Ntawm no yog cov ncauj lus kom ntxaws saib ntawmHigh-Zoo Tsawg-Alloy High-zog Carbon Standes \/ Quaj (Q235B, Q345A) nrog ib qho tuab ntawm 16 hli, npog lawv cov specifications, khoom, thiab kev siv:

1. Cov qib thiab cov qauv

Q235B

Lub hom phiaj: Suav GB \/ T 700 (Carbon Qauv Hlau).

Kev sib faib: Cov hlau roj qis (hlau me), tsis nruj me ntsis "qib qis" tab sis dav siv rau cov hom phiaj dav dav.

Cov Nta Tseem Ceeb:

Q: Yij Lub Zog ("Qu" hauv Pinyin).

235: Yam tsawg kawg los kom muaj zog ntawm235 MPa(Tsawg dua li lossis sib luag rau 16 hli tuab).

B: Kev cuam tshuam ntawm+20 degree(KV2 ntau dua lossis sib npaug ntawm 27J).

Q345A

Lub hom phiaj: GB \/ T 1591 (Tsawg-alloy High-zog qauv hlau).

Kev sib faib: Cov hlau roj qis nrog cov hlau microalloying (piv txwv, MN, V, NB).

Cov Nta Tseem Ceeb:

Q: Xij zog zog.

345: Yam tsawg kawg los kom muaj zog ntawm345 MPa(Tsawg dua li lossis sib luag rau 16 hli tuab).

A: Qhov yuav tsum tau ua (lwm cov qib nyiam Q345B \/ C \/ D \/ E muaj kev ntsuas ntawm qis dua kub).

2. Tshuaj lom neeg sib xyaw (16 hli thickness, yeej muaj nuj nqis)

Q345A: MicroalyLying ntsiab (V, NB) Refine nplej thiab txhim kho lub zog \/ tawv.

3. Cov Khoom Siv Cov Neeg Kho Mob (16 hli Thickness)

Teem nqi	Yield zog (RES)	Lub zog tensile (RM)	Elongation (a,%)	Cuam Tshuam
Q235B	Ntau dua los yog sib npaug rau 235 MPa	370-500 mpa	Ntau dua los yog sib npaug rau 25	{{0 {0}} degree, ntau dua los yog sib npaug rau 27J (KV2)
Q345A	Ntau dua los yog sib npaug rau 345 mpa	470-630 MPa	Ntau dua los yog sib npaug rau 21	Tsis tas yuav tsum (qib A)

 

Q345Apub~ 47% Ntau Tshaj Tawm ZogTshaj Q235b, ua rau nws haum rau cov khoom hnyav.
