S355j 0 h nqaj profile
S355J 0 h-nqaj?
S355J {0 h-nqaj yog lub siab-zog qauv txheej txheem sib xyaw ua raws li European tus qauv en 1 {0 25. Kev tsim qauv "S355" qhia tias tsawg kawg yog lub zog muaj zog ntawm 355 MPa, thaum "J0" qhia meej tus nqi tsawg kawg nkaus ntawm 0 degree, ua kom muaj kev nyuaj ntawm qhov kub tsawg.
Cov Khoom Siv Cov Khoom Siv
S355J {0 h Hom me me nqaj yog cov tshuaj steel tsawg yog cov tshuaj lom neeg tsawg nrog cov roj carbon, manganese, sidfur thiab phosphorus. Qhov sib ntxiv ntawm cov alloys txhim kho cov hlau lub zog, weldability thiab tawv.
Cov Khoom Siv Neeg Kho Tshuab
Tos lub zog: s355j 0 h-nqaj h-nqaj muaj tsawg kawg zog lub zog ntawm 355 MPa.
Lub zog tensile: lub zog tensile ntawm cov steel twg yog los ntawm 470 txog 630 MPa.
Kev Txom Nyem: nws elongation thaum tawg yog feem ntau nyob ib ncig 17-22%.
Kev Cuam Tshuam Tus nqi: J {{{{0}}}}}}}}}}}}}}}}}}}}} Koj muaj tus nqi tsawg kawg ntawm 27 J ntawm 0 degree.
Cov Ntawv Thov
S355J {{{1} h Hom nqaj feem ntau siv nyob rau hauv kev tsim kho cov txheej txheem, txuas hniav thiab cov qauv dav dav. Lawv kuj tau siv nyob rau hauv kev tsim cov tshuab hnyav, khoom siv khoom thiab tsev steel qauv.
Qhov Zoo
Lub zog siab: S355J 0 h zoo li tw muaj peev xwm ntau dua cov khoom siv qib qis dua.
Weldability zoo: Qhov muaj pes tsawg leeg ntawm cov hlau no tso cai rau kev siv vuam yooj yim nrog cov txheej txheem tsim nyog.
Tougness: j {0 cuam tshuam tus nqi kom ntseeg tau tias cov hlau khaws cia kub, ua rau kev siv hauv huab cua txias.
Nqi-siv tau: S355J {{{2} h-shaped steel muaj qhov sib npaug zoo ntawm tus nqi thiab kev ua tau zoo nyob rau ntau cov ntawv thov.
