Dab tsi yog qhov txawv ntawm npib tsib xee N02200 (Ni200) thiab N02201 (Ni201)?
Cov kab lus hauv qab no piav qhia yuav ua li cas paub qhov txawv ntawm cov nickel alloy ntshiab N02200 (Ni200) thiab N02201 (Ni201):
Ua ntej, muab qee qhov kev taw qhia txog N02200 (Ni200) thiab N02201 (Ni201):
N02200/Ni200 ntshiab npib tsib xee yog cov khoom siv ntau yam thiab tseem ceeb heev ntawm cov hlau. Nws yog dav siv hauv kev lag luam vim nws lub zog zoo thiab cov yas toughness. Ntxiv nrog rau kev tsim cov khoom muaj txiaj ntsig nrog lwm cov hlau, cov nickel ntshiab muaj cov khoom zoo. Siv ib leeg ua cov khoom siv tiv thaiv corrosion-resistant thiab cov ntaub ntawv ua haujlwm. Qhov tseeb, cov nickel ntshiab siv los ua cov khoom siv corrosion-resistant yog cov nickel-carbon alloy uas muaj cov pa roj carbon.
N02201 / No2201 ntshiab npib tsib xee yog cov khoom siv hlau ntau thiab tseem ceeb heev. Nws yog dav siv hauv kev lag luam vim nws lub zog zoo thiab cov yas toughness. Ntxiv nrog rau kev tsim cov khoom muaj txiaj ntsig nrog lwm cov hlau, cov npib tsib xee ntshiab muaj cov khoom zoo Siv ib leeg ua cov khoom siv tiv thaiv corrosion-resistant thiab cov khoom siv. Qhov tseeb, cov nickel ntshiab siv los ua cov khoom siv corrosion-resistant yog cov nickel-carbon alloy uas muaj cov pa roj carbon.
Hauv cov ntsiab lus, N02200 (Ni200) thiab N02201 (Ni201) tau hais los saum toj no yog ob qho tib si npib tsib xee alloys ntshiab, uas kuj muaj cov hlau nplaum carbon, ua rau lawv hu ua nickel-carbon alloys.
Ib txoj hauv kev yooj yim thiab meej kom paub qhov txawv ntawm cov khoom siv hlau yog los sib piv cov tshuaj hlau cov khoom:
N02200 / Ni200 tshuaj hlau muaj pes tsawg leeg (%):
Carbon C: Tsawg dua lossis sib npaug rau 0.15,
Silicon Si: Tsawg dua lossis sib npaug rau 0.35,
Manganese Mn: Tsawg dua lossis sib npaug rau 0.35,
Sulfur S: Tsawg dua lossis sib npaug rau 0.01,
Nickel: 99 hli,
Cobalt Co: 99,
Hlau Fe: Tsawg dua lossis sib npaug rau 0.40,
Copper Cu: Tsawg dua lossis sib npaug rau 0.25.
N02201 (Ni201) chemical hlau muaj pes tsawg leeg (%):
Carbon C: Tsawg dua lossis sib npaug rau 0.02,
Silicon Si: Tsawg dua lossis sib npaug rau 0.35,
Manganese Mn: Tsawg dua lossis sib npaug rau 0.35,
Sulfur S: Tsawg dua lossis sib npaug rau 0.01,
Nickel: 99 hli,
Cobalt Co: 99,
Hlau Fe: Tsawg dua lossis sib npaug rau 0.40,
Copper Cu: Tsawg dua lossis sib npaug rau 0.25.
Nyob rau hauv txhua tus qauv, lawv cov npe sib txawv, tab sis lawv cov khoom siv cov yam ntxwv yog kwv yees li qub:
N02200 / No2200 cov qib sib xws:
Hom Lub Npe: N8,
American label: Nickel 200, No 2200,
German hom naj npawb: 2.4066, Nickel99.2
N02201 / No2201 cov qib sib xws:
Lub Npe Lub Npe: N6,
American label: Nickel 201, No 2201,
German hom naj npawb: 2.4068, Nickel99
Ib puag ncig uas siv cov ntaub ntawv hlau yuav ua rau corrosion, hnav thiab tawg ntawm cov khoom, yog li kev xaiv cov khoom yuav tsum tau muab qhov tseem ceeb.
Hais txog cov khoom tiv thaiv corrosion ntawm N02200 (Ni200) thiab N02201 (Ni201) cov ntaub ntawv yws txog hauv kab lus no, cov hauv qab no yog cov lus qhia luv luv:
Corrosion kuj ntawm N02200 (Ni200): Nws corrodes qeeb heev nyob rau hauv cov huab cua. Nws muaj corrosion kuj zoo nyob rau hauv seawater thiab HCl nyob rau hauv ntau yam hydrochloric acids. Txawm li cas los xij, nws yuav tsum tau siv nrog ceev faj nyob rau hauv HIC acids nrog cov nqi ntws siab. Nws tsis muaj nyob rau hauv H3PO4 thiab HNO3. , H2SO4 tsuas yog siv tau rau hauv H2SO4 yam tsis muaj cua, muaj qhov zoo corrosion kuj nyob rau hauv high temperature anhydrous HF, muaj corrosion kuj zoo nyob rau hauv kub chlorine thiab HCl, muaj zoo corrosion kuj nyob rau hauv chlorine thiab fluorine roj corrosion kuj.
N02201/No2201 Corrosion Resistance: Nws corrodes qeeb heev hauv huab cua. HCl muaj corrosion kuj zoo nyob rau hauv seawater thiab ntau yam hydrochloric acids. Txawm li cas los xij, nws yuav tsum tau siv nrog ceev faj nyob rau hauv HIC acids nrog cov nqi ntws siab. Nws tsis tuaj yeem siv hauv H3PO4 thiab HNO3. H2SO4 tsuas yog siv tau rau hauv airless H2SO4. Nws muaj corrosion kuj zoo nyob rau hauv high-temperature anhydrous HF, muaj corrosion kuj zoo nyob rau hauv high-temperature chlorine thiab HCl, thiab muaj corrosion kuj zoo nyob rau hauv chlorine thiab fluorine gases. Corrosion kuj, thiab nws cov vuam tsis kam mus rau intergranular corrosion yuav zoo dua (tsuas yog vim nws txo cov ntsiab lus carbon).
