Qhov txawv tseem ceeb
Lub zog: S460N muaj zog ntau dua nrog lub zog tawm los ntawm 460 MPa, piv rau S275N's 275 MPa yield zog (rau thicknesses txog 16mm).
Cov ntawv thov: S460N yog rau siab - kev xav tau muaj zog xws li cov tshuab hnyav, txuas hniav, thiab cov qauv ntawm ntug dej hiav txwv Arctic, thaum S275N siv dav hauv cov tsev thiab cov kav dej.
Kev ua tau zoo: S460N muab lub zog ntau dua - rau - qhov hnyav piv, tso cai rau cov qauv sib dua.
Zoo sib xws
Standard: Ob leeg yog normalized (N) structural steels los ntawm EN 10025-3, tsim rau zoo weldability thiab toughness nyob rau hauv txias tej yam kev mob.
Microstructure: Ob leeg muaj zoo -grain microstructures rau lub zog.
