ASTM A283 Letlapa la tšepe la carbon

ASTM A283 plate steel plate e na le poleiti ea tšepe ea boleng bo tlase le e mahareng e nang le matla a khabone ea boleng ba sebopeho. E na le mefuta e mene e tloaelehileng, e 'ngoe le e' ngoe e emetsoe e le thepa e arohaneng. Karolo ea thepa e ka tlase e bonts'a mefuta e kenyelletsang mefuta eohle.

Tlhaloso ena e akaretsa likarolo tse 'nè tsa lipoleiti tsa tšepe tsa carbon tsa boleng ba sebopeho bakeng sa ts'ebeliso e akaretsang. Mehlala ea tšepe e tla qhibilihisoa ka sebopi se bulehileng, sa oksijene kapa sebōpi sa motlakase. Tlhahlobo ea mocheso le sehlahisoa e tla etsoa moo lisebelisoa tsa tšepe li tla lumellana le metsoako e hlokahalang ea lik'hemik'hale tsa carbon, manganese, phosphorus, sebabole, silicon le koporo. Mehlala ea tšepe e tla boela e etse liteko tsa ho tsitsisa 'me e lumellane le litekanyetso tse hlokahalang tsa matla a ho tsitsa, ntlha ea tlhahiso, le bolelele.
