Thaum xaiv Corten Steel rau cov haujlwm ua haujlwm, Q355GNH yog ib qho kev xaiv rau nruab nrab- daim ntawv thov kev ua haujlwm, thaum A588 Qib A (tus qauv los ntawm ASTM A588) nyiam rau nws cov huab cua tsis kam thiab pheej yig. Ntau tus neeg yuav khoom thiab cov neeg tsim khoom xav tsis thoob yog tias A588 Qib A tuaj yeem ua qhov hloov tau zoo rau Q355GNH. Puas yog nws muaj zog txaus rau cov khoom thauj khoom? Nws puas phim Q355GNH lub sijhawm ntev? Thaum twg yog qhov kev sib pauv ntse, thiab thaum twg nws txaus ntshai? Lub ntsiab lus teb yog qhov tseeb:A588 Qib A tuaj yeem hloov Q355GNH rau lub teeb-rau- nruab nrab siv cov qauv, tab sis tsis yog rau hnyav-load tej yaam num- muab cov khoom zoo sib xws corrosion, tus nqi zoo dua- ua tau zoo, tab sis qis zog yield zog. Hauv qab no yog cov lus qhia yooj yim, cov tswv yim.
Kev sib piv ceev: A588 Qib A vs. Q355GNH (Cov yam ntxwv tseem ceeb)
Ob qib sib qhia Corten Steel cov tub ntxhais corrosion kuj tab sis txawv ntawm lub zog - tseem ceeb rau kev siv cov qauv:
Yield zog: A588 Qib A muaj qhov tsawg kawg nkaus yield zog ntawm 345MPa; Q355GNH muaj 355MPa (qhov sib txawv 3%, tab sis muaj txiaj ntsig rau cov khoom hnyav).
Corrosion Resistance: Yuav luag zoo ib yam. Ob qho tib si tiv thaiv patinas, ua tau zoo nyob rau sab nraum zoov, nroog, thiab me me ntug dej hiav txwv ib puag ncig- tsis txawv ntawm qhov ntev - huab cua tsis kam.
Formability & Fabrication: A588 Qib A yog hloov tau yooj yim dua, yooj yim rau kev txiav, khoov, thiab vuam nrog cov cuab yeej txheem; Q355GNH yog me ntsis txhav, yuav tsum tau tshwj xeeb tuav tsawg heev.
Nqi: A588 Qib A yog 8-12% pheej yig dua Q355GNH, ua rau nws muaj peev xwm siv nyiaj - kev xaiv tus phooj ywg rau tsis yog - tej yaam num hnyav.
Thaum A588 Qib A tuaj yeem hloov Q355GNH
Xaiv rau A588 Qib A raws li kev hloov pauv kom txuag tau tus nqi yam tsis muaj kev cuam tshuam kev ua haujlwm, hauv cov xwm txheej no:
Lub teeb - mus rau - Cov Txheej Txheem Nruab Nrab: Guardrails, me me canopy thav duab, facade kev txhawb nqa, thiab lub teeb sab nraum zoov platforms -A588 Qib A lub zog 345MPa yooj yim ua haujlwm lub teeb.
Tsis yog -Kev siv tus qauv tseem ceeb: Cov khoom siv kho kom zoo nkauj (piv txwv li, vaj trellises, me me pavilion thav ntawv) qhov twg lub zog siab tshaj plaws tsis yog qhov yuav tsum tau muaj kev nyab xeeb.
Nyiaj txiag-Tight Projects: Thaum Q355GNH tsis xav tau ntxiv 10MPa yield zog, A588 Qib A muab tib yam corrosion kuj ntawm tus nqi qis.
Thaum Koj Yuav Tsum Tsis Hloov Q355GNH nrog A588 Qib A
A588 Qib A qhov qis zog tawm los txhais tau tias nws tsis tuaj yeem hloov Q355GNH hauv cov xwm txheej tseem ceeb no:
Hnyav-Load Structural Use: Cov txuas hniav loj, tuav cov phab ntsa, cov ncej hnyav hnyav, lossis kev txhawb nqa kev lag luam -Q355GNH's 355MPa yield zog yog yuav tsum tau kom tsis txhob khoov lossis kev ua haujlwm tsis zoo.
Cov qauv kev nyab xeeb tseem ceeb: Thauj khoom-cov kabmob uas txawm tias me me deformation tuaj yeem ua rau muaj kev pheej hmoo (xws li, cov neeg taug kev kev txhawb nqa, cov chaw nyob sab nraum zoov loj).
Ib puag ncig huab cua: Cov ntug hiav txwv hnyav lossis thaj chaw muaj kev lag luam hnyav -Q355GNH cov ntsiab lus siab dua me ntsis muaj qhov zoo dua corrosion tsis kam rau lub sijhawm ntev - kev ntseeg tau.
Tswv yim rau kev hloov kev txiav txim siab
Ua kom yooj yim rau koj xaiv nrog txoj cai ceev no: Yog tias koj cov khoom vaj khoom tsev dais lub teeb - rau - cov khoom nruab nrab (tsawg dua lossis sib npaug li 500kg ib ntu) thiab tsis muaj kev nyab xeeb- tseem ceeb, A588 Qib A yog qhov hloov pauv zoo. Rau cov khoom hnyav lossis cov qauv tseem ceeb, lo nrog Q355GNH.
Hauv luv luv, A588 Qib A yog qhov ua tau zoo hloov pauv rau Q355GNH hauv lub teeb- rau- cov haujlwm nruab nrab. Nws muaj kev tiv thaiv corrosion zoo sib xws, tus nqi zoo dua -kev ua tau zoo, thiab kev tsim khoom yooj yim dua- tsuas yog xaiv Q355GNH thaum hnyav hnyav lossis kev nyab xeeb tseem ceeb xav tau nws lub zog ntxiv.
