Qib kawm thiab tsom xam ntawm tsawg -} ecoy siab - lub zog txheem hlau

Cov qhab nia thiab kev faib tawm tsawg -} ally high cov ntsiab lus "thiab" muaj zog inelot los ntawm kev ntsuas tshuaj lom neeg thiab cov khoom siv txhua yam los ntawm cov khoom siv. Hauv qab no yog cov kev cai ntawm qib thiab cov qauv los ntawm cov qauv tseem ceeb:

I. Suav Txheem (GB / T 1591-2018)

Qib Teeb Meem

Q + Cov Ncauj Lub Zog Muaj Peev Xwm + Cov Qauv Zoo + Deoxidation Txoj Kev (Xaiv tau)

 

Q: Pinyin Pib "tawm los," sawv cev rau lub zog muaj zog.

Paib lub zog muaj zog: Chav nyob rau hauv MPA (piv txwv li, Q355 qhia tawm cov txiaj ntsig zoo dua lossis sib npaug rau 355 MPa).

Cov Qeb Zoo: Tso cai los ntawm kev cuam tshuam cov tawv rau hauv A, B, C, D, E (kev cuam tshuam kub txo qis dua, muaj ntau dua cov kev yuav tsum muaj):

Qib A: Tsis muaj qhov cuam tshuam xeem;

Qib B: {+20℃cuam tshuam xeem;

Qib C: 0℃cuam tshuam xeem;

Qeb D: -20℃cuam tshuam xeem;

Qib E: -40℃cuam tshuam xeem.

Deoxidation txoj kev: F (rimmed hlau), z (tua cov hlau), TZ (cov hlau tua neeg tshwj xeeb), feem ntau zam.

Cov qib

Teem nqi	Yield zog (mpa)	Alloy keeb cov yam ntxwv	Daim Ntawv Thov Kev Pab Cuam
Q345	Ntau dua los yog sib npaug rau 345 (yav tas los 16mn)	Mn - Raws (1.0% -1.6%), nrog SI, V, NB, ti	Txuas hniav, tsheb, cov hlab ntsha siab
Q355	Ntau dua los yog sib npaug rau 355 (hloov Q345)	Optimized alloy piv, txhim kho corrosion tsis kam	Cov Qauv Hlau, Cua Turbine Yees
Q420	Ntau dua los yog sib npaug rau 420	Ntxiv mo, CR rau ntxiv dag zog, nrog NB / V rau cov khoom siv qoob loo	Siab -} Rose Vaj tse, Machinery
Q690	Ntau dua los yog sib npaug rau 690	Quenched thiab tempered, nrog ni, cr, mo	Kev Siv Machinery, Khoom Siv Mining, Offshore Platforms
