Tus qauvEN 10025(European txheem rau kub-rolled txheej txheem hlau) siv cov cim tshwj xeeb thiab cov chaw ua haujlwm, tshuaj lom neeg, thiab cov muaj tshuaj lom neeg. Hauv qab no yog kev tawg ntawm cov cim thiab lawv lub ntsiab lus:

Cov qauv dav dav ntawm cov qauv hlau qib hauv EN 10025

Ib tus qauv steel nyob rau hauv EN 10025 ua raws cov qauv no:
S \/ E + [XEEM lub zog] + [Zoo \/ Kev Cuam Tshuam] + [Cov Kev Tshwj Xeeb]

1. Prefix Cov Tsiaj Ntawv

S: QhiaTxheej txheem steel(siv rau cov ntawv thov dav dav).

E: QhiaEngineering Hlau(siv rau cov tshuab kho tshuab, piv txwv li, cov ntaub qhwv, zog).

2. Yield zog (hauv MPA)

Ib tug zauv tseem ceeb sawv cev rauYam tsawg kawg nkaus xwb Zog(Thaum muaj 16 lub hli tuab) hauv megapescals (mpa) .examples:

S235: Tawm lub zog loj dua los yog sib npaug rau 235 MPa.

S355: Tawm lub zog loj dua los yog sib npaug rau 355 MPa.

3. Zoo thiab Kev Cuam Tshuam Cov Cim

Cov ntawv txhais tau tiasQhov Yuav Tsum Tau(Charpy V-nthuav tawm kev sim) thiab qib zoo:

 

JR(lossisJ2G3Hauv cov qauv qub):

Cuam tshuam xeem ntawm+20 degree(Yam tsawg kawg nkaus Zog: 27 J, cov qauv ntev).

J0:

Cuam tshuam xeem ntawm0 degree(Yam tsawg kawg nkaus Zog: 27 J).

J2:

Cuam tshuam xeem ntawm-20 degree(Yam tsawg kawg nkaus Zog: 27 J).

K2:

Cuam tshuam xeem ntawm-20 degreenrogYuav Tsum Muaj Zog Xav Tau(tsawg kawg 40 j).

N:

Qhia tauzoo li caslossis cov steelsized cov hlau (txhim kho cov khoom siv mechaychanical).

M:

Qhia tauThermo-Mech RolledHlau (tsis muaj kev xav tau rau kev kho cua sov-rolling sov).

Ml:

Thermo-Mech Rolled steel nrogTxhim Kho Cov Khoom Tsawg-Qhov Kub Kub.

4. Cov kev cai tshwj xeeb (yeem)

W: Huab cua tiv thaiv steel (piv txwv li, s355w).

H: Hollow cov ntu (piv txwv li, s355h).

Z: Z-Kev Taw Qhia Cov Khoom (Tsis kam mus rau Lamellar kua muag, piv txwv li, S355555).

Piv txwv qib qib qis dua

S355J2:

S: Cov qauv hlau qauv.

355: Yam tsawg kawg cov paib lub zog 355 MPa.

J2: Cuam tshuam kev xeem ntawm -20 degree (27 j).

S275jr:

S: Cov qauv hlau qauv.

275: Yam tsawg kawg nkaus paib zog 275 MPa.

JR: Cuam tshuam kev xeem ntawm +20 degree (27 j).
