Raws li lub npe qhia,naval tooj dagyog tooj liab alloy haum rau marine scenes. Nws cov khoom tseem ceeb yog tooj liab (Cu), zinc (Zn) thiab tin (Sn). Cov hlau no tseem hu ua tin tooj dag. Qhov sib ntxiv ntawm tin tuaj yeem cuam tshuam qhov dezincification ntawm tooj dag thiab txhim kho corrosion kuj.
Nyob rau hauv lub marine ib puag ncig, ib tug nyias thiab tuab tiv thaiv zaj duab xis yuav tsim nyob rau saum npoo ntawm tooj liab alloy, uas yog tsuas yog tsim los ntawm tooj liab thiab tin oxides thiab ib co complex ntsev. Cov txheej txheem tiv thaiv no tuaj yeem tiv thaiv cov dej hiav txwv los ntawm corroding sab hauv ntawm cov hlau thiab ua kom qeeb ntawm corrosion. Piv nrog cov tooj dag zoo tib yam, tus nqi corrosion ntawm naval tooj dag tuaj yeem raug txo ob peb zaug.
Common naval tooj liab alloys suav nrogc44300 ua(HSn70-1 / T45000), uas muaj cov hauv qab no:
Tooj liab (Cu): 69.0% - 71.0%
Zinc (Zn): Sib npaug
Tin (Sn): 0.8% - 1.3%
Arsenic (As): 0.03% - 0.06%
Lwm yam alloying ntsiab: ≤0.3%
Arsenic tuaj yeem inhibit dezincification corrosion thiab ntxiv txhim kho corrosion kuj ntawm alloy.C44300 muaj cov khoom siv zoo thiab siv los ua cov khoom siv hluav taws xob thiab cov kav dej uas tuaj yeem tiv nrog cov kua corrosive. Nws yog tshwj xeeb tshaj yog dav siv nyob rau hauv dej thermal fais fab nroj tsuag los ua high-strength, corrosion-resistant tshav kub exchanger condenser hlab. Cov kev tshawb fawb tsis ntev los no tau pom tias ntxiv cov lej ntawm boron, npib tsib xee thiab lwm yam khoom rau C44300 tuaj yeem txhim kho corrosion kuj zoo dua. C44300 muaj qhov ua rau muaj kev ntxhov siab corrosion tawg, thiab cov kav dej txias ua haujlwm yuav tsum raug rau kev ntxhov siab txo qis-kub annealing. C44300 yog nquag tawg thaum lub sij hawm kub nias, thiab cov ntsiab lus ntawm impurities yuav tsum nruj me ntsis tswj.
c46400 ua(HSn62-1/T46300) kuj yog ib tug naval tooj dag nrog cov ntsiab lus tooj liab. Nws cov khoom tseem ceeb yog raws li nram no:
Cov nqi kawm ntawv: 61-63%
Zn: 35.4-38.3%
Cov ntsiab lus: 0.7-1.1%
Fe: ≤0.1%
Pb: ≤0.1%
C46400 yog txias brittle thaum lub sij hawm ua hauj lwm txias thiab tsuas yog haum rau kub nias. Nws muaj kev ua haujlwm zoo thiab yooj yim rau welding thiab braze, tab sis muaj kev nyiam rau corrode thiab tawg (seasonal crack). C46400 tin tooj dag yog siv hauv kev lag luam shipbuilding los tsim cov khoom uas tuaj rau hauv dej hiav txwv, roj av, thiab lwm yam.
Vim qhov sib txawv me ntsis ntawm cov qauv, raws li Suav tooj dag sawb / tooj dag pas nrig /tooj liab phaj tsum, peb feem ntau siv HSn62-1 los hloov C46400 / C46200 / C4621. Cov ntsiab lus tooj liab ntawm C46200 yog siab dua me ntsis.
c48500 ua(QSn4-3) yog cov hlau lead-nkoj tooj dag. Cov ntsiab lus txhuas yog siab dua ob qib uas tau hais los saum toj no. Nws cov khoom tseem ceeb yog raws li nram no:
Tooj liab (Cu): 59.0% ~ 62.0%
· Lead (Pb): 1.3% ~ 2.2%
Hlau (Fe): ≤0.10%
Tin (Sn): 0.5% ~ 1.0%
· Zinc (Zn): Sib npaug
Phosphorus (P): 0.02% ~ 0.10%
Nws muaj qhov zoo elasticity, hnav tsis kam thiab tiv thaiv hlau nplaum. Nws yog qhov tsim nyog rau kev ua haujlwm siab hauv cov xeev txias thiab kub. Nws yog ib qho yooj yim rau weld thiab braze. Nws muaj zoo machinability thiab zoo corrosion kuj nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv. Nws yog feem ntau siv nyob rau hauv ntau yam elastic Cheebtsam, yeeb nkab fittings, chemical khoom, hnav-resistant qhov chaw thiab anti-magnetic qhov chaw.
