Monel K-500
Tsim los ua UNS N05500 lossis DIN W.Nr. 2.4375, Monel K-500 (tseem hu ua "Alloy K-500") yog cov nag lossis daus-tawv tawv nickel-tooj liab alloy uas sib txuas cov kev tiv thaiv corrosion ntawmMonel 400(Alloy 400) nrog ntau zog thiab hardness. Nws kuj muaj tsawg permeability thiab yog nonmagnetic rau hauv qab -100 ° C [-150 ° F]. Cov khoom muaj zog ntxiv yog tau los ntawm kev ntxiv txhuas thiab titanium rau cov npib tsib xee-tooj liab puag, thiab los ntawm cua sov nyob rau hauv kev tswj xyuas kom cov submicroscopic hais ntawm Ni3 (Ti, Al) yog precipitated thoob plaws hauv matrix. Monel K-500 feem ntau yog siv rau cov twj tso kua mis, cov cuab yeej roj zoo thiab cov cuab yeej, cov kws kho mob cov hniav thiab scrapers, springs, valve trims, fasteners, thiab marine propeller shafts.

3. Cov ntaub ntawv khoom, Weldability, Workability & Heat Treatment
Monel K-500 tuaj yeem muab tso rau hauv daim ntawv phaj, ntawv, sawb, bar, pas nrig, hlau, forgings, yeeb nkab & raj, fittings thiab fasteners raws li cov qauv txheeb ze xws li ASTM B865, BS3072NA18, BS3073NA18, DIN 17750, ISO 6208, DIN 17752, ISO 9725, DIN 17751, thiab DIN 17754, thiab lwm yam. Cov txheej txheem vuam tsis tu ncua rau Monel K-500 yog roj tungsten arc vuam (GTAW) nrog Monel muab tub lim hlau 60. Nws tuaj yeem ua tau yooj yim kub tsim los yog txias tsim. Qhov siab tshaj plaws kub ua haujlwm kub yog 2100 ° F thaum lub caij txias tuaj yeem ua tiav ntawm cov ntaub ntawv annealed. Kev kho cua sov tsis tu ncua rau Monel K-500 cov khoom feem ntau suav nrog ob qho tib si annealing (xws li kev daws annealing lossis txheej txheem annealing) thiab cov txheej txheem hnub nyoog hardening.
