Txhuas Bronze NES835 (UNS C72420)
UNS C72420 nruab nrab-muaj zog nag lossis daus hardened cupronickel alloy muab rau hauv qhov kub tau ua haujlwm. Nws muaj li ntawm 14.5% npib tsib xee thiab 4,5% manganese ntxiv los ntawm kev sib ntxiv ntawm txhuas thiab hlau, uas yuav raug kho los ntawm kev tswj hwm me me ntawm chromium.
Nyob rau hauv ntau qhov tseem ceeb marine siv, piv txwv li ntawm cov roj platform thiab naval nkoj, qhov yuav tsum tau ua rau kev pabcuam tam sim ntawd tom qab lub sijhawm tsis muaj peev xwm ua rau muaj qhov cuam tshuam los tiv thaiv thiab xeb tsis zoo ntawm cov khob khob; tab sis cov pa hauv nruab nrab muaj qhov tsis zoo ntawm qhov tsis tshua muaj lub zog. Kev sib xyaw ntawm lub zog tsim nyog nrog kev zoo corrosion thiab impingement kuj tau tiav nrog npib tsib xee txhuas bronze tab sis qib siab muaj zog tau tsuas yog tau ua tiav ntawm qhov them nyiaj ntawm qhov nro nrog cov txiaj ntsig txwv tsis kam mus poob siab.

NES 835 yog aluminium bronze uas muaj lub zog zoo ua ke nrog cov dej hiav txwv zoo thiab kev yaig tsis zoo yog li siv ntau hauv kev lag luam marine. Tsis tas li NES835 tau yog ib qho ntawm cov ntaub ntawv tsuas yog qhia xwm yeem tsis muaj kev cuam tshuam ntawm hydrogen embrittlement thiab tseem muaj kev ntxhov siab zoo corrosion tawg nrog kev sib ntxiv ntawm cov hlau hauv ammonia tab sis cov ntsiab lus hlau yuav tsum qis dua 1% thiab cov hlau yuav tsum tau ceev cia hauv kev daws teeb meem Cov.
