Letlapa la tšepe la ASTM A36

Ho ipapisitsoe le bongata ba khabone e teng ka har'a motsoako. Litšepe tse tlase tsa khabone li bonolo ebile li theha habonolo, 'me litšepe tse nang le khabone e phahameng li thata ebile li matla, empa li fokola haholo,' me li thatafalloa haholo ke mochini le ho cheselletsa. Ka tlase ke thepa ea likarolo tsa carbon steel tseo re fanang ka tsona:
● Khabone e Tlase–Moetso oa 0.05% -0.25% oa carbon le ho fihla ho 0.4% manganese. E boetse e tsejoa e le mild steel, ke thepa e theko e tlaase eo ho leng bonolo ho e bōpa. Le hoja e se thata joaloka litšepe tse phahameng tsa carbon, ho pata koloi ho ka eketsa boima ba eona bo holimo.
● Bohareng ba Carbon Steel - Sebopeho sa 0.29% -0.54% carbon, e nang le 0.60% -1.65% manganese. Medium carbon steel e na le ductile ebile e matla, e nang le thepa ea nako e telele.
● Motsoako o Phahameng oa Carbon Steel– Motsoako oa 0.55% -0.95% carbon, o nang le 0.30% -0.90% manganese. E matla haholo 'me e tšoara mohopolo oa sebopeho hantle, e etsa hore e be e loketseng bakeng sa liliba le terata.
● Khabone e Phahameng haholo - Motsoako oa 0.96% -2.1% oa carbon. Likahare tsa eona tse phahameng tsa khabone li etsa hore e be thepa e matla haholo. Ka lebaka la brittleness ea eona, sehlopha sena se hloka ho tšoaroa ka mokhoa o khethehileng.
