MECHANICAL PROPERTIES
Vim qhov sib txawv ntawm cov tshuaj sib xyaw ntawm A36 thiab A572 steel, cov ntaub ntawv no txawv ntawm lawv cov khoom siv kho tshuab, suav nrog cov ntsiab lus tawm, uas ntsuas qhov taw tes ntawm cov khoom siv mus tas li hloov cov duab tom qab muaj zog loj, thiab lub zog tensile, uas ntsuas lub zog xav tau. ua rau cov khoom tawg lossis tsis ua haujlwm.
Qhov muaj ntau dua ntawm cov khoom siv ntxiv dag zog, xws li manganese thiab silicon, hauv A572 phaj qib muab cov khoom muaj zog dua piv rau A36. Lub zog siab dua no tso cai rau A572 steel dais hnyav dua thiab tiv taus ntau zog yam tsis muaj kev tawg lossis ua tsis tiav, uas yog qhov tseem ceeb hauv kev siv cov qauv.

KHOOM PLIG A572 STEEL Plate
Thaum siv nyob rau hauv qhov chaw txias dua, cov cuab yeej ua haujlwm tsim qauv tuaj yeem thov rau Charpy qhov kev sim ua rau ntawm A572 cov ntaub ntawv. Kev ntsuam xyuas Charpy ntsuas lub peev xwm ntawm cov khoom siv los tiv thaiv lub zog loj hauv qhov kub thiab txias, uas yog qhov tseem ceeb los xyuas kom meej cov khoom siv tsis tawg lossis ua tsis tiav hauv huab cua hnyav. Vim muaj cov khoom ntxiv dag zog ntxiv nyob rau hauv A572 steel, cov khoom siv no yuav haum rau cov huab cua txias dua li A36 steel.
Rau hnyav A36 thiab A572 steel phaj - uas yog cov ntaub ntawv phaj siab dua peb ntiv tes tuab - yuav tsum tau kuaj ultrasonic (UT). UTs siv cov kev sojntsuam xa cov suab nrov rau hauv cov khoom siv, uas rov qab los thaum kuaj pom qhov tsis txaus, ua rau nws muaj txiaj ntsig zoo rau cov ntaub ntawv tuab uas muaj qhov tsis zoo sab hauv yuav nyuaj rau kev kuaj xyuas.
A572 Hloov pauv tau?
Ob lub phaj A36 thiab A572 feem ntau yog siv rau hauv cov txheej txheem kev siv, uas suav nrog kev tsim choj thiab kev tsim vaj tsev, tab sis lawv tsis hloov pauv. Raws li kev sib tham, A572 steel muaj zog ntau dua thiab hnav tsis kam tshaj A36 steel, yog li nws yuav tsim nyog rau kev siv hauv kev siv hnyav hnyav, xws li siv hauv kev tsim cov kav hlau txais xov lossis cov khoom siv ua kom muaj zog loj.

A572 tus nqi sib txawv
Raws li tau hais ua ntej, A36 yog cov hlau uas muaj qhov tsawg kawg nkaus lub zog ntawm 36, 000 PSI. Qib no muab nws lub zog los ntawm kev sib xyaw ntawm carbon thiab manganese. Ntawm qhov tod tes, A572-50, piv txwv li, yog hom hlau uas muaj qhov tsawg kawg nkaus yield zog ntawm 50,000 PSI. Zoo ib yam li A36, nws siv cov pa roj carbon thiab manganese rau lub zog, tab sis nws kuj suav nrog cov alloys ntxiv xws li columbium lossis vanadium. Cov alloys ntxiv no txhawb nws lub zog tag nrho, ua A572-50 feem ntau tus nqi ntawm ib ncig ntawm 2.5% - 5% siab dua A36.
