High Strength S355J2 Structural Steel yog micro alloyed structural steel haum rau xws li kev siv tshuab engineering. Cov hlau muaj qhov zoo weldability nrog max CEV =0.47 rau txhua qhov sib txawv. Cov hlau tuaj yeem xa nrog cov khoom siv silicon tswj kom zoo galvanizing zog. Hauv qab no, ib tug xov tooj ntawm zoo sib xws variants nrog ntau yam cuam tshuam lub zog yog nthuav.
Cov tshuaj muaj pes tsawg leeg ntawm steel S355J2 raws li tus qauv ladle raws li GOST 10025-2, %
