S355J2 yog European txheem alloy phaj, uas yog ib tug tsis tshua muaj alloy siab zog structural steel nrog zoo cuam tshuam toughness thiab vuam muaj nuj nqi.
S355J2 txais cov khoom siv hluav taws xob hluav taws xob, ua los ntawm cov hlau seem, steel zoo yog cov ntshiab, steel phaj yog nchuav nrog hlau, txias thiab nias rau hauv cov hlau tiaj tus. Nws yog tiaj, duab plaub, thiab tuaj yeem dov ncaj qha los yog sheared los ntawm dav hlau sawb. Hlau phaj los ntawm thickness, nyias steel phaj<8 mm (the thinnest 0.2 mm), medium-thick steel plate 8 ~ 60 mm, extra-thick steel plate 60 ~ 120 mm.
S355J2 steel phaj siv cov qauv: kev ua raws li EN10025-2: 2004. (Cov qauv qub EN10025: 1990) cov qauv.
S355J2 steel phaj xa khoom raws li txoj cai: steel phaj yog xa hauv kub dov, tswj khi, normalized thiab lwm lub xeev, thiab tseem tuaj yeem teev raws li cov kev xav tau ntawm lub xeev xa khoom.
