ASTM A572 vs ASTM A992 Wide Flange Beams: Qhov Sib Txawv Tseem Ceeb, Kev Sib Piv Lub Zog & Kev Xaiv Zoo Tshaj Plaws

Hauv cov tsev uas muaj cov qauv hlau niaj hnub no, covW-BeamsLub luag haujlwm ua tus tswv cuab tseem ceeb ntawm lub thav duab, uas kev xaiv cov khoom siv muaj qhov cuam tshuam loj rau kev nyab xeeb nrog rau tus nqi ntawm lub tsev. Dab tsi yog qhov sib txawv tseem ceeb ntawm ob tus qauv nrov tshaj plaws hauv kev ua lag luam tam sim no -ASTM A572 Qib 50thiabASTM A992Cov neeg ua haujlwm ntawm Royal Steel yog cov neeg txhais lus tseeb.

A992: Tus qauv kev lag luam tshwj xeeb tsim rau cov cav "wide-flange"

A572 Qib 50, txawm hais tias nrov hauv kev lag luam hlau, ASTM A992 yog 'tus qauv kub' rauW beamshnub no.

Qhov Sib Txawv ntawm Xovxwm thiab Hom KhoomA572 yog cov lus qhia dav dav rau cov phaj, cov tuav thiab lwm yam profiles tab sis A992 yog ib qho rau cov kabmob kub-dov dav-flange.

Kev Txhim Kho Tshuaj Lom ZemA992 muaj zog dua hauv cov tshuaj lom neeg, ua rau cov hlau zoo dua los ntawm kev ntxiv cov khoom siv sib xyaw ua ke (vanadium, niobium, tooj liab thiab nickel).

Kev sib piv kev ua tau zoo tseem ceeb: Vim li cas A992 maj mam hloov A572?

Hauv kev tsim qauv, A992 qhia tau tias muaj txiaj ntsig zoo:

Kev Tswj Xyuas Qhov Sib Piv ntawm Yield-to-TensileA992 qhia txog qhov siab tshaj plaws ntawm qhov sib piv ntawm cov khoom siv thiab cov khoom siv tensile uas tsis pub tshaj 0.85. Qhov kev ywj pheej zoo no ua rau nws zoo dua hauv cov tsev uas yuav muaj av qeeg, ua rau nws nqus tau lub zog zoo dua.

Kev vuam tauVim yog A992 qhov kev txwv siab dua ntawm cov pa roj carbon sib npaug, nws qhov kev vuam tau ruaj khov dua li A572, ua rau txo qis kev pheej hmoo ntawm kev tawg vuam.

Lub zog sib xwsA992 qhia txog qhov tsawg kawg nkaus ntawm lub zog tso zis ntawm 50 ksi (kwv yees li 345 MPa) thiab teeb tsa qhov siab tshaj plaws ntawm lub zog tso zis, kom ntseeg tau tias muaj kev kwv yees tseeb ntawm kev ntxhov siab thaum lub sijhawm tsim qauv.

Kev muab khoom lag luam thiab daim ntawv pov thawj ob zaug

Ua ib lub tuam txhab muab hlau thoob ntiaj teb, Royal Steel tau ua raws li cov hauv qab no hauv nws cov haujlwm xa khoom tawm:

Tus Qauv TxheemHauv kev lag luam khoom siv hauv tsev zoo tshaj plaws hauv North America thiab Latin America,Hlau Flange Dav Davfeem ntau suav tias yog A992.

Daim Ntawv Pov Thawj Ob LeegFeem ntau cov hlau A992 zoo tshaj plaws hauv kev ua lag luam kuj ua tau raws li qhov yuav tsum tau ua ntawm A572 Qib 50. Qhov no txhais tau tias cov neeg siv khoom yuav A992 feem ntau tau txais cov khoom zoo dua piv rau A572.

Cov Lus Qhia ntawm Royal Steel

"Thaum xaivdav flange beams"Yog tias koj qhov project muaj kev vuam hlau nyuaj lossis nyob hauv thaj chaw uas muaj av qeeg, A992 yog qhov kev xaiv thawj zaug uas tsis muaj kev sib cav," tus thawj coj ntawm Royal Steel's International Trade Department tau hais.

Tam sim no,Tuam Tshoj Royal Steeltswj hwm kaum txhiab tons ntawm A992 thiab A572 cov lus qhia hauv Tshuag ntawm cov chaw nres nkoj xws li Tianjin, Qingdao, thiab Shanghai. Nrog 12 xyoo ntawm kev paub hauv kev xa tawm hlau, peb tsis tsuas yog muab cov khoom zoo uas ua tau raws li US ASTM cov qauv, tab sis kuj muab kev txhawb nqa kev cai raws li peb cov neeg siv khoom xav tau.
