Rau cov haujlwm me me sab nraum zoov-los ntawm lub vaj pergolas mus rau lub tsev me me-ntau cov fabricators thiab cov tswv qhov project xav yog tias lawv tuaj yeem hloov ASTM A606 Hom 2 Corten Steel rau ASTM A588 Qib B. Ob leeg yog huab cua- tiv taus Corten Steels, tab sis yog A606 Hom 2 ib qho kev hloov me me?{9} Lub ntsiab lus teb yog qhov tseeb:ASTM A606 Hom 2 tuaj yeem hloov A588 Qib B hauv feem ntau me me, tsis yog - hnyav- cov haujlwm thauj khoom, tab sis nws tseem ceeb heev kom phim cov qib rau koj qhov project qhov kev xav tau tshwj xeeb. Hauv qab no yog cov lus qhia luv luv, siv tau los pab koj txiav txim siab.
Qhov Tseem Ceeb Qhov Sib Txawv Ntawm Ob Qib Corten
Txhawm rau nkag siab yog tias qhov hloov pauv tau ua tau, ua ntej nkag siab lawv qhov sib txawv ntawm qhov tseem ceeb -ob qho tib si yog Corten, tab sis haum rau kev siv sib txawv:
ASTM A606 Hom 2: Lub teeb- ntsuas Corten (0.030–0.5 ntiv tes tuab), ua kom zoo rau kev siv vaj tsev. Yam tsawg kawg nkaus yield zog ntawm 345 MPa, nrog ib tug tooj liab - nplua nuj muaj pes tsawg leeg rau txhim khu kev qha atmospheric corrosion kuj. Nws ua tau zoo hauv kev ua haujlwm rau kev tsim qauv.
ASTM A588 Qib B: Heavy-cov haujlwm ua haujlwm Corten, muaj nyob rau hauv cov ntsuas tuab (txog li ob peb ntiv tes). Lub zog qis qis dua (345 MPa rau cov ntu nyias, mus txog 290 MPa rau cov ntu tuab) thiab txhim kho qhov txias txias (txog -20 degree), tsim rau cov khoom hnyav thiab huab cua.
Thaum ASTM A606 Hom 2 tuaj yeem hloov A588 Qib B (Cov Haujlwm me me)
Rau feem ntau me me, lub teeb -load tej yaam num, A606 Hom 2 yog ib qho kev hloov zoo meej - muab cov nqi txuag thiab kev ua haujlwm zoo dua:
Architectural Small Projects: Kho cov ntxaij vab tshaus, me me facades, vaj railings, thiab sab nraum zoov décor-A606 Type 2's workability thiab patina match A588 Grade B's aesthetic, tsis tas yuav muaj lub zog hnyav.
Lub Teeb Lub Teeb Me Me Cov Haujlwm: Cov pergolas me me, arbor thav duab, cladding kev txhawb nqa, thiab lub vaj txaj-A606 Hom 2 lub zog yog ntau tshaj li txaus rau cov khoom siv qis-load.
Ib puag ncig me me: Cov phiaj xwm hauv cov huab cua me me (tsis muaj huab cua txias lossis daus hnyav) - A606 Hom 2's corrosion resistance thiab toughness ua tau raws li qhov xav tau ntawm me me - nplai siv sab nraum zoov.
Thaum Nws Hloov Tsis Tau A588 Qib B (Critical Small Projects)
Tsis txhob hloov A588 Qib B nrog A606 Hom 2 hauv cov xwm txheej me tab sis siab -xav tau:
Hnyav-Load me Projects: Cov qauv me me uas txhawb nqa qhov hnyav (piv txwv li, me me choj railings, thauj khoom-cov kabmob vaj huam sib luag)-A588 Qib B qhov siab dua thiab ua haujlwm ntev yog qhov tsim nyog.
Ib puag ncig huab cua: Cov haujlwm me me hauv qhov txias txias (hauv qab -10 degree) lossis cov chaw ntug dej hiav txwv nrog cov ntsev ntsev hnyav-A588 Qib B's txhim kho corrosion thiab txias toughness outperforms A606 Hom 2.
Code-Yuav tsum tau Projects: Cov haujlwm me me uas yuav tsum tau ua raws li cov qauv txheej txheem qhia A588 Qib B (xws li cov qauv me me rau pej xeem)-ib txwm ua raws li cov cai.
Tswv yim tswv yim rau me me hloov qhov project
Rau cov haujlwm me me, nug ob lo lus nug yooj yim los txiav txim siab: 1) Puas yog qhov project xav tau kev thauj khoom hnyav-cov kabmob lossis cov kav ntev heev? 2) Puas yog nws khi los ntawm cov lej qhia A588 Qib B? Yog tias lo lus teb rau ob qho tib si yog "tsis yog," A606 Hom 2 yog tus nqi -hloov, ua haujlwm tau zoo uas muab tib yam Corten zoo nkauj thiab corrosion kuj.
Hauv luv luv, ASTM A606 Hom 2 tuaj yeem hloov A588 Qib B hauv feem ntau me me, lub teeb -load, tsis yog-code- txwv tsis pub ua haujlwm. Nws muaj kev ua haujlwm zoo dua thiab txuag nqi thaum tuav lub cim Corten patina- ua rau nws xaiv qhov zoo tshaj plaws rau kev tsim vaj tsev sab nraum zoov me me thiab cov teeb pom kev zoo.
