C70600 belongs rau tooj liab-nickel alloy (dawb tooj liab) series, nws muaj pes tsawg leeg yog:
Tooj liab (cu): 65% -70
Nickel (NI): 9% -11%
Hlau (FE): 1.0% -1.8}% (txhawm rau txhim kho corrosion tsis kam)
Manganese (MN): Tsawg dua lossis sib npaug ntawm 1.0% (txhawm rau txhim kho kev ua haujlwm)
Lwm tus: Zinc (ZN), Tin (Sn), txhuas (pb) thiab lwm yam impurities tag nrho tsawg dua los yog sib luag rau 1. 0%.
Lub alloy tseem hu ua "90-10 tooj liab-nickel alloy" lossis bfe} tooj liab {{}}
Cov Khoom Siv Lub Cev
Ntws: 8 {{. 94 g / cm³, ze rau cov tooj liab ntshiab tab sis nrog cov khoom siv zoo dua tab sis muaj cov kws kho tshuab zoo dua.
Melting taw tes: {{1149-1171, haum rau qhov kub ib puag ncig .
Thermal Conductivity: 50 . 2 w / (MK) (ntawm 20), tuaj yeem ua kom tau txais qhov kev thov ua kom sov dissipation.
Coefficient of Thermal Expansion: 16.5×10-⁶/C (20-100), better than C71500 and other similar alloys.
Hluav taws xob conductivity: 7 {{.} / m (txog 10% IRS), haum rau cov hluav taws xob tsis zoo.
III {.} Cov Khoom Siv Neeg Kho Tshuab
Lub zog tensile:
Annealed State: 275-380 mpa
Mob txias ua haujlwm: Txog 650 MPa
Paib lub zog: {{{{140-250 mpa mpa (anealed xeev), nce mus rau 600 mpa tom qab ua haujlwm txias.
Elongation: annealed lub xeev ntau dua los yog sib npaug ntawm 28% (thaum sauv thickness ntau dua los yog sib npaug rau 0.3 hli)
Hardness:
Brinell Hardness (HB): {110-1405
Rockwell Hardness (HRB): 50-705
Creep resistance: 500 nyob rau hauv tus nqi nkag siab tsawg dua los yog sib npaug rau 1 {{2} {{2} {{2} kub siab yog qhov zoo tshaj .
Corrosion Kuj
Dej hiav txwv corrosion:
Corrosion Txhua Xyoo<0.005 mm, suitable for seawater desalination pipelines, ship condensers and so on.
Kuj mus rau chloride ion pitting yog 3 zaug ntawm dog dig tooj liab .
Resistant rau tshuaj media:
Tiv taus p 3-11 kua qaub thiab alkali daws .
Tsis muaj kev ntxhov siab corrosion zoo li hauv cov sulphur-muaj thiab ammonia ib puag ncig .
Kev kub-kub oxidation kuj: oxidation tus nqi hauv qab 800 tsawg dua lossis sib npaug ntawm 0 {{}}} 1 mm / xyoo.
V . kev thiab kev kho cua sov
Txias ua haujlwm: 80% ntawm qhov siab tshaj plaws tso cai deformation, yuav tsum tau Anneal hauv theem kom tsis txhob tawg tawm.
Txheej Txheem Annealing:
Kub 780-810}} kom tshem tawm sab hauv kev ntxhov siab thiab rov qab muaj zog {}}
Ceev ceev txias yuav ua rau saum npoo oxidation .
Kev Ua Haujlwm Vuam: Txhawb Vuam, Mig vuam, tsim nyog tus nqi ntau dua los yog sib luag rau 95%.
Kev kho deg: electroplating, tshuaj lom neeg plating lossis txau los tiv thaiv cov txheej txheej corrosion yog muaj {}}
