Hlau s355j2g4

Cov Lus Qhia Yooj Yim

Cov Qauv Txheej Txheem:
S355j2g4 yog ahigh-zog qes-alloy (hsla) qauv hlauteev nyob rau hauv lubEuropean txheem en 10025-3: 2004(Kub-tsim qauv hlau steel). Nws yog tsim rau cov ntawv thov uas xav tauHigh Leput Zog, zoo heev kev muaj zog, thiab zoo weldability, tshwj xeeb hauv ib puag ncig txias.

 

Cov Khoom Siv Tseem Ceeb:

 

Paib lub zog: Tsawg kawg355 MPa(rau thickness tsawg dua los yog sib npaug rau 16 hli).

Kev muaj zog: Ua tau raws li kev cuam tshuam tiv thaiv kev xav tau ntawm-20 degree(V-thatch 冲击试验, yam tsawg kawg nkaus 冲击功 ntau dua lossis sib npaug rau 27 j).

Hwj txwv: Tsim nyog rau ntau cov txheej txheem vuam vim nws cov roj carbon sib npaug thiab tswj cov tshuaj muaj pes tsawg leeg.

Deagidation thiab Purity: Cais raws li aNkaus Nkhaus Hlau(G4) nrog kev tswj nruj nruj dhau ntawm kev tsis txaus siab (piv txwv li, leej faj, phosphorus), ua kom zoo sib xws hauv cov khoom siv neeg.

Tis npe txoj cai

 

Kev siv tshuaj lom neeg (raug)

Lub ntsiab	Cov ntsiab lus ntau (%)	Sau ntawv
Carbon (c)	Tsawg dua los yog sib npaug rau 0. 22	Kev tswj hwm lub hardness thiab weldability
Silicon (si)	Tsawg dua los yog sib npaug rau 0. 55	Txhim kho lub zog thiab deoxidation
Manganese (mn)	Tsawg dua los yog sib npaug rau 1.60	Txhim kho lub zog thiab hardenability
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0. 025	Kev txwv nruj txwv kom tsis txhob muaj brittleness
Sulphur (s)	Tsawg dua los yog sib npaug rau 0. 015	Txo cov sulfide suav nrog kev ua kom tau muaj zog
Aluminium (AL)	Ntau dua los yog sib npaug rau 0. 015 (soluble)	Siv rau deoxidation thiab grain refinement

 

 

Cov Ntawv Thov

S355J2G4 tau siv dav hauv:

 

Kev tsim qauv kev lag luam: Txuas hniav, vaj tse, thiab kev lag luam kev lag luam.

Cov Khoom Siv Neeg Kho Tshuab: Cov tshuab hnyav thiab lub tsheb.

Offshore thiab marine qauv: Qhov twg siab thiab corrosion tsis kam.

Txias Kev Siv Vaj Tse: Vim tias nws txoj kev ua tau zoo ntawm qhov kub tsawg.

 

 

 

Sib piv nrog cov qhab nia zoo sib xws

S355K2G4: Zoo ib yam li S355j2G4 tab sis nrogKev Xav Tau Ntau Cov Kev Xav Tau(feem ntau sim ntawm -20 degree nrog daim ntawv pov thawj stricter).

S355jr: Quality Toughness (Cuam Tshuam Tested ntawm +20 degree, haum rau cov chaw sov).

ASTM A572 Qib 50: Sib npaug Dan American HSLA hlau, tab sis nrog ntau qhov kev ntsuas sib txawv.

Cov Qauv thiab Ntawv Pov Thawj

Ua raws liEn 10025-3: 2004Rau cov tshuaj sib xyaw ua ke, cov khoom siv neeg kho mob, thiab kuaj.

Tej zaum yuav xav tau ntawv pov thawj ntxiv (piv txwv li, en 10204 3. 1 lossis 3.2) rau kev tsim nyog ua kom muaj kev ntsuas
