S355NL vs S355J2: Weldability
S355NL vs S355J2 weldability yog ib qho tseem ceeb thaum xaiv ntawm cov qauv steels raws li EN 10025 tus qauv. S355NL, tau teev tseg raws li EN 10025-3, yog qhov zoo ib yam zoo-cov hlau ua kom zoo rau qis- qhov kub thiab txias, thaum S355J2, nyob rau hauv EN 10025-2, yog cov kub dov tsis-alloy steel rau kev siv dav dav. Qhov sib txawv ntawm S355J2 thiab S355NL nyob rau hauv weldability stems los ntawm lawv cov tshuaj muaj pes tsawg leeg thiab ua, cuam tshuam fabrication yooj yim thiab kev ua tau zoo nyob rau hauv welded lug.
Kab lus no sib piv lawv cov weldability, tshuaj muaj pes tsawg leeg, txhua yam khoom, thiab kev siv, hais txog cov ntsiab lus tseem ceeb s355nl vs s355j2 thiab qhov sib txawv ntawm s355j2 thiab s355nl. Yog xav paub ntxiv, mus saib peb EN 10025-3 S355NL normalized structural steel phaj.

Lub zog: Ob qib muaj cov txiaj ntsig zoo ib yam (355 MPa) thiab lub zog tensile (470-630 MPa) rau cov tuab zoo sib xws, ua kom muaj peev xwm sib piv.
Toughness: Qhov sib txawv ntawm S355J2 thiab S355NL yog toughness. S355NL's -50℃xeem (Ntau dua lossis sib npaug ntawm 27 J) ua rau nws zoo tagnrho rau cov huab cua txias, thaum S355J2's -20℃tests suits me me.
Thickness Range: S355NL txhawb nqa txog li 250 hli nrog cov khoom muaj zog tsawg- kub; S355J2 txog 250 hli tab sis nrog kev ua haujlwm txias tsawg.
