ASTM A36 and ASTM A572 are two popular types of structural steel, suitable for use in applications such as bridge and building construction, energy, industrial manufacturing, road plate and more.
Ib cag ntawm ob qho tib si tau dav - siv qib, A572 thiab A36 sib txawv muaj zog hauv lawv lub zog, tshuab luam ntawv thiab muaj pes tsawg leeg. Cov kev sib txawv no tuaj yeem cuam tshuam rau cov neeg yuav txiav txim siab ntawm cov khoom siv los siv hauv lawv qhov project. Kab lus no yuav tshawb txog cov kev zoo sib xws thiab sib txawv.
A36 & A572 Khoom Siv Tshwj Xeeb
Cov menyuam kawm qib
A572 Cov Khoom Siv Hlau Tshwj Xeeb muaj tsib qib kawm tau 5 xyoos kawm qib 55, qib 6 thiab qib kawm tau sib txawv me ntsis kev sib txawv thiab cov khoom siv mechanical. A36 Steel phaj specification, ntawm qhov tod tes, tsis them ntau cov qib.
Tshuaj Muaj Tshuaj
A36 phaj yog suav tias yog cov pa roj carbon tsawg, lossis me, txhais tau tias nws muaj cov pa roj carbon ntau ntawm 0.05% rau 0.25%. Cov pa roj carbon qis ntawm A36 lub phaj ua rau nws yog ib qho ntawm cov hlau feem ntau - lossis cov tshuaj carbon, txhais tau yooj yim rau cov khoom siv thiab lub tshuab ua ntau yam qauv qauv.
A572 kuj yog cov hlau me me, tab sis qhov ntxiv ntawm qee cov tshuaj alloys - manga} {{{1} {{1} {{2} Nws muaj qhov hnyav dua rau cov hlau me me. Cov khoom siv no ua A572 zoo tagnrho rau kev siv cov ntawv thov txheej txheem uas xav tau lub peev xwm tiv thaiv kev ntxhov siab ntau, xws li txuas hniav thiab kis tus yees duab thiab xa cov yees.

Cov Khoom Siv Neeg Kho Tshuab
Vim tias qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm A36 thiab A572 sib txawv, suav nrog cov khoom siv tau ua tiav, suav nrog lub zog, uas ntsuas lub zog xav tau los ua cov khoom tawg lossis ua tsis tiav.
Qhov siab dua ntawm cov muaj zog dua qub, xws li manganese thiab silicon, hauv A572 Pug Qib Muab cov khoom siv ntau dua piv rau A36. Qhov siab dua no lub zog tso cai rau A572 hlau kom muaj qhov hnyav dua thiab tiv thaiv ntau dua cov yuam sij tsis muaj kev sib tsoo lossis qhov tseem ceeb hauv cov ntawv thov txheej txheem.
