ASTM A36 / A53 / Q235 / Q345 Carbon Hlau Lub kaum sab xis Bar

Cov pa roj carbon hlau steel lub kaum ntse ntse, txawv los ntawm lawv cov classic L-zoo li tus ntoo khaub lig-section, yog cov khoom siv tseem ceeb hauv ntau yam kev lag luam thiab kev tsim kho, muaj nuj nqis rau lawv qhov tshwj xeeb thauj khoom -cov kabmob muaj peev xwm, kev ruaj khov, thiab tus nqi- ua haujlwm tau zoo. Peb ASTM A36 / A53 / Q235 / Q345 carbon hlau steel lub kaum ntse ntse npog ntau yam ntawm cov khoom siv thoob ntiaj teb thiab lub teb chaws lees paub, ua tib zoo tsim kom tau raws li cov kev cai nruj ntawm cov phiaj xwm thoob ntiaj teb, ua rau lawv xaiv ntau yam rau engineers thiab manufacturers thoob ntiaj teb.

Kev suav nrog ASTM- cov ntawv pov thawj qib (A36 thiab A53) ua kom peb lub kaum ntse ntse ua raws li cov qauv ntsuas thoob ntiaj teb. ASTM A36, ib qho kev lees paub thoob ntiaj teb cov qauv hlau, khav theeb yam tsawg kawg nkaus lub zog ntawm 250 MPa thiab nthuav tawm zoo weldability, formability, thiab machinability. Qib no yog siv dav hauv kev siv cov qauv siv dav dav, xws li lub tsev thav duab, cov khoom siv choj, cov khoom siv hauv tsev, thiab cov khoom siv thauj mus los, qhov sib npaug ntawm cov khoom siv kho tshuab thiab kev siv ntau yam yog qhov tseem ceeb. ASTM A53, Ameslikas tau teev tseg rau seamless thiab welded steel kav, kuj tau yoog rau lub kaum ntse ntse siv hauv cov kav dej txhawb nqa, cov qauv hauv ntug dej hiav txwv, thiab kev siv dej hiav txwv. Nws muaj kev txhim khu kev qha tsis kam mus rau nruab nrab corrosion thiab cov qauv kev ntseeg siab, ua rau nws haum rau ib puag ncig uas muaj qhov sib txawv ntawm cov dej noo thiab tshuaj lom neeg.

Q235 thiab Q345, ua raws li cov qauv hauv Suav teb, yog cov qib tseem ceeb uas muaj npe nrov rau lawv cov kev hloov pauv hauv ob qho tib si hauv tsev thiab thoob ntiaj teb. Q235, cov pa roj carbon monoxide steel nrog qhov tsawg kawg nkaus lub zog ntawm 235 MPa, nta kev ua tau zoo thiab kev lag luam zoo. Nws yog dav siv nyob rau hauv lub teeb mus rau nruab nrab- lub luag hauj lwm structural Cheebtsam, xws li phab ntsa brackets, guardrails, qhov rooj thiab qhov rais thav ntawv, thiab lub teeb machinery qhov chaw. Q345, qis- alloy siab- lub zog hlau, xa cov kev ua tau zoo nrog qhov tsawg kawg nkaus lub zog ntawm 345 MPa, zoo dua qis- qhov kub thiab txias (dhau kev sim ntawm -20 degree), thiab txhim kho atmospheric corrosion kuj. Qib no yog qhov zoo tagnrho rau kev siv siab - kev ntxhov siab, xws li loj- lub tsev loj, hnyav- lub luag haujlwm choj, siab - nce lub tsev load-bearing thav duab, thiab cov khoom cog cog.

Tag nrho peb cov pa roj carbon steel lub kaum sab xis yog tsim los ntawm kev kub siab - dov txheej txheem. Thaum lub sij hawm tsim khoom, steel billets yog rhuab mus rau qhov kub thiab txias thiab tsim rau hauv L-zoo li tus ntoo khaub lig-section, uas refines cov khoom ntawm grain qauv, txhim khu kev sib xws, thiab boosts tag nrho lub zog thiab toughness. L-zoo li tus qauv tsim optimizes quab yuam faib, ua kom muaj txiaj ntsig hloov ntawm cov khoom ntsug thiab kab rov tav hauv cov txheej txheem. Tsis tas li ntawd, tus qauv tsim no ua kom yooj yim sib dhos thiab kev sib txuas nrog lwm yam khoom siv (piv txwv li, I-beams, channel steels, steel daim hlau) los ntawm vuam, bolting, lossis riveting, txhim kho kev tsim kho thiab kev tsim khoom.

Cov txheej txheem tswj xyuas nruj nruj tau siv thoob plaws lub voj voog tsim khoom kom lav cov khoom zoo. Los ntawm kev tshuaj xyuas cov khoom siv raw (tshuaj xyuas cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab) mus rau qhov tiag - lub sijhawm saib xyuas ntawm kub - dov tsis, thiab qhov kawg qhov tseeb qhov tseeb thiab kev kuaj pom qhov tsis xws luag, txhua pawg ntawm lub kaum sab xis tau soj ntsuam tag nrho. Qhov no ua kom tag nrho cov khoom ua tau raws li cov qauv kev cai, tsis muaj qhov tsis xws luag xws li cov kab nrib pleb, suav nrog, thiab cov tuab tsis sib xws, thiab tswj kev ua haujlwm zoo ib yam hauv kev siv kawg.

Peb cov ASTM A36 / A53 / Q235 / Q345 carbon hlau steel lub kaum ntse ntse ua haujlwm rau ntau qhov kev lag luam, suav nrog kev tsim kho, kev tsim kho vaj tse, kev tsim khoom siv tshuab, tsheb, thiab kev tsim khoom hauv hiav txwv. Txawm hais tias rau cov qauv tsim qauv lossis cov ntawv thov tshwj xeeb uas xav tau lub zog siab, kev tiv thaiv corrosion, lossis tus nqi-kev ua tau zoo, cov kaum sab xis no muab kev ntseeg siab, siab - zoo, thiab daim ntawv thov- cov kev daws teeb meem tshwj xeeb uas ua raws li cov qauv kev lag luam thoob ntiaj teb.
