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 lehle, ngenxa yokuqukethwe kwekhabhoni okusesilinganisweni, ukusebenza okuphelele kokungcono, amandla, ipulasitiki kanye nokushisela nezinye izakhiwo ukuze uthole ukufana okungcono, esetshenziswa 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.
