Qhov twg tus qauv no zaum hauv daim duab loj dua
Thoob plaws North American tus qauv tsim, "HSS" yuav luag txhua zaus txhais tau tias lub raj tsim rau ASTM A500. Nws ua lub luag haujlwm tib yam uas EN 10219 ua si hauv European txias- tsim cov qauv ua haujlwm - tib yam kev tsim cov logic (coil steel, txias yob-tsim, hluav taws xob-kuj-welded), txawv kev xeem tswj, sib txawv cov rooj sib txawv, txawv qib {{7}. Yog hais tias ib qhov project spec hu rau EN lossis GB cov khoom siv hloov, A500 raj tsis yog ib qho kev hloov pauv tsis siv neeg - chemistry thiab mechanical thresholds tsis line up ib -rau-ib.
Plaub Qib, Hauv Cov Lus Nug
- Qib A- qhov lightest - txoj haujlwm xaiv. Lub zog tawm los qis dua, tab sis yooj yim rau txias - ua haujlwm ntxiv tom qab kev yuav khoom. Tsis tshua tau teev tseg rau thawj cov tswv cuab; ntau qhov uas lub raj yuav raug khoov ntxiv lossis tsim cov dej ntws.
- Qib B- qhov kev xaiv ua ntej rau feem ntau ntawm cov txheej txheem thav duab, kab, thiab cov khoom siv dav dav. Muaj zog txaus rau feem ntau cov rooj plaub, weldable tsis muaj cov txheej txheem tshwj xeeb hauv cov phab ntsa tuab, thiab qib feem ntau cov mills khaws cia hauv cov khoom lag luam tas mus li.
- Qib C- ib kauj ruam zuj zus nyob rau hauv ob qho tib si tawm los thiab lub zog tensile tshaj Qib B, ua tiav los ntawm kev sib zog me ntsis es tsis yog cov txheej txheem ntau lawm. Qhia tau hais tias thaum ib qho me me los yog cov phab ntsa nyias yuav tsum nqa ntau dua.
- Qib D- qib qis tshaj plaws, muab cov ductility siab dua ntawm qhov qis qis zog. Muaj txiaj ntsig zoo hauv cov xwm txheej uas cuam tshuam nrog cov ncej hnyav- tsim cov khoom tsim tawm, tab sis feem ntau tsis yog thawj qhov kev xaiv rau cov qauv tsim qauv.
Rau kev siv, qhov tsawg kawg nkaus lub zog tawm los ntawm kwv yees li 33 ksi (Qib A, puag ncig) mus txog 50 ksi (Qib C, zoo li seem), nrog lub zog tensile yam tsawg kawg nkaus ntawm 45 thiab 62 ksi nyob ntawm qib thiab cov duab - puag ncig thiab zoo li tus (square/rectangular) seem ntawmib yamqib tsis tau tuav kom zoo ib yam yield tsawg kawg nkaus, txij li qhov txias ntxiv - ua cov kauj ruam hauv shaping round raj rau hauv square lossis rectangular profile nce kaum lub zog.
Nco tseg: ASTM ib ntus hloov kho A500 (qhov tseem ceeb ntawm lub zog thiab qib kev pab cuam tau hloov pauv thoob plaws), yog li nco ntsoov paub tseeb tias tsab ntawv twg koj tus neeg muab ntawv pov thawj daim ntawv pov thawj es tsis xav tias cov nuj nqis tsis hloov pauv los ntawm cov ntaub ntawv qub uas koj tuaj yeem pom lwm qhov.
Dab tsi tiag hloov ntawm Qib, Tshuaj
Tag nrho plaub qib sib piv cov ntsiab lus zoo sib xws - carbon, manganese, phosphorus, thiab sulfur txwv nyob ze ntawm A, B, thiab D, nrog cov tooj liab ntxiv nyob rau hauv txhua qhov. Qib C nqaim cov pa roj carbon qab me ntsis piv rau lwm tus, uas yog ib feem ntawm nws ua tiav nws lub zog siab dua thaum tseem tuav tau weldability. Tsis muaj ib qho ntawm cov qib yuav tsum tau sib txawv alloying; qhov sib txawv ntawm lub zog yog los ntawm kev sib xyaw ua ke ntawm chemistry tswj thiab qib ntawm kev ua haujlwm txias qhia thaum lub sijhawm tsim, tsis yog los ntawm cov ntsiab lus alloy ntxiv.
Qhov twg txhua qib yuav tshwm sim
- Cov kab hauv tsev, bracing, thiab pem teb / ru tsev thav duab - dhau qib B
- Load-cov tswv cuab tseem ceeb uas txo cov raj hnyav los yog hneev taw tseem ceeb - Qib C
- Kos npe cov qauv, guardrail posts, ua liaj ua teb framing - Qib B, qee zaus Qib A
- Kev sib dhos yuav tsum muaj kev khoov sab nraud lossis coiling tom qab yuav khoom - Qib D
- Exposed architectural steel (railings, canopies, feature columns) - puag ncig Qib B yog ib yam rau nws cov profile huv si
FAQ
Q: Qhov txawv ntawm ASTM A500 Qib A, B, thiab C yog dab tsi?
A: Cov qib sib txawv feem ntau nyob rau hauv qhov tsawg kawg nkaus tawm los thiab tensile lub zog, nrog Qib B muab lub zog ntau dua li qib A, thiab Qib C muab qhov siab tshaj plaws ntawm peb. Qib B yog qhov feem ntau siv rau cov qauv steel hlau hauv North America, thaum Qib C raug xaiv thaum muaj peev xwm ntau dua qhov xav tau yam tsis muaj qhov seem loj.
Q: HSS yog dab tsi, thiab nws puas zoo ib yam li ASTM A500?
A: HSS (Hollow Structural Section) yog lub ntsiab lus North American rau cov qauv raj duab - round, square, thiab rectangular. ASTM A500 yog cov khoom siv tshwj xeeb uas HSS cov khoom lag luam feem ntau yog tsim los, yog li hauv kev xyaum "HSS" thiab "ASTM A500 raj" feem ntau siv sib hloov, txawm hais tias HSS tuaj yeem siv tau lwm yam kev qhia tshwj xeeb hauv cov xwm txheej tsawg.
Q: Vim li cas Qib D siv tsawg dua li Qib B?
A: Qib D muaj lub zog qis qis dua li qib B tab sis muaj nuj nqis rau nws cov ductility siab dua, ua rau nws tsim nyog rau cov ntawv thov uas muaj qhov tseem ceeb ntawm kev khoov los yog tsim tom qab lub raj raug tsim, es tsis yog rau cov qauv txheej txheem uas muaj zog ntau dua qhov feem ntau nyiam.
Q: TauASTM A500 1tube yuav welded?
A: Yog, ASTM A500 structural tubing yog tsim los kom yooj yim weldable siv cov txheej txheem vuam txheej txheem, thiab feem ntau welded rau hauv fabricated steel thav ntawv, kev sib txuas, thiab kev sib dhos.
