A36 yog cov pa roj carbon tsawg. Cov pa roj carbon tsawg yog cais los ntawm qhov muaj tsawg dua 0.3% carbon los ntawm qhov hnyav. Qhov no tso cai rau A36 steel tau yooj yim machined, welded, thiab tsim, ua rau nws tsis tshua muaj txiaj ntsig zoo li cov hlau dav dav. Cov pa roj carbon tsawg kuj tiv thaiv kev kho cua sov los ntawm kev cuam tshuam ntau ntawm A36 steel. A36 steel feem ntau muaj me me ntawm lwm cov hlau alloying zoo li, suav nrog manganese, sulfur, phosphorus, thiab silicon. Cov ntsiab lus alloying no tau ntxiv los muab A36 steel nws xav tau tshuaj thiab cov khoom siv kho tshuab. Txij li thaum A36 tsis muaj ntau cov npib tsib xee lossis chromium, nws tsis muaj corrosion kuj zoo heev.
Tsis zoo li feem ntau AISI qib xws li 1018, 1141, lossis 4140, American Society for Testing and Materials (ASTM) A36 steel tsis raug xaiv los ntawm cov tshuaj muaj pes tsawg leeg. Hloov chaw, A36 yog tsim los ntawm cov khoom siv kho tshuab. Qhov no txhais tau hais tias thaum feem ntau cov qhab nia yuav tsum tau ntxiv cov alloys uas haum ntawm qee feem pua, A36 yuav tsum ua tau raws li cov qauv siv tshuab tshwj xeeb. Piv txwv li, steel tuav thiab daim hlau yuav tsum muaj qhov tsawg kawg nkaus yield zog ntawm 36, 000 phaus ib square inch. Txawm hais tias muaj qee qhov kev xav tau ntawm cov tshuaj lom neeg uas yuav tsum tau ua raws li A36 steel, cov yam ntxwv tseem ceeb tshaj plaws yog qhov yuav tsum tau muaj zog yield.
A36 yog tsim nyob rau hauv ib tug zam zoo li feem ntau carbon steels. Ua ntej, hlau ore thiab thee tau muab tso rau hauv lub qhov cub. Cov impurities raug hlawv tawm thiab cov ntsiab lus alloying ntxiv rau cov hlau molten. Thaum cov tshuaj muaj pes tsawg leeg ntawm A36 steel tiav, nws yog solidified nyob rau hauv ib tug rectangular ingot. A36 steel feem ntau yog kub dov. Qhov no txhais tau hais tias nws yog tsim rau nws qhov kawg qhov ntev hauv kev siv cov yob thaum lub ingot nyob rau ntawm qhov kub siab.
