Liyini izinga le-ASTM futhi yenziwe ngani i-A36?

I-ASTM, eyaziwa ngokuthi i-American Society for Testing and Materials, iyinhlangano yamazinga enethonya emhlabeni wonke ezinikele ekuthuthukisweni nasekushicilelweni kwamazinga ezimboni ezihlukahlukene. Lawa mazinga ahlinzeka ngezindlela zokuhlola ezifanayo, imininingwane nemihlahlandlela yemboni yase-US. Lawa mazinga enzelwe ukuqinisekisa ikhwalithi, ukusebenza, nokuphepha kwemikhiqizo nezinto zokwakha kanye nokwenza lula ukusebenza kahle kohwebo lwamazwe ngamazwe.

Ukwehlukahlukana nokumbozwa kwamazinga e-ASTM kubanzi futhi kuhlanganisa imikhakha eminingi ehlanganisa, kodwa ayikhawulelwe, isayensi yezinto zokwakha, ubunjiniyela bokwakha, ikhemistri, ubunjiniyela bukagesi, nobunjiniyela bemishini.Amazinga e-ASTM ahlanganisa yonke into kusukela ekuhlolweni nasekuhlolweni kwezinto ezingavuthiwe. kuzidingo kanye nesiqondiso phakathi nokwakhiwa komkhiqizo, ukukhiqizwa, kanye nokusetshenziswa.

I-ASTM A36/A36M:

Ukucaciswa okujwayelekile kwensimbi emboza izimfuneko zensimbi yesakhiwo sekhabhoni yokwakha, ukwakhiwa, nezinye izinhlelo zokusebenza zobunjiniyela.

Ukusetshenziswa okujwayelekile kwe-ASTM A36/A36M-03a, (ilingana nekhodi ye-ASME)

Ipuleti le-A36sebenzisa
Leli zinga lisebenza kumabhuloho namabhilidi anezakhiwo ezi-riveted, eziboshiwe nezishiselwe, kanye nezigaba zensimbi yensimbi yensimbi yensimbi enenhloso evamile, amapuleti nemigoqo. Isivuno sepuleti lensimbi i-A36 cishe ngo-240MP, futhi izokhula ngokushuba kwezinto yenza inani lesivuno linciphe, ngenxa yokuqukethwe kwekhabhoni okulinganiselwe, ukusebenza okuphelele kokungcono, amandla, i-plasticity kanye ne-welding nezinye izakhiwo ukuze uthole ukufana okungcono, okusetshenziswe kakhulu.

Ukwakheka kwamakhemikhali kwepuleti lensimbi ye-A36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (lapho izinhlinzeko zensimbi equkethe ithusi).

Izakhiwo zemishini:
Amandla okukhiqiza: ≥250 .
Amandla okuqina: 400-550.
Ubude: ≥20.
Izinga likazwelonke kanye nempahla ye-A36 iyafana ne-Q235.
