30CrNi3MoV(675) steel phaj yog siab -lub zog alloy steel renowned rau nws tshwj xeeb ua ke ntawmyield zog (Ntau dua los yog sib npaug rau 675 MPa), tawv, thiabhardenability, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hauv kev thov kev lag luam. Lub npe "30CrNi3MoV" qhia txog nws cov tshuaj muaj pes tsawg leeg (0.30% C, 1.4-1.8% Cr, 2.75-3.25% Ni, 0.25-0.40% Mo, 0.15-0.30% V), thaum "(675)" feem ntau qhia txog nws qhov kev tawm dag zog tsawg kawg nkaus. Hauv qab no yog ib qho kev ntsuam xyuas dav dav ntawm nws cov kev qhia tshwj xeeb, kev tsim khoom, kev siv, thiab kev ua lag luam zoo:

1. Kev qhia tshwj xeeb

Tshuaj muaj pes tsawg leeg

Cov pa roj carbon (C): 0.27–0.33%
Muab hardenability thiab lub zog.

Chromium (Cr): 1.40–1.80%
Txhim kho corrosion kuj thiab hnav tsis kam.

Nickel (Ni): 2.75–3.25%
Txhim kho toughness, ductility, thiab qis -kev ua haujlwm kub.

Molybdenum (Molybdenum): 0.25–0.40%
Nce creep kuj thiab suppresses temper embrittlement.

Vanadium (V): 0.15–0.30%
Refines grain qauv kom txhim kho lub zog thiab qaug zog tiv thaiv.

Mechanical Properties

Yield Strength (σ₀.₂):Ntau dua lossis sib npaug li 675 MPa (rau phaj thickness Tsawg dua lossis sib npaug li 100 mm)
Ua kom cov qauv kev ruaj ntseg nyob rau hauv siab loads.

Tensile zog (σ_b):835-980 MPa
Resistant yas deformation nyob rau hauv huab mob.

Elongation (A₅):Ntau dua lossis sib npaug li 15%
Muab ductility rau kev sib sau thiab vuam.

Impact Zog (KV₂ ntawm -20 degree):Ntau dua lossis sib npaug li 50 J
Qhia tau zoo heev toughness nyob rau hauv qhov chaw txias.

Hardness:241-285 HB (tom qab quenching thiab tempering)
Balances hnav tsis kam thiab machinability.

Kev kho cua sov

Quenching:Roj-quenched ntawm 850-880℃kom ua tiav cov qauv martensitic.

Tempering:Ua ntawm 580-680℃los txhim kho lub zog - toughness balance.
Piv txwv:Lub 50 hli tuab phaj tempered ntawm 650℃ua tiav lub zog ntawm 720 MPa.
