Raws li ib tug thawj coj exporter thiab chaw tsim tshuaj paus ntawm siab - zoo structural steel daim hlau, Gneesteel specializes nyob rau hauv tsim EN 10025-3 raws li cov ntaub ntawv, nrog rau cov qib S420N steel qib.
S420Nis ib qho zoo li qub-cov qauv hlau uas tsim los rau hnyav- cov haujlwm welded tsim uas yuav tsum tau muaj zog yield zog thiab zoo heev toughness, txawm nyob rau hauv qis kub.
Qhov zoo tshaj plaws rau cov txuas hniav, offshore platforms, cranes, thiab siab -nce vaj tse, peb S420N daim hlau raug xa mus rau hauv cov xwm txheej zoo (+N) kom ntseeg tau tias muaj kev sib txuas zoo thiab kev ua haujlwm zoo.
Rau cov lus qhia dav dav ntawm peb en 10025 3 cov txheej txheem steel phaj, tshawb xyuas peb cov ntau yam.

Cov ntsiab lus
TS EN 10025-3 S420Nis lub zog muaj zog zoo li qub nrog 420 MPa tawm los, 520-680 MPa tensile lub zog, thiab 40 J cuam tshuam ntawm -20 degree. Nws muaj superior weldability thiab toughness rau hnyav welded qauv. Rau -50℃daim ntawv thov, hloov mus rau S420NL.
FAQ:
S420N txhais li cas?
S= Qauv, 420=420 MPa tawm los, N=Normalized, kuaj ntawm -20℃.
Puas yog S420N zoo ib yam li S420NL?
Tsis yog - S420N raug kuaj ntawm -20 degree, S420NL ntawm -50℃rau kev siv arctic.
Dab tsi yog ASTM sib npaug ntawm S420N?
A572 Qib 65- normalized, 450 MPa tawm los.
Puas yog S420NC yog qib tiag?
Tsis yog - tej zaum yuav yog typo. Siv S420N lossis S420MC (thermomechanical).
S420N puas tuaj yeem welded yam tsis muaj preheating?
Yesup rau 50 hli vim CEV Tsawg dua los yog sib npaug rau 0.48; siv tsawg- hydrogen fillers.
