Kufotokozera
Monel 400 (UNS N04400/2.4360) ndi aloyi ya nickel-copper yokhala ndi mphamvu zambiri komanso yolimba kwambiri ku zinthu zosiyanasiyana kuphatikizapo madzi a m'nyanja, hydrofluoric ndi sulfuric acids, ndi alkali.
Monel 400 yokhala ndi mkuwa pafupifupi 30-33% mu nickel matrix ili ndi makhalidwe ambiri ofanana ndi nickel yoyera yogulitsa, pomwe ikukula kuposa ina yambiri. Kuwonjezera chitsulo pang'ono kumathandizira kwambiri kukana kuphulika kwa cavitation ndi kukokoloka kwa condenser tube. Ntchito zazikulu za Monel 400 zimakhala ndi liwiro lalikulu la kuyenda ndi kukokoloka monga momwe zilili mu propeller shafts, propellers, pump-impeller blades, casings, condenser tubes, ndi heat exchanger tubes. Kuchuluka kwa dzimbiri m'madzi a m'nyanja oyenda nthawi zambiri kumakhala kochepera 0.025 mm pachaka. Alloy imatha kulowa m'madzi a m'nyanja osakhazikika, komabe, kuchuluka kwa kuukira kumakhala kochepa kwambiri kuposa mu alloy yoyera yogulitsa 200. Chifukwa cha kuchuluka kwa nickel (pafupifupi 65%), alloy nthawi zambiri imakhala yotetezeka ku chloride stress corruption cracking. Kukana kwa dzimbiri kwa Monel 400 mu nonooxidant mineral acids kuli bwino poyerekeza ndi nickel. Komabe, ili ndi vuto lomweli losonyeza kukana dzimbiri kosakwanira ku zinthu zowononga monga ferric chloride, cupric chloride, wet chlorine, chromic acid, sulfur dioxide, kapena ammonia. Mu yankho la hydrochloric ndi sulfuric acid losagwiritsidwa ntchito, alloy imakhala ndi kukana kothandiza mpaka 15% kutentha kwa chipinda ndi mpaka 2% kutentha kwakukulu, kosapitirira 50°C. Chifukwa cha khalidweli, Monel 400 yopangidwa ndi NiWire imagwiritsidwanso ntchito m'njira zomwe chlorinated solvents ingapangitse hydrochloric acid chifukwa cha hydrolysis, zomwe zingayambitse kulephera kwa chitsulo chosapanga dzimbiri.
Monel 400 ili ndi mphamvu yolimbana ndi dzimbiri pa kutentha kozungulira mpaka kuchuluka konse kwa HF popanda mpweya. Mayankho opumira mpweya komanso kutentha kwambiri kumawonjezera kuchuluka kwa dzimbiri. Chitsulochi chimatha kusweka mosavuta ndi dzimbiri mu nthunzi yonyowa ya hydrofluoric kapena hydrofluorosilic acid. Izi zitha kuchepetsedwa mwa kuchepa kwa mpweya m'malo kapena kuchepetsa kupsinjika kwa chinthu chomwe chikukambidwa.
Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri ndi monga zida za valavu ndi pampu, ma propeller shaft, zida za m'madzi ndi zomangira, zida zamagetsi, zida zopangira mankhwala, matanki a petulo ndi madzi abwino, zida zopangira mafuta, zotenthetsera madzi a boiler ndi zina zosinthira kutentha.
