ASTM A992 raug suav tias yog hloov rau A36 hlau nyob rau hauv ib tug xov tooj ntawm kub dov steel qauv qauv steel qauv.
Cov khoom siv mechanies tsis zoo ib yam, txawm hais tias lawv zoo sib xws. A36 steel muaj tsawg kawg lub zog ntawm 36ksi thiab qhov kawg tensile lub zog ntawm 58, {3, {5}} psi.
Lub caij no, A992 muaj lub zog ua kom lub zog ntawm 50 ksi (yam tsawg kawg nkaus) thiab lub zog kawg ntawm 65 ksi (yam tsawg kawg nkaus). Hauv lwm lo lus, A992 muaj lub zog tsawg dua muaj zog. Txaj nyem ntawm qhov tawg yog hais txog tib yam, 21% rau cov tib yam li 2 nti tuab, txawm tias yog ib qho ntxiv me ntsis hauv cov ntu (txog li 8%) ntawm 20% vs. A992 18%.
ASTM A36 thiab A992 tsis yog tshuaj tsis zoo ib yam, txawm hais tias lawv zoo sib xws. A36 tso cai rau cov plaub hau ntau dua cov roj carbon tsawg kawg ({}}. 29%}. 23%}. 4%}.
A36 siv me ntsis tsawg heev manganese (pab tau rau kev tswj hwm sulphur impurities), thaum A992 tso cai rau ob qho tib si manganese thiab ntau dua leej faj. A992 yuav tsum yog qhov ntau ntxiv weldable tshaj li A36, thiab hais txog kev tua tuag (deoxidized) hlau thaum A36 nplooj Deagidation qhib.
Yog li, yeej ob qho tib si yog kaw, txawm ntau tshaj tawm, thiab A992 tau siv los hloov A36 hauv ntau cov ntawv thov cov txheej txheem. Tab sis qhov sib txawv tau tuav txoj kev zoo rau kev saib xyuas tshwj xeeb.
