I-ASTM A449
I-ASTM A449 imboza amabhawodi anekhanda, izinduku, namabhawodi okusetshenzwa kulengwa ngobubanzi obusuka ku-1/4″ kuye ku-3″ ngokuhlanganisiwe. Kuyibhowudi yamandla aphakathi nendawo eyakhiwe ngensimbi ye-carbon emaphakathi noma i-alloy ethuthukisa amanani ayo okusebenza ngenqubo yokwelapha ukushisa. Ihloselwe izicelo zobunjiniyela ezijwayelekile.
I-ASTM A449 icishe ifane kukhemistri namandla ku-ASTM A325 kanye ne-SAE J429 grade 5. Nokho, i-A449 iguquguquka kakhudlwana ngomqondo wokuthi ihlanganisa ububanzi obukhulu bobubanzi futhi ayikhawulelwe ngokucushwa okuthile.
