S3555jo yog ib hom siab - tawm los lub zog qauv txheej txheem teev hauv European txheemEN 10025-2, dav siv nyob rau hauv ntau yam engineering vim nws cov khoom siv neeg kho zoo tshaj plaws, Weldability, thiab versatility. Hauv qab no yog cov ncauj lus kom ntxaws ntawm cov hlau no:

Cov Khoom Tseem Ceeb Cov Khoom Siv

Paib lub zog: Ntau dua lossis sib npaug zos rau 355 MPa (rau thickness tsawg dua lossis sib npaug nrog 16-4 xyoos, ntau dua los yog sib npaug rau 31-63 hli).

Lub zog tensile: 470-630 MPa.

Kev ua siab loj: Elongation ntau dua los yog sib npaug rau 22% (rau thickness tsawg dua los yog sib npaug rau 16 hli), ua kom muaj kev tsim kom zoo.

Kev Cuam Tshuam: Sim ntawm0 Qib(denoted los ntawm "o" nyob rau qib) nrog tsawg kawg cuam tshuam lub zog ntawm 27 j, qhia txog qhov tsis txaus siab mus rau hauv qhov qis qis-}}}}}}}}}}}}}}}}}}}}}}}} kub ib puag ncig.

Tshuaj lom neeg tshuaj lom neeg (raug,% los ntawm qhov hnyav)

Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0.20% (cov ntsiab lus ntawm cov pa roj carbon ntau ntxiv).

Manganese (MN): 1.60% Max.

Silicon (Si): 0.55% Max.

Phosphorus (p): tsawg dua lossis sib npaug rau 0.035%.

Sulphur (s): tsawg dua los yog sib npaug rau 0.035%.

Ib txoj kab lus: Tej zaum muaj me me ntawm Niobium (NB), Vanadium (V), lossis Titanium (Ti) los ua kom cov qoob loo zoo thiab txhim kho lub zog.

Cov yam ntxwv tseem ceeb

High Leput Zog: Nws 355 MPa paib lub zog ntau dua li cov hlau me (piv txwv li cov kabmob tsis sib haum xeeb thiab cov txheej txheem kev ua haujlwm hnyav.

Zoo Weldability: Cov pa roj carbon tsawg thiab tswj cov ntsiab lus alloy tso cai rau kev siv vuam yooj yim

Muaj meej: Kev daws teeb meem nruab nrab ua rau nws khoov, dov, thiab txiav rau hauv cov duab nyuaj, yoog kom muaj kev tsim kho ntau yam.

Kev Cuam Tshuam: 0℃cuam tshuam kev ntseeg tau nyob rau hauv ib puag ncig nrog qee zaus txias, zam brittle tsis ua tiav nyob rau hauv dynamic poob.

 

 

 

 

 

 

Cov Ntawv Thov

S3555jo tau siv dav hauv kev lag luam uas yuav tsum muaj kev sib npaug ntawm lub zog, tawv, thiab weldability:

 

Kev tsim kho thiab vaj tse: Txuas hniav, siab {{}}} NCO SIV TSEV, kab teeb, thiab cov qauv kev txhawb nqa.

Neeg Kho Tshuab Engineering: Cheebtsam hnyav (Crane booms, excavator caj npab), muaj cov khoom siv thau khoom thau khoom thau khoom.

Automotive thiab Tsheb Thauj Mus Los: Cov chassis tsheb, cov thav duab tsheb, thiab cov tsheb ciav hlau tsheb ciav hlau.

Zog thiab Khoom Siv: Offshore platform Cheebtsam, cov hluav taws xob cog qoob loo, thiab xa cov raj xa dej txhawb nqa.

Marine engineering: Nkoj hulls, chaw nres nkoj cov khoom siv, thiab cov neeg ntug dej hiav txwv.
