Hauv luv luv: Ni200 yog tus qauv, kev lag luam ntshiab npib tsib xee, thaum Ni201 yog nws qis-carbon, siab- kub- tshwj xeeb version. Qhov sib txawv tseem ceeb nyob rau hauv kev tswj cov ntsiab lus ntawm cov pa roj carbon monoxide, uas ncaj qha txiav txim siab lub siab txwv ntawm nws qhov kev ua haujlwm kub.
Ni200 thiab Ni201 yogcov khoom siv nickel ntshiablos ntawm tib qhov chaw. Qhov sib txawv ntawm cov ntsiab lus carbon ua rau Ni201 siab - cov khoom siv kub, thaum Ni200 yog tus nqi zoo tshaj rau cov nyiaj ntawm chav tsev kub. Tus yuam sij rau kev xaiv yog qhov kub thiab txias.
Kev sib piv ntawm cov khoom tseem ceeb (feem ntau qhov sib txawv):
Ob leeg yog kev lag luam -qib npib tsib xee ntshiab nrog purity Ntau dua lossis sib npaug li 99%. Qhov tseem ceeb sib txawv tsuas yog cov ntsiab lus carbon (C):
| Cov ntsiab lus | Ni200 (N02200) | N201 (N02201) | Kev npam |
|---|---|---|---|
| Ni | Ntau dua lossis sib npaug li 99.0% | Ntau dua lossis sib npaug li 99.0% | Cov yam ntxwv ntawm corrosion kuj, hluav taws xob conductivity, thiab thermal conductivity yog zoo ib yam. |
| C | Tsawg dua lossis sib npaug li 0.15% (High carbon) | Tsawg dua lossis sib npaug li 0.02% (Cov pa roj carbon tsawg heev) | Txiav txim siab kub stability |
| Fe | Tsawg dua lossis sib npaug li 0.40% | Tsawg dua lossis sib npaug li 0.40% | Cov ntsiab lus impurity |
| Manganese / Silicon / Tooj | Tsawg dua lossis sib npaug li 0.35% | Tsawg dua lossis sib npaug li 0.35% | Cov ntsiab lus impurity |
Qhov tseem ceeb ntawm kev ua haujlwm sib txawv
1. Chav ntsuas kub ua haujlwm (yuav luag tsis sib txawv)
Mechanical Properties: Tensile zog, yield zog, thiab elongation yog zoo tib yam.
Corrosion Resistance: Ua rau muaj zog alkalis, nruab nrab ntsev, txo cov kua qaub, thiab dej hiav txwv zoo ib yam nkaus.
Lub cev muaj zog: Ob leeg yog ferromagnetic; Qhov ceev, thermal conductivity, thiab hluav taws xob conductivity zoo ib yam.
2. Kev ua haujlwm kub siab (Kev txiav txim siab txawv)
Ni200: Siab Limit ntawm Ntev -Lub Sijhawm Ua Haujlwm Kub: Tsawg dua lossis sib npaug li 315℃(600℃F)
Kev pheej hmoo: Nrog ntev - siv lub sij hawm ntev tshaj 315 degree, carbon yuav precipitate graphite ntawm grain ciam teb → graphitization thiab embrittlement → ib tug ntse poob nyob rau hauv plasticity thiab toughness, ua rau nws nquag tawg.
Ni201: Lub Sij Hawm Ntev Ntev -Lub Sijhawm Ua Haujlwm Kub: Tsawg dua lossis sib npaug rau 677℃(1250℃F)
Qhov zoo: Cov ntsiab lus carbon tsawg heev tshem tawm qhov kev pheej hmoo ntawm graphitization; siab -kub yam ntxwv stability, muaj zog tiv thaiv creep thiab intergranular corrosion.
Tej kev siv
Ni200 (Economical)
Thaum ua haujlwm kub < 315℃, tsis muaj sijhawm ntev -lub sij hawm siab - kub:
Electronics & Hluav taws xob: roj teeb casings, electrodes, conductive leads
General Chemicals: Ambient kub cia tank, pipelines, marine hardware
Khoom noj khoom haus / Lub teeb kev lag luam: Cov tais diav, fasteners, hlau mesh
Ni201 (High -Kev Nyab Xeeb Kub)
Thaum kub> 315℃lossis siab -purity / corrosive ib puag ncig yuav tsum tau:
Chlor-alkali Kev Lag Luam: Siab- cov khoom siv dej kub kub
Petrochemicals: Hydrogenation reactors, siab - kub exchangers
Kev Lag Luam Nuclear: Siab - ua cov pa roj purity
Thaum tshav kub kub- ua pwm, siab - qhov kub thiab txias elastic Cheebtsam
