S275 dub me me steel rawsyog cov muaj zog thiab muaj ntau yam qauv steel ntu siv dav hauv kev tsim kho, engineering, kev tsim khoom, thiab kev lag luam.
Feem ntau hu ua U channels lossis C channels, cov seem no muaj cov channel -zoo li tus profile uas muab cov qauv zoo heev, qhov ruaj khov, thiab thauj khoom-cov kabmob txhawb nqa, thaum tseem tshuav qhov hnyav thiab yooj yim rau fabricate.
Ua los ntawm S275 qib me me steel raws li EN 10025-2, cov hlau me me dub muaj kev sib koom ua ke txhim khu kev qha ntawm lub zog, ductility, thiab weldability.
Qhov no ua rau lawv tsim nyog rau ob qho tib si cov qauv kev ua haujlwm thiab kev siv cov ntaub ntawv dav dav uas qhov kev ua tau zoo, kev siv nyiaj txiag, thiab kev ua haujlwm yooj yim yog qhov tseem ceeb.
Dub Mild Steel yog dab tsi?
"Dub" cov hlau me me yog hais txog cov hlau uas muaj xim grey tsaus los yog charcoal -xim xim tiav, tsim ib txwm thaum lub sijhawm kub dov. Thaum lub sij hawm kub dov, cov hlau yog tsim ntawm qhov kub siab tshaj nws cov recrystallization point, uas ua rau ib tug tawv txheej txheej ntawm zeb nplai.
Qhov no tiav:
Tshem tawm qhov xav tau kev kho saum npoo tam sim ua ntej fabrication
Muab kev tiv thaiv zoo thaum tuav thiab khaws cia
Nws yog qhov zoo tagnrho rau kev ua haujlwm ntxiv xws li txiav, vuam, drilling, thiab khoov
Txawm hais tias dub me me hlau tsis muaj kev tiv thaiv corrosion nyob rau hauv nws lub xeev tsis kho, nws yog feem ntau pleev xim rau, hmoov coated, los yog kub -dip galvanized tom qab fabrication rau sab nraum zoov los yog corrosive ib puag ncig.
Khoom Qib: S275 Mild Steel
S275 yog ib qho uas tsis yog- alloy, qis- carbon structural steel paub rau nws cov khoom sib npaug. Nrog rau qhov tsawg kawg nkaus lub zog ntawm 275 MPa, nws muaj lub zog siab dua S235 thaum tuav cov machinability zoo thiab weldability.
Muab nyob rau hauv kub dov mob, S275 dub me me steel channel muab kev ua tau zoo ib yam thoob plaws ntau yam ntawm cov txheej txheem thiab kev lag luam. Txheem: EN 10025-2
Qhov tseem ceeb ntawm S275 Dub Mild Steel Channel
Txheej Txheem & Kev Ua Haujlwm Zoo
Vuam: Zoo heev
Yooj yim weldable siv cov txheej txheem vuam yam tsis muaj preheating.
Machining / Sib Tsoo: Zoo
Haum rau kev txiav, drilling, milling, thiab kev cob qhia dav dav machining.
Khoov / Tsim: Ncaj
Nws tuaj yeem khoov thiab tsim nrog cov cuab yeej tsim nyog thiab radii.
Hnav Resistance: Ncaj
Tsim nyog rau kev siv cov qauv; tsis yog rau siab - daim ntawv thov kev puas tsuaj.
Corrosion Resistance: Tsis zoo (tsis kho) *
Kev tiv thaiv saum npoo yog pom zoo rau qhov chaw sab nraum zoov lossis qhov chaw ntub dej.
