1. Txheem thiab Qib Txheej txheem cej luam

Lub hom phiaj: Teev nyob rau hauvGB \/ T 1591-2018(Suav teb chaws txheem rau lub siab-muaj zog tsawg-alloy qauv hlau).

Kev sib faib: Belongs rauHSLA (High-Zog Tsawg-Alloy)Hlau, tsim los muab lub zog siab dua, zoo dua corrosion tsis kam, thiab txhim kho kev sib zog sib piv rau cov hlau me me, thaum ua kom muaj kev vam meej weldability thiab formatability.

Cov menyuam kawm qib: Tso cai los ntawm kev cuam tshuam Toughning thiab kev pabcuam kub:

Q355B: Chav-qhov kub cuam tshuam tsis kam (20 degree, ntau dua los yog sib luag rau 27J).

Q355C: {{0 degree cuam tshuam tsis kam (ntau dua lossis sib npaug rau 27j).

Q355D: {{-20 degree cuam tshuam tsis kam (ntau dua lossis sib npaug rau 27j).

Q355E: {{-40 degree cuam tshuam tsis kam (ntau dua lossis sib npaug rau 27j).
(Nco tseg: "Q" sawv ntsug rau "Qu 服强度" (tawm los dag zog), "355" qhia tsawg zog lub zog ntawm 355 MPa.)

Cov Nta Tseem Ceeb:

 

Microalloying: Siv NB (Niobium), v (vanadium), thiab ti (titanium) rau refine nplej thiab txhim kho lub zog yam tsis muaj txiaj ntsig zoo hauv cov ntsiab lus carbon.

Cov pa roj carbon tsawg: C Tsawg dua lossis sib npaug rau 0. 24% (Q355B) kom ua kom zoo weldability; Stricter txwv nyob rau qib siab (Q355C \/ d \/ e) txhim kho qis tsawg-qhov kub.

Cov ntawv tseem ceeb:

 

Paib lub zog: Tswj hwm ntau dua lossis sib npaug rau 355 MPa rau thicknesses tsawg dua los yog sib npaug rau 16 hli; txo qis me ntsis nrog kev nce tuab (piv txwv li, Q355B: 335 MPA ntawm 16-40mm Thickness).

Lub zog tensile: Ntau dua li cov hlau me (piv txwv li, Q235: 370-500 MPa), haum rau load-cov kabmob qauv.

Kev Cuam Tshuam: Qeb Q355C \/ E tseem ceeb rau cov cheeb tsam txias (xws li, Northeast Suav, siab tshaj plaws thaj chaw).

4. Cov yam ntxwv thiab cov ntawv thov

Cov ntsiab lus tseem ceeb:

Siab Zog: Txo cov kev siv hlau los ntawm 10-15% piv rau Q235 hauv cov qauv zoo sib xws, txo tus nqi thiab cov teeb meem hnyav.

Corrosion Kuj: MicroalyLying Ntsiab (Cu, CR, NI) txhim kho cov khoom siv cormospher tsis kam, zoo tagnrho rau sab nraum zoov qauv.

Hwj txwv: Qaub CEV tso cai rau kev siv vuam yooj yim uas tsis muaj preheating feem ntau (tuab tsawg dua lossis sib npaug lossis sib npaug ntawm {{1} degree).

Ductility thiab qaug zog tsis kam: Haum rau kev thauj khoom dynamic (piv txwv li, txuas hniav, cranes).

Cov Kev Siv Raug Raug:

Cov qauv loj loj: Cov chaw ua haujlwm, chaw nres tsheb hauv tshav dav hlau, thiab chav ua haujlwm (piv txwv li, Beijing Daxing Tshav Dav Hlau).

Tus choj: Txoj kev loj \/ Railway Txuas hniav (piv txwv li, Hong Kong-Zhuhai-Macao Choj siv Q355d \/ e).

Cov Khoom Siv Neeg Kho Tshuab: Cov tshuab hnyav hnyav, cov cuab yeej siv mining, thiab kev ua liajcural tshuab.

Zog Infrastructure: Cua turbine yees, lub zog cog cog cov qauv, thiab ntug dej hiav txwv.
