EN 10025-2 S355J3G3 Cov Txheej Txheem Steel Hlau Phaj

Raws li ib qho ntawm cov ua lag luam, cov xa tawm, thiab cov xa khoom GNEE paub txog kev pabcuam cov phiaj loj tshaj plaws thoob ntiaj teb.Tus txheej txheem steel s355j3g3 daim hlauYog ib qho yooj yim rau ntaub thiab txiav raws li qhov tsim nyog tsim qauv. Peb tsim cov khoom lag luam no siv S355j2G3.

Tus qauv hlau no tsis yog -} cov hlau alleoy. EN 10025: 1990 yog tus qauv hlau. Tus txheej txheem tam sim no rau cov phiaj hlau no yog EN 10025-2: 2004.

Cov phiaj no yog li sim ntawm -20 centigrade los ntsuas lawv cov kev cuam tshuam tsis kam. Lub corrosion corrosion desistance yog qhov dav dav qib rau cov phiaj hlau tsim.

S355j2G3 {{- rolled cov paib yog li ua rau pom zoo corrosion. Qhov no tuaj yeem pom muaj ntau yam ntawm ib puag ncig loj. Ob qho tib si txo thiab oxidizing ib puag ncig tsis muaj teeb meem rau cov phiaj no. Lawv tuaj yeem tiv thaiv cov tshuaj siab, suav nrog cov nyom thiab feem ntau lom. Nitric, organic, inorganic, sulphuric, acetic, formic, chlorides, hydrochloric acid, and phosphoric acid show no impact on these plates due to their exceptional resisting abilities. Tsis tas li, lawv tau zoo rau kev ua haujlwm hauv kev ntxhov siab corrosion cracking, crevice, thiab pitting ib puag ncig. Lub tuam txhab muaj ntau qhov ntev ntev, cov qauv, cov kev qhia tshwj xeeb, thiab cov qauv. Cov lag luam no ntau los ntawm theem pib xws li muaj qab zib, mis nyuj, textile, tshuaj tua hluav taws, chiv, chiv, thiab ntau dua.

Li no,Ntug dej ntawm steel s355j2g3 daim hlauMuaj kev thov zoo hauv kev lag luam marine. Marine dej hauv kev corrosion tsis yog ib qho teeb meem rau cov phiaj no, tshwj xeeb tshaj yog cov kev mob crevice. Kev cuam tshuam zoo muaj zog thiab yooj yim weldability yog cov yam ntxwv ntawm cov phiaj ntawm cov kab ntawm sub- xoom} xoom} xoom.

Qub thiab tsis tau kho yog cov xwm txheej uas peb tau muab cov phiaj xwm no. Kev hloov kho me ntsis yog ua tiav hauv qee cov qauv ntawm cov phiaj no. Txij li thaum lawv yog lub tsho thiab ruaj khov, cov phiaj ntev ntev dua.

Ntawm GNE, cov kev ntsuam xyuas zoo tau ua los xyuas qhov ua txhaum, cov yam ntxwv, thiab cov khoom ntawm cov phiaj. Ob qho kev xeem ntawv thiab cov ntaub ntawv ntsuas tau ua rau ntawm cov phiaj no. Hardness kev ntsuas, hydro kuaj, flaring kuaj, fileGraphy, fartuctive chanting, thiab kev ntsuam xyuas / tsis yog} kev ntsuas yuav poob rau hauv kev ntsuas kev ntsuas. Cov ntaub ntawv ntsuas suav nrog cov ntaub ntawv kev kuaj, teeb meem corrosion, iGC, tshuaj lom neeg cov tshuaj ntsuam xyuas, thiab ntau dua.

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S3555555j3g3 yog qhov zoo rau lub zog, kev nruj, thiab weldability, nrog cov pa roj carbon tsawg los tiv thaiv brittleness. Cov lus hauv qab no qhia cov cim uas raug (% los ntawm qhov hnyav) raws li ib tus qub EN 10025 Txuj Ci:

Cov ntawv tseem ceeb:

Carbon (c): Txwv rau 0.20% los xyuas kom meej zoo weldability thiab ductioning, tiv thaiv kev ua kom tawv tawv nyob rau hauv tshav kub}}} kev cuam tshuam cheeb tsam thaum muaj kev cuam tshuam.

Manganese (MN): Txog li 1.60% txhim kho lub zog thiab tawv, tseem ceeb rau load {{1} {cov khoom siv cov kabmob.

Phosphorus (p) thiab Sulphur (s): Ob leeg capped ntawm 0.035% txhawm rau txhim kho kev cuam tshuam tiv thaiv thiab txo qhov kev ua phem, tshwj xeeb tshaj yog rau kev tsim qauv J2.

Nitrogen (n): Tswj tau ntawm 0.009% max txhawm rau txhawb cov qauv zoo nkauj zoo, pab tau cov qub (G3).

Qhov no muaj kev sib xyaw ua kom muaj tseeb s355j2g3 yog qhov qis - cov hlau almoy nrog cov ntawv muaj zoo heev. Gnee cov paib yog tsim nrog cov tshuaj tswj kom meej, feem ntau tshaj cov qauv tsim nyog rau kev ua tau zoo. Rau cov qib qis, kuaj xyuas EN 10025-2 S275JR lossis EN 10025-2 S275J0 hlau.

S355j2G3g3 cov khoom pov thawj muaj cov khoom siv muaj zog, haum rau kev tsim kho cov txheej txheem. Cov lus hauv qab no ua rau nws cov phiaj tseem ceeb rau cov phiaj rau 16 hli tuab, raws li ib tus qauv qub EN 10025 yuav txawv nrog tuab):

Cov ntawv tseem ceeb:

Paib lub zog: 355 MPA MIN tso cai rau high {1} kev siv cov ntaub ntawv, nrog cov nqi qis dua rau cov phiaj thicker (piv txwv li 345 mpa rau 16-40 mm).

Lub zog tensile: 490-630 mpa muab kev tiv thaiv zoo heev kom tawg hauv nro.

Elongation: 22% ua kom nruj kev ductility rau kev ua thiab vuam.

Kev Cuam Tshuam: 27 J ntawm -20℃tau lees tias mus rau brittle tsis ua tiav nyob rau hauv txias, tus yuam sij rau sab nraum zoov qauv.

Kev nyuaj: 150-200 HB qhia tias hardness, yooj yim tshuab thaum ruaj khov.

Qhov qub (G3) rov qab kho cov qauv nplej, txhim kho cov khoom no piv rau li- rolled steels. Rau cov khoom muaj zog dua, xav txog ER 10025-2 S355K2 lossis EN 10025-2 S450J0 hlau los ntawm GNEE.

S355J2G3 has excellent weldability due to its low carbon equivalent (CEV max 0.45 for thicknesses up to 30 mm), allowing for welding without preheating in many cases. It is compatible with common welding methods like SMAW (using low-hydrogen electrodes such as E7018), GTAW, and SAW. For thicker plates (>40 mm), preheating rau 100-150 qib yog pom zoo kom tsis txhob tawg hauv tshav kub- beur Feurs Zoov (Hz).

Fabrication thaj chaw suav nrog zoo machinability thiab formability, nrog li qub (G3) Txo cov kev ua kom zoo thaum tshav kub. Tshaj tawm - Weld Kev Kho Cua Sov (PWHT) ntawm 600-650 Qib yog qhia rau kev ntxhov siab nyem hauv ASME-}} coded application. Gnee's S35555J3g3 daim hlau tau muab nrog cov kev ua tau zoo rau kev ua kom zoo rau vuam, zoo ib yam li EN 10025-2 S235J2 tab sis muaj zog dua.

S355j2G3 yog ntau yam thiab dav siv hauv cov ntawv thov kom muaj zog thiab tawv:
