C44300 Admiralty tooj dag
C44300 yog tooj liab-zinc-tin ternary-ib-theem tooj dag nrog cov qib me me ntawm arsenic, uas tuaj yeem cuam tshuam dezincification corrosion thiab txhim kho cov alloy qhov corrosion kuj. C44300 yog ib hom tin-plated tooj dag. Tooj, zinc, thiab tin yog cov khoom tseem ceeb ntawm cov hlau. Nws yog qhov zoo-paub rau nws zoo machinability, siab zog, thiab exceptional corrosion kuj. C44300 muaj cov cuab yeej zoo thiab siv los tsim cov khoom siv hluav taws xob thiab cov kav dej uas muaj kev sib cuag nrog cov kua corrosive. Nws yog tshwj xeeb yog siv nyob rau hauv dej thermal fais fab nroj tsuag rau fabrication ntawm high-zog, corrosion-resistant tshav kub exchanger condenser hlab.
Tin tooj dag, feem ntau hu ua admiralty tooj dag, yog corrosion-resistant nyob rau hauv ob qho tib si tshiab thiab ntsev. General admiralty tooj dag muaj 1 feem pua tin; tin ntau dhau txo cov hlau ductility. Admiralty tooj dag tau muab faib ua ob hom raws li nws cov ntsiab lus tin: admiralty tooj dag thiab (ntxiv rau) admiralty tooj dag. -single-phase admiralty tooj dag, xws li 70Cu-29Zn-1Sn, muaj cov khoom siv kho tshuab siab, nrog lub xeev mos tensile zog ntawm 350 MPa, elongation ntawm 60 feem pua, kev ua haujlwm txias txias, thiab muaj peev xwm tiv taus kub dov thiab kub extrusion tab sis tsis kub dabtsi yog khoov. Punching thiab kub forging yog feem ntau ua haujlwm nyob rau hauv kev tsim cov high-strength, corrosion-resistant condenser kav rau nkoj thiab thermal fais fab nroj tsuag. Vim tias cov hlau no ua rau muaj kev ntxhov siab corrosion tawg, cov kav dej txias ua haujlwm yuav tsum tau muab tshem tawm ntawm qhov kub thiab txias kom tshem tawm qhov nro. (ntxiv ) Admiralty tooj dag, xws li 62Cu-37Zn-1Sn, muaj cov khoom siv zoo, nrog lub zog tensile ntawm 380 MPa thiab elongation ntawm 40 feem pua. Nws yog ib qho yooj yim los txiav thiab vuam, thiab nws yuav ua tiav nyob rau hauv txias thiab kub siab. Zoo heev corrosion kuj nyob rau hauv seawater ua rau nws haum rau nkoj qhov chaw thiab qhov chaw nyob rau hauv kev sib cuag nrog seawater, roj av, thiab lwm yam.
