine {}}}}}}}} (dhau ntawm ASTM B858 DEZINCICATION Test). Lub surter kub txwv rau ntev- kev siv siv yog kwv yees li 200 degree.

Cov Khoom Siv Neeg Kho Tshuab
Lub zog tensile: kwv yees li 330-380 MPa hauv Annealed State, ncav 500-600 MPa tom qab ua haujlwm txias.
Kev Txiaj Ntsig: Annealed Elongation yog ntau dua los yog sib luag rau 40%, tswj 15%}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
Hardness: Lub hardness yog HB 60-100, tau kho tau los ntawm kev ua haujlwm txias.

Qhov Zoo
Corrosion Kuj:Tin thiab arsenic synergistically ua cov yeeb yaj kiab dense oxide, ua tau zoo tiv thaiv dej hiav txwv corrosion thiab kev nyuaj siab corrosion tawg.Thermal efficiency:Siab thermal conductivity ua ke nrog high-} dej tsis kam ua rau nws haum rau kev sib pauv cua sov.
Muaj peev xwm:Cov yeeb nkab tuaj yeem ua tiav los ntawm cov txheej txheem xws li cua txias txias thiab tawg, thiab nws weldability yog zoo dua rau cov hmoov txhuas (tig vuam).

Cov Kev Siv Raug Nyob Ntawm Astm B111 C44400 Hom K Tooj Liab Tubing:
Marine Engineering:Nkoj Condenser Tubes, Desalination cog ntoo, thiab seamas Valve Lub Tsev Haujlwm.
Zog thiab Tshuaj lom neeg:Lub hwj chim cog condenser leeg, refinery hluav taws kub cov pa roj, thiab lub zog nuclear cog txias tshuab.
Tsev HVAC:Cov cua txias thiab tub yees cov raj faib khoom, dej kub faib dej rau ib puag ncig muaj chlorine.

Machining thiab kho cov ntsiab lus tseem ceeb rau ASTM B111 C44400 Tooj Yeeb Rau AC:
Txoj kev tsim:Cov kub dov kub yog pom zoo kom tswj tau ntawm 700-800 degree; Thaum ua haujlwm txias, deformation yuav tsum tau tswj (feem ntau tsawg dua lossis sib npaug nrog 50%) kom tsis txhob tawg.
Annealing:Intermediate annealing kub yog 650-750 degree. Ib qho chaw tiv thaiv (xws li nitrogen) tuaj yeem tiv thaiv cov oxidation. Vuam thiabKoom Tes Nrog:Inert roj av tiv thaiv vuam yog qhov nyiam kom tsis txhob muaj kev phom sij loj los ntawm kev kub siab. Nyiaj -} Raws lossis phosphor - tooj liab brazing cov chaw ua tub rog tau pom zoo rau Brazing.
Nto Kho:Acid pickling (sib xyaw ntawm nitric acid thiab sulfuric acid) tuaj yeem siv los tshem tawm cov txheej oxide, lossis Tin Plating tuaj yeem siv los txhim kho corrosion tsis kam.

C44300 Tin Brass tubing, raws li ib tug "tiv thaiv corrosionor," tau dhau los ua cov khoom siv tsis tau hauv cov tubrog nkoj thiab kev lag luam zog. Nws cov nyhuv dezincification, tiav los ntawm cov nyhuv sinings ntawm tin thiab arsenic, tseem yog ib qho kev ua piv txwv ntawm tooj dag corrosion- tsis kam tsim. Txawm li cas los xij, kev sib tw ib puag ncig ib puag ncig thiab kev sib tw los ntawm alloys tshiab yog tsav tsheb rau hauv qis {} {{5} {{5} {{5} - Cov ntaub ntawv ua tau zoo. Nyob rau hauv lub neej yav tom ntej, los ntawm alter hloov chaw (xws li bismuth thiab pleev xim hloov tshuab) lossis cov tshuaj pleev ib ce hloov kho hauv kev ua kom ruaj khov nyob rau hauv kev ruaj khov thiab nthuav kev ua haujlwm.
