2 {{{4 4}} 3x102x23kg s355j0 \/ s355jr Universal nqaj txheem hlau qauv hlau
Cov Khoom Piav Qhia UB 203 × 102 × 23 h Seem Hlau Beob
Tus Qauv Cim: UB 203 × 102 × 23, qhov twg "×" sawv rau qhov siab ntev tshaj plaws yog qhov siab 203mm, thiab chav ntsuas qhov hnyav yog hais txog 23kg \/ m.
Cov Qauv Txheej Txheem: yoog rau European tus qauv en 1 {2}} 025, cov khoom siv yog S3555j0 lossis S355JR.
Khoom siv ntawm UB 203 × 102 × 23 h nqaj hlau qauv
Cov kev sib xws ntawm S355jr thiab S355J 0
Lub zog: tawm lub zog ntau dua los yog sib npaug rau 355mpa, tensile lub zog ntau 470 ~ 630MPA.
Toubse: kev cuam tshuam nyuaj ntawm chav sov (20 degree) ntau dua los yog sib npaug ntawm 27J (S355jr), nrog zoo deformation muaj peev xwm (elongation ntau dua los yog sib npaug rau 22%).
Weldability: txhawb nqa phau ntawv Vuam, Submerged Arc Vuam thiab lwm yam kev ua, thiab tsis muaj feem cuam tshuam tom qab vuam.
Tshwj xeeb ntawm S355J {1}}} nqaj hlau
Raws li kev sib txawv ntawm S355jR, nws yuav tau ua kom zoo rau qhov kub ntawm qhov kev cuam tshuam kub tsawg, tab sis tag nrho cov neeg kho tshuab zoo ib yam li S355JR.
Tshuaj Yeeb Nkab (Cov nqi raug) ntawm UB 203 × 102 × 23 qauv hlau HAR BEAM
S355jr h Beam khoom siv: carbon (c) tsawg dua lossis sib npaug ntawm {0. 025%, sulfur (s) tsawg dua lossis sib npaug rau 0.025%.
S355j {0 h hlau nqaj: Nruab nrab tsis muaj carbon monoxor (tsawg dua lossis sib luag rau deoxidation ntxiv dag zog.
Ua thiab Daim Ntawv Thov Kev Ua Haujlwm
Txias \/ kub kev ua: Yooj yim rau kev txiav, khoov thiab daim ntawv, txhawb nqa cov qauv kev lag luam siab.
Corrosion Kuj: Zoo corrosion tsis kam nyob rau hauv ib puag ncig huab cua, ib puag ncig tshwj xeeb (vaum, acidic thiab alkaline) yuav tsum muaj kev tiv thaiv.
Daim Ntawv Thov Cov Ntawv Thov: Siv tau rau High-Lool cov xwm txheej xws li cov ntas, Choj txhawb nqa, thiab cov khoom siv hnyav thiab hnyav thiab tiv thaiv kev nyab xeeb thiab kev nyab xeeb.
