Nkag Siab Txog 8Cr13MoV Hlau

Txheej txheem cej luam

8Cr13MoV yog hlau tsis xeb Suav teb uas feem ntau piv rau hlau Nyiv Pooj AUS-8. Nws muaj qhov sib npaug ntawm qhov tawv, tiv taus xeb, thiab pheej yig. Nws siv dav hauv cov riam nruab nrab thiab pheej yig vim nws ua tau zoo thiab yooj yim rau kev ntse.

Cov Tshuaj Lom Zem

Cov qauv sib xyaw ua ke ntawm 8Cr13MoV hlau:

• Cov pa roj carbon (C): 0.75 - 0.85%

• Chromium (Cr): 13.0 – 14.5%

• Molybdenum (Mo): 0.10 – 0.30%

• Vanadium (V): 0.10 - 0.25%

• Manganese (Mn): ≤ 1.0%

• Silicon (Si): ≤ 1.0%

Cov Khoom Tseem Ceeb

• Qhov nyuaj: 57–59 HRC tom qab kev kho cua sov

• Kev Tiv Thaiv Hnav: Nruab Nrab

• Kev tawv ncauj: Zoo rau cov hlau tsis xeb

• Kev Tiv Thaiv Kev Xeb: Siab vim muaj cov chromium ntau dua

• Kev Khaws Cia Ntug: Nruab nrab, yooj yim dua rau kev ntse dua li cov hlau tawv dua

Cov Kev Siv Feem Ntau

• Cov riam nqa txhua hnub (EDC)

• riam chav ua noj

• Cov riam siv sab nraum zoov thiab cov riam siv tau

• Cov riam uas yooj yim rau kev siv nyiaj

D2 Hlau vs 8Cr13MoV Hlau: Kev Sib Piv Kom Paub Ntxiv

1. Kev Nyuaj thiab Kev Khaws Cia Ntug

• D2 HlauQhov nyuaj dua (txog li 62 HRC) txhais tau tias nws tuav tau ntug ntev dua thiab yuav tsum tau ntse tsawg dua. Txawm li cas los xij, nws nyuaj dua rau ntse thaum nws tsis ci.

• 8Cr13MoV Hlau: Qhov nyuaj me ntsis tab sis yooj yim dua rau kev ntse, ua rau nws yooj yim dua rau cov neeg siv yooj yim.

2. Hnav Tsis Taus

• D2 Hlau: Tiv taus kev hnav zoo heev vim muaj cov pa roj carbon thiab carbide ntau, zoo tagnrho rau kev txiav cov haujlwm hnyav.

• 8Cr13MoV Hlau: Zoo hnav tsis kam tab sis tsis sib npaug nrog D2, tsim nyog rau kev siv nruab nrab.

3. Kev Tiv Thaiv Kev Xeb

• D2 Hlau: Semi-stainless; tuaj yeem tiv taus xeb zoo dua li cov hlau carbon yooj yim tab sis tseem yooj yim rau cov xim av hauv cov chaw noo noo lossis ntsev yog tsis muaj kev saib xyuas zoo.

• 8Cr13MoV Hlau: Tag nrho stainless nrog cov chromium ntau dua, muab kev tiv thaiv xeb zoo dua hauv cov xwm txheej ntub dej.

4. Kev tawv

• D2 Hlau: Muaj zog nruab nrab; tuaj yeem tawg yog tias siv rau kev thawb lossis kev cuam tshuam hnyav.

• 8Cr13MoV Hlau: Zoo dua me ntsis, zam txim ntau dua thaum siv tsis zoo.

5. Yooj yim ntawm kev ntse

• D2 Hlau: Nyuaj dua rau kev ntse vim muaj kev tawv thiab kev hnav tsis kam; xav tau cov cuab yeej ntse pob zeb diamond lossis ceramic.

• 8Cr13MoV Hlau: Yooj yim dua rau kev ntse nrog cov cuab yeej ntse txheem, txawm tias nyob hauv thaj teb.

6. Tus nqi

• D2 HlauFeem ntau kim dua, siv rau hauv cov riam zoo tshaj plaws thiab cov riam qib tshaj lij.

• 8Cr13MoV Hlau: Pheej yig, ua rau nws nrov rau cov riam pheej yig nrog kev ua tau zoo.
