UB 406x178x67 s275jr \/ s355jr h steel profile
Cov Khoom Siv Qib Kawm Qib Kawm
S275JR H Nqaj profile: Qhov yooj yim Tsawg-carbon hlau, tawm los ntawm 275MPA, Haum rau Nruab Nrab Lo Loadarios.
S355jr H Qhov Hlau Profile: High-Zub Tshaj Plaws Dua Tshiab Tshaj Tawm, tawm los ntawm 355MPA, nrog kev tiv thaiv hnyav dua lossis defervation rau kev thauj khoom hnyav lossis muaj kev thauj khoom hnyav.
Daim ntawv qhia "JR" txhais tau hais tias cov khoom muaj kev cuam tshuam nyuaj ntawm ntau dua los yog sib npaug ntawm 20 degree xav tau.
Ua Thiab Vuam Cov Kab Mob
Cov txheej txheem: Ob cov ntaub ntawv muaj qhov cub txias txias, txiav thiab tsim cov khoom. S275JR muaj cov ntsiab lus roj carbon qis thiab zoo dua, uas haum rau kev ua cov txheej txheem kev ua kom yooj yim.
Weldability: los ntawm kev tswj cov ntsiab lus ntawm leej faj thiab phosphorus impurities, nws tsis yooj yim rau tawg thaum vuam, thiab nws cov pa thaiv cov txheej txheem.
Tsawg-kub nyuaj: s355jr h Seam Beam tseem tuaj yeem tswj tau ruaj khov nyob rau hauv tsawg ntawm cov securable kub (as degree) tuaj yeem tiv taus qhov kub me.
Daim Ntawv Thov Kev Ua Si thiab Qhov Zoo
Siv teb
S275JR HLAU H kem: Teeb lub Hoobkas thav duab, kev txhawb nqa choj ib txwm muaj, thiab lwm yam.
S355jr h nqaj: siab-nce lub tsev load-bearer qauv, loj khoom siv bracket, thiab lwm yam.
