S355jr \/ s355J 0 h homuam khoom siv Beooj
S355jr nqaj hlau: Nws yog lub siab-zog qis-alloy qauv hlau nrog cov ntsiab lus carbon nrog {}}. 24%. Nws muaj qhov cuam tshuam zoo thiab ua tau zoo nyob rau hauv ob chav thiab tsawg zaus kub. Nws yog qhov tsim nyog rau cov qauv uas tau siv lub nra hnyav thiab lub sijhawm, xws li txuas hniav, lub tsev nce siab, thiab lwm yam .; Lub zog tensile feem ntau 470-630 MPa, thiab cov txiaj ntsig lub zog yog 355MPA.
S355J {0 steel nqaj: nws kuj yog lub siab-muaj zog qis-alloy txheej txheem steel nrog cov ntsiab lus carbon nrog {4}}. 23%. 23%. Nws lub zog yog qis dua qhov ntawd ntawm S355jr, tab sis nws cov plasticity thiab tawv muaj zoo dua qub, thiab nws cov kev cuam tshuam nyuaj yog qhov tsawg. Nws yog qhov haum rau kev tsim kho thiab engineering tej yaam num nyob rau hauv cov kev ua haujlwm dav dav, xws li lub tsev qauv, kev muaj khoom siv, thiab lwm yam; Nws lub zog tensile feem ntau {{{}} MPa, thiab nws cov txiaj ntsig lub zog yog 355MPA.
Cov yam ntxwv ua tau ntawm S3555jr \/ s355J {2}} h hom steel nqaj
Lub zog siab: nws muaj cov txiaj ntsig siab lub zog thiab tensile lub zog, tuaj yeem tiv thaiv cov nra loj loj, thiab muaj zog txhim khu kev qha loj rau cov qauv.
Zoo toughness: s355jr tseem muaj kev cuam tshuam zoo ntawm cov kub tsawg; S355J {0 muaj kev cuam tshuam zoo ntawm chav nyob, tuaj yeem tiv xwm qee yam cuam tshuam thiab txo qhov kev pheej hmoo ntawm nkig kev puas tsuaj rau tus qauv.
Zoo heev Vuam Kev Kawm: Lub Alloy keeb kwm kev sib piv yog tsim nyog, nws yog qhov yooj yim rau kev sib tw thiab tuaj yeem kho vuam zoo thiab txo qhov tsis xws luag.
Zoo dua corrosion Kuj: piv nrog rau cov pa roj carbon hlau, kev yauv tau txhim kho thiab lwm yam, tab sis nws tseem xav tau kev kho mob hauv txoj kev nyuaj siab.
Cov chaw thov ntawm s3555555jr \/ s355j {2}} steel nqaj h
S355JR H Profile Steel: Nws feem ntau siv nyob rau hauv cov sij hawm muaj rau lub zog thiab cov khoom siv hluav taws kub, choj tsim kho, thiab lwm yam.
S355J {{0 h nqaj seem: nws yog dav siv nyob rau hauv dav hlau qauv qauv, kev siv cov nroj tsuag, machinery manufacturing thiab lwm hom teb. Nyob rau hauv tsev qauv qauv, nws tuaj yeem siv rau kab teeb, kab thiab cov qauv qauv; Hauv cov nroj tsuag muaj kev muaj, nws tuaj yeem siv ua qauv kev txhawb nqa; Hauv kev tsim khoom machinery, nws tuaj yeem siv los tsim cov tshuab tshuab uas dais qee yam thauj khoom.
UB 457X91X91X98 LAWV STEEL STARCE BOOB thiab S355J {5}} Cov nqaj hlau ua rau qee qhov chaw muaj peev xwm siv tau. Yog tias nws yuav tsum tau siv nyob rau hauv ib puag ncig txias, xws li hauv qab {{{7} qib rau lub sijhawm ntev, s355j2 thiab lwm tus yog qhov tsim nyog rau cov chaw qes.
