Thaum qhia txog Corten Steel rau kev thauj khoom-cov kabmob sab nraum zoov, cov khoom siv kho tshuab yog lub hauv paus ntawm txhua qhov kev nyab xeeb, tus nqi- siv tau, thiab cov cai- raws li kev tsim. Lawv hais tias qhov hnyav npaum li cas cov khoom tuaj yeem txhawb nqa, nws ua haujlwm li cas thiab vuam, nws ua haujlwm li cas hauv qhov kub thiab txias, thiab ntev npaum li cas nws yuav sawv mus txog qhov tiag -kev ntxhov siab hauv ntiaj teb. Rau ASTM A871 Qib 60- feem ntau siv cov qauv huab cua huab cua steel qib hauv ASTM A871/A871M tus qauv-txhua yam khoom siv tau nruj me ntsis kom sib npaug siab load peev xwm, fabrication yooj, thiab ntev -lub sij hawm durability rau unpainted sab nraum zoov kev pab cuam. Hauv qab no yog qhov tseeb, qhov kev tsom mus rau kev ua tiav ntawm nws cov khoom siv kho tshuab tseem ceeb, thiab lawv txhais tau li cas rau koj txoj haujlwm.
Yield & Tensile Strength: Tus Txheej Txheem Qib 60
Qhov kev xaiv "Qib 60" tuaj ncaj qha los ntawm cov khoom siv no tsis yog -cov kev xav tau ntawm lub zog sib tham, tau txiav txim los ntawm tus qauv tshiab ASTM A871/A871M-20:
Yam tsawg kawg nkaus Yield Strength (0.2% offset)415 MPa (60 ksi) rau phaj thickness txog li 100 hli (4 nti)
Tensile Strength Range485 MPa (70 ksi) yam tsawg kawg nkaus, 620 MPa (90 ksi) siab tshaj plaws
Tswv yim qhov nqi
Lub zog no ua tau zoo tshaj tus qauv A36 carbon steel (250 MPa yield) thiab architectural Corten qib zoo li ASTM A606 Hom 2 (345 MPa yield). Nws tso cai rau cov kws tsim khoom siv cov hlau nyias nyias, sib zog ua kom tau raws li cov qauv kev xav tau, txiav cov khoom ncaj qha, kev thauj mus los, thiab cov nqi teeb tsa. Lub zog zoo ib yam no kuj ua rau nws zoo tagnrho rau cov qauv tubular xws li cov khoom siv hluav taws xob, cov tuam tsev sib txuas lus, thiab kev txhawb nqa txoj kev loj, qhov chaw thauj khoom tsis sib xws yog qhov tseem ceeb rau kev tiv thaiv cua thiab kev ntxhov siab.
Ductility & Elongation: Fabrication & Damage Resistance
Raws li ASTM E8 / E8M tus qauv ntsuas tensile, ASTM A871 Qib 60 yuav tsum muajQhov tsawg kawg nkaus elongation ntawm 20% hauv 50 hli (2-nti) ntsuas qhov ntevrau longitudinal qauv.
Tswv yim qhov nqi
Elongation ntsuas cov khoom muaj peev xwm deform yam tsis muaj kev tawg, ua - lossis - tawg qhov zoo rau kev tsim khoom. Qib ductility no tso cai rau Qib 60 kom txias- tsim, dov mus rau hauv tubular seem, khoov, thiab welded yam tsis tau poob kev ncaj ncees. Nws kuj tseem ua rau cov hlau nqus cov khoom thauj sai sai heev- los ntawm kev ua seismic, cua daj cua dub, lossis kev cuam tshuam ntawm lub tsheb- tsis muaj kev puas tsuaj, qhov tseem ceeb ntawm kev nyab xeeb zoo dua li qis - ductility siab - lub zog steels.
Charpy V-Ntshuam Impact Toughness: Txias-Climate Reliability
Txhawm rau kom ntseeg tau tias kev ua haujlwm zoo ib yam hauv cov dej khov, ASTM A871 Qib 60 tswj hwm Charpy V-Notch (CVN) cuam tshuam kev ntsuas ib ASTM E23. Tus qauv xav tau aQhov tsawg kawg nkaus absorbed zog ntawm 27 J (20 ft-lbs) ntawm -18℃(0℃F)rau cov qauv ntev, nrog batch-rau-batch sib xws raug yuam.
Tswv yim qhov nqi
Qhov kev cuam tshuam toughness no tshem tawm qhov kev pheej hmoo ntawm qis- qhov kub thiab txias, qhov tsis ua haujlwm feem ntau rau cov pa roj carbon steel thiab qis dua - qib huab cua steels. Rau cov qauv teeb tsa nyob rau sab qaum teb, siab - thaj chaw siab, lossis qhov chaw uas muaj qhov tsis tu ncua - lub caij ntuj no txias txias, cov cuab yeej no tau lees paub xyoo - puag ncig kev nyab xeeb yam tsis tas yuav tsum tau tshwj xeeb qis- cov khoom siv kub hloov pauv.
Txias Bending Performance: Formability rau Custom Structures Shapes
ASTM A871 Qib 60 dhau qhov yuav tsum tau ua 180-degree txias khoov kuaj tsis muaj kev tawg lossis tawg. Rau daim hlau txog li 19 hli (0.75 ntiv tes) tuab, qhov yuav tsum tau khoov txoj kab uas hla sib npaug ntawm cov khoom tuab, nrog rau cov kev xav tau rau cov phaj tuab kom khaws cov formability.
Tswv yim qhov nqi
Qhov tseeb khoov qhov kev ua tau zoo muab qhov tsis sib haum xeeb fabrication yooj. Qib 60 tuaj yeem ua tau txias- tsim rau hauv cov kab kev cai, cov kab, cov ntu tubular, thiab cov duab nkhaus uas tsis muaj nqi kub ua haujlwm, ua kom lub sijhawm ntau lawm thiab txo cov nqi tsim khoom. Nws tawm tsam qhov tsis tshua muaj qhov sib npaug: cov qauv tsim muaj zog yam tsis muaj kev txi lub formability xav tau rau kev cai tsim qauv.
Tag nrho cov khoom tau raug lees paub nrog kev ntsuas tus qauv, thiab txhua pawg tsim khoom tau muab nrog Daim Ntawv Qhia Txog Mill Test (MTR) kom paub meej tias ua raws li ASTM A871 / A871M cov cai.
Hauv luv luv, cov khoom siv kho tshuab tseem ceeb ntawm ASTM A871 Qib 60 tau tsim tshwj xeeb rau kev siv sab nraum zoov Corten Steel. Tsis zoo li cov khoom siv hluav taws xob hluav taws xob zoo tshaj plaws rau kev zoo nkauj, Qib 60 sib npaug siab load peev xwm, fabrication yooj, txias - huab cua toughness, thiab ntev -lub sij hawm corrosion kuj-tag nrho backed los ntawm nruj ASTM cov qauv. Rau txhua qhov haujlwm uas xav tau qhov tsawg-kev tu, code- ua raws li cov qauv hlau rau kev pabcuam sab nraum zoov tsis muaj xim, cov khoom no ua rau ASTM A871 Qib 60 txhim khu kev qha, tus nqi- xaiv tau zoo.
