S355J2G3 Q345R Steel Angle

S355J2G3 Q345R Steel Lub kaum sab xis

S355J2G3 yog European txheem steel, muaj pes tsawg leeg yog: C Tsawg dua lossis sib npaug rau 0.20, Si Less dua lossis sib npaug rau 0.55, Mn Tsawg dua lossis sib npaug 1.60, P Tsawg dua lossis sib npaug rau 0.035, S Tsawg dua lossis sib npaug rau 0.035. Qhov pib ntawm S yog cov qauv hlau, 355 txhais tau hais tias qhov tsawg kawg nkaus tawm lub zog yog 355MPa.J2G3 txhais tau hais tias lub xeev xa khoom yog normalized, qhov cuam tshuam kev ua haujlwm ntawm -20 degree yog 27J, G3 thiab G4 yog lub ntsiab lus ntawm tus yam ntxwv ntawm hom deoxidation. S355J2G3 qhia tau hais tias semi-tua steel.Q355D yog cov hlau uas tsis tshua muaj siab-zog steel phaj, uas feem ntau yog siv rau hauv kev tsim cov tshuab tsim kev lag luam Piv txwv li; Crane, hydraulic xovxwm, siv machinery, hnyav machinery, choj qauv, lub taub hau, mechanical qhov chaw, steel qauv, loj forklift, ua liaj ua teb machinery, thiab lwm yam

1.Product Description

S355J2G3 low-alloy steel yog tsim raws li European qauv, uas yog me ntsis siab dua Q345 series steel phaj nyob rau hauv domestic GB / T1591-1994, thiab yog dav siv nyob rau hauv lub railway tsheb manufacturing kev lag luam.

Cov tshuaj muaj pes tsawg leeg ntawm S355J2G3 steel yog C Tsawg dua lossis sib npaug rau 0.20, Si Less dua lossis sib npaug rau 0.55, Mn Tsawg dua lossis sib npaug rau 1.6{{11 } }, P Tsawg dua lossis sib npaug rau 0.035, S Tsawg dua lossis sib npaug rau 0.035. Txoj kev deoxygenation FF.

Hauv kev hloov pauv ntawm qhov chaw qhuav thiab ntub dej, a-FeOOH tuaj yeem cuam tshuam qhov ntim hloov ntawm cov kab xeb, txo cov thermal stress ntawm xeb txheej thiab cov substrate, txhim kho cov adhesion ntawm xeb txheej, thiab yog li tiv thaiv cov oxide zaj duab xis. Nce, corrosion kuj ntawm steel yog txhim kho.

Nyob rau tib lub sijhawm, piv nrog Q345R steel, Cr cov ntsiab lus hauv S355J2G3 steel yog siab dua, thiab Cr muaj qhov cuam tshuam loj rau kev txhim kho lub peev xwm passivation ntawm cov hlau. Yog li ntawd, qhov corrosion kuj ntawm welded sib koom ntawm S355J2G3 steel yog zoo dua li ntawm Q345R steel.
