Iyini indinganiso ye-ASTM futhi yenziwe ngani i-A36?

I-ASTM, eyaziwa ngokuthi i-American Society for Testing and Materials, iyinhlangano yezindinganiso enethonya emhlabeni wonke ezinikele ekuthuthukiseni nasekushicilelweni kwezindinganiso zezimboni ezahlukene. Lezi zindinganiso zinikeza izindlela zokuhlola ezifanayo, imininingwane kanye neziqondiso zemboni yase-US. Lezi zindinganiso zenzelwe ukuqinisekisa ikhwalithi, ukusebenza, kanye nokuphepha kwemikhiqizo nezinto zokwakha kanye nokwenza kube lula ukusebenza kahle kokuhweba kwamazwe ngamazwe.

Ukuhlukahluka kanye nokumbozwa kwezindinganiso ze-ASTM kubanzi futhi kuhlanganisa imikhakha eminingi ehlanganisa, kodwa kungagcini lapho, isayensi yezinto zokwakha, ubunjiniyela bokwakha, ikhemistri, ubunjiniyela kagesi, kanye nobunjiniyela bemishini. Izindinganiso ze-ASTM zihlanganisa konke kusukela ekuhlolweni nasekuhlolweni kwezinto zokusetshenziswa kuya ezidingweni kanye nesiqondiso ngesikhathi sokuklama umkhiqizo, ukukhiqizwa, kanye nokusetshenziswa kwawo.

I-ASTM A36/A36M:

Imininingwane ejwayelekile yensimbi ehlanganisa izidingo zensimbi yekhabhoni yokwakha, yokwenziwa, nezinye izinhlelo zokusebenza zobunjiniyela.

Ipuleti Lensimbi le-A36Izindinganiso Zokuphoqelela
Izinga lokusebenza le-ASTM A36/A36M-03a, (elilingana nekhodi ye-ASME)

Ipuleti le-A36sebenzisa
Leli zinga lisebenza kumabhuloho nezakhiwo ezinezakhiwo ezigobile, eziboshwe futhi ezishiselwe, kanye nezingxenye zensimbi yekhabhoni zekhwalithi yesakhiwo esijwayelekile, amapuleti kanye nemigoqo. Ipuleti lensimbi le-A36 likhiqiza cishe ku-240MP, futhi lizokhula ngokujiya kwezinto ukuze lenze inani lesivuno lehle, ngenxa yokuqukethwe kwekhabhoni okumaphakathi, ukusebenza okuphelele okungcono, amandla, i-plasticity kanye ne-welding kanye nezinye izakhiwo ukuze kutholakale ukufana okungcono, okusetshenziswa kakhulu.

Ukwakheka kwamakhemikhali epuleti lensimbi le-A36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (lapho kunikezwa khona insimbi equkethe ithusi).

Izakhiwo zemishini:
Amandla okukhiqiza: ≥250.
Amandla okunamathela: 400-550.
Ukwelulwa: ≥20.
Izinga likazwelonke kanye nezinto ze-A36 zifana ne-Q235.
