Txog 4130 Hlau (Cov Khoom, Lub Zog, thiab Kev Siv)

Khoom	Feem pua ​​(%)
Cov pa roj carbon (C)	0.28 – 0.33
Chromium (Cr)	0.80 – 1.10
Molybdenum (Mo)	0.15 – 0.25
Manganese (Mn)	0.40 – 0.60
Silicon (Si)	0.15 – 0.35
Sulfur (S)	≤ 0.040
Phosphorus (P)	≤ 0.035

Chromium ua rau kom muaj zog, lub zog tensile, thiab kev tiv thaiv corrosion, thaum molybdenum txhim kho kev tawv, kev tiv thaiv creep, thiab kev tawv.

Lub zog ntawm 4130 Hlau

Lub zog ntawm 4130 hlau nyob ntawm kev kho cua sov. Hauv qhov xwm txheej annealed, nws muaj lub zog nruab nrab tab sis kev siv tshuab siab. Hauv lub xeev quenched thiab tempered, nws ua tiav ntau dua tensile thiab cov txiaj ntsig muaj zog, ua rau nws tsim nyog rau cov khoom siv hauv qab hnyav.

Piv txwv li:

• Annealed MobLub Zog Tensile ~ 560 MPa, Lub Zog Tawm ~ 460 MPa

• Quenched & Tempered MobLub Zog Tensile ~ 1080 MPa, Lub Zog Tawm ~ 930 MPa

Qhov ntau yam kev ua tau zoo ntawm cov khoom siv kho tshuab no ua rau 4130 hlau muaj ntau yam siv tau thoob plaws ntau yam lag luam.

Kev vuam thiab kev siv tshuab

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 4130 hlau yog nws qhov kev vuam zoo. Nws tuaj yeem vuam siv TIG, MIG, lossis oxy-acetylene txoj kev, muab qhov ua ntej kom zoo (150 ° C - 300 ° C) ua tiav kom tsis txhob tawg. Kev txo qhov kev ntxhov siab tom qab vuam feem ntau yog siv rau cov khoom tseem ceeb.

Kev siv tshuab tau suav tias zoo thaum cov hlau nyob rau hauv qhov xwm txheej annealed. Kev kho cua sov 4130 yuav xav tau cov cuab yeej carbide thiab qeeb qeeb.
