Cov qauv kev ntseeg tau ntawm txhua qhov kev tsim sab nraum zoov pob khawm ntawm cov khoom siv kho tshuab ntawm nws qib steel -tshwj xeeb tshaj yog rau Corten Steel, qhov twg lub zog, ductility thiab toughness yuav tsum ua raws li ob qho tib si corrosion kuj thiab fabrication xav tau. SMA400AP Corten Steel, qib flagship nyob rau hauv Nyiv JIS G 3114: 2022 tus qauv rau atmospheric corrosion-resistant welded structural steel, muaj nws cov core mechanical zog nruj me ntsis raws li tus qauv, txhua calibrated rau nruab nrab -load sab nraum zoov structural daim ntaub ntawv. Cov no tsis yog -kev sib tham, thickness- cov khoom nyob ntawm tsis yog tsuas yog cov kev qhia tshwj xeeb xwb- lawv ncaj qha txiav txim siab qib qhov weldability, formability thiab tiag - ntiaj teb cov qauv kev ua tau zoo. Cov lus qhia no rhuav tshem cov yam ntxwv tseem ceeb ntawm SMA400AP, lawv cov kev ua haujlwm zoo li cas thiab lawv ua raws li JIS G 3114: 2022 qhov kev ua tau zoo.
JIS G 3114: 2022 Mandated Mechanical Properties (Thickness-Nyob)
Tag nrho cov khoom siv SMA400AP yog lub Hoobkas- kuaj kom ua tau raws li cov kev txwv tsis siv neeg kho ib qho JIS G 3114: 2022, nrog rau kev ua tau zoo calibrated rau phaj tuab (qhov sib txawv ntawm cov qauv hlau tsim). Tsis muaj batch ntawm SMA400AP tau ntawv pov thawj rau kev siv tshwj tsis yog nws dhau qhov kev sim nruj rau cov yam ntxwv tseem ceeb no:
| Phaj Thickness Range | Yam tsawg kawg nkaus Yield Strength | Tensile Strength Range | Tsawg kawg Elongation | Charpy V-Ntshuam Impact Toughness (0 degree) |
|---|---|---|---|---|
| Tsawg dua los yog sib npaug li 16 hli | 245 MPa rau | 400-510 MPa | 26% | Ntau dua lossis sib npaug li 27 J |
| 16-40 mm | 235 MPa rau | 400-510 MPa | 27% | Ntau dua lossis sib npaug li 27 J |
| 40-100 hli | 215 MPa | 400-510 MPa | 27% | Ntau dua lossis sib npaug li 27 J |
Cov lus ceeb toom tseem ceeb: JIS G 3114: 2022 tswj hwm cov txiaj ntsig no rau txhua qhov kub - dov SMA400AP cov khoom, kom ntseeg tau tias kev ua haujlwm zoo ib yam thoob ntiaj teb kev xa khoom thiab kev tsim khoom.
Tswv yim Engineering cuam tshuam ntawm txhua yam khoom tseem ceeb
Txhua tus neeg kho tshuab zoo ntawm SMA400AP ua haujlwm rau lub hom phiaj tshwj xeeb rau kev tsim qauv sab nraum zoov thiab tsim khoom- tshem tawm kev kwv yees rau engineers thiab fabricators tib yam:
1. Yield zog (215–245 MPa)
Qhov no txhais qhov siab tshaj plaws load SMA400AP tuaj yeem dais yam tsis muaj deformation mus tas li, optimized raunruab nrab loads(qib tus qauv tsim tseem ceeb hauv JIS G 3114: 2022). Lub thickness -dependent txo yog tus qauv qauv steel engineering txoj cai, thiab qhov ntau kom ntseeg tau tias kev ua tau zoo rau qis - mus rau - nruab nrab -nce framing, cov neeg taug kev choj Cheebtsam thiab cov khoom siv hluav taws xob sab nraum zoov -tsis muaj lub zog ntau dhau (thiab tus nqi) siab dua - qib Corten hnyav hnyav rau unnee
2. Tensile zog (400-510 MPa)
Lub zog tensile ruaj khov thoob plaws tag nrho cov thicknesses lav cov hlau tuaj yeem tiv taus qhov kawg tensile kev nyuaj siab (xws li, cua loads, seismic kev ua, dynamic ua hauj lwm kev nyuaj siab) ua ntej fracturing. Ua ke nrog nws lub zog tawm los, qhov ntau yam no muab qhov sib npauglub zog - rau - ductility piv- tseem ceeb heev rau kev zam kom tsis txhob muaj qhov ua tsis tiav hauv kev siv sab nraum zoov.
3. Elongation (26–27%)
Qhov siab yam tsawg kawg nkaus elongation yog qhov zoo tshaj plaws ntawm SMA400AP, ua kom ncaj qhatxhim khu kev qha txias tsim thiab fabrication. Nws txhais tau hais tias cov hlau tuaj yeem khoov, dov thiab zoo li tus rau hauv cov txheej txheem kev cai (cov kab teeb nkhaus, kev txhawb nqa lub tsev, cov angular thav duab) yam tsis muaj micro- tawg lossis kev puas tsuaj - tsis muaj kev kho cua sov tshwj xeeb. Qhov no ua rau lub khw thiab ntawm - qhov chaw tsim khoom, txo cov kev ua haujlwm rov ua dua thiab cov sijhawm ua haujlwm.
4. Impact Toughness (Ntau dua lossis sib npaug ntawm 27 J ntawm 0 degree)
JIS G 3114: 2022 tswj hwm qhov qis- qhov kub thiab txias cuam tshuam los tiv thaiv kev tawg ntawm cov huab cua txias lossis siab - kev ntxhov siab sab nraum zoov. SMA400AP khaws nws cov ductility thiab cov qauv kev ncaj ncees thaum raug cuam tshuam tam sim lossis qhov kub thiab txias, tsis yog - qhov yuav tsum tau sib tham rau sab nraum zoov cov qauv hlau hauv thaj chaw kub thiab txias thoob ntiaj teb.
Yuav Ua Li Cas Cov Cuab Yeej Siv Tau Nrog SMA400AP Cov Khoom Siv Core
Cov neeg kho tshuab profile ntawm SMA400AP tsis yog arbitrary - nws yog engineered los ntawm JIS G 3114: 2022 kom phim nws cov zoo tagnrho sab nraum zoov cov ntaub ntawv siv:
Cov txiaj ntsig nruab nrab / lub zog tensile ua rau nws raug nqi -zoo rau qis- mus rau - nruab nrab- nce kev lag luam / kev lag luam framing, cov neeg taug kev txuas hniav thiab kev siv hluav taws xob txhawb nqa (tsis pub dhau - engineering rau lub teeb- rau - nruab nrab loads).
High elongation thiab cuam tshuam toughness txhawb kev cai fabrication thiab txhim khu kev qha kev ua tau zoo nyob rau hauv txawv txawv sab nraum tej yam kev mob.
Cov khoom siv ruaj khov thoob plaws thicknesses ua kom yooj yim rau kev tsim cov qauv kev suav, qhov txiaj ntsig tseem ceeb rau cov pab pawg engineering thoob ntiaj teb ua haujlwm nrog JIS, ISO lossis cov lej hauv cheeb tsam.
Qhov tseem ceeb, cov khoom no paub meej tias SMA400AP yogtsis haumrau siab -load daim ntaub ntawv (ntev- ncua kev loj choj, siab- nce lub tsev cores) uas yuav tsum tau ntau dua yield / tensile zog- rau cov no, siab dua -qib Corten Steel (xws li, SMA490AP) nyob rau hauv JIS G 3114:2022 yog qhov kev xaiv.
Key Takeaway rau Tus Qauv Tsim
SMA400AP Corten Steel's core mechanical zog, raws li tau hais nruj me ntsis los ntawm JIS G 3114: 2022, xakev ua tau zoo-profile optimizedrau nruab nrab-load welded sab nraum cov qauv kev ua haujlwm. Nws thickness -raws li lub zog ntawm lub zog, ruaj tensile lub zog, siab elongation thiab mandated low- kub cuam tshuam toughness tag nrho cov ua hauj lwm nyob rau hauv tandem los xyuas kom meej cov qauv kev ntseeg tau, yooj yim fabrication thiab zoo ib yam tiag tiag - ntiaj teb no kev ua tau zoo- yam tsis muaj nqi los yog ntau tshaj - engineering. Rau cov kws tsim qauv tsim sab nraum zoov tsim nrog lub teeb- rau- cov kev xav tau nruab nrab ntawm cov khoom thauj, cov khoom siv tshuab ua qauv no ua rau SMA400AP qhov kev kwv yees, code- ua raws thiab tus nqi- xaiv tau zoo rau cov haujlwm thoob ntiaj teb.
