Yintoni umgangatho we-ASTM kwaye yenziwe ngantoni i-A36?

I-ASTM, eyaziwa ngokuba yi-American Society for Testing and Materials, yintlangano yemigangatho enefuthe kwihlabathi liphela ezinikele ekuphuhlisweni nasekupapashweni kwemigangatho yamashishini ahlukeneyo. Le migangatho ibonelela ngeendlela zovavanyo ezifanayo, iinkcukacha kunye nezikhokelo kushishino lwaseMelika. Le migangatho yenzelwe ukuqinisekisa umgangatho, ukusebenza, kunye nokhuseleko lweemveliso kunye nezixhobo kunye nokwenza kube lula ukusebenza kakuhle korhwebo lwamazwe ngamazwe.

Ukwahlukahluka kunye nokugutyungelwa kwemigangatho ye-ASTM kubanzi kwaye kugubungela uluhlu olubanzi lweendawo eziquka, kodwa kungaphelelanga apho, isayensi yezinto, ubunjineli bokwakha, ikhemistri, ubunjineli bombane, kunye nobunjineli boomatshini. Imigangatho ye-ASTM igubungela yonke into ukusuka kuvavanyo kunye novavanyo lwezinto eziluhlaza ukuya kwiimfuno kunye nesikhokelo ngexesha loyilo lwemveliso, imveliso, kunye nokusetyenziswa.

I-ASTM A36/A36M:

Inkcazo eqhelekileyo yentsimbi egubungela iimfuno zentsimbi yekhabhoni yokwakha, ukwenziwa, kunye nezinye izicelo zobunjineli.

Ipleyiti yentsimbi ye-A36Imigangatho yokuQinisekisa
Umgangatho wokusebenza we-ASTM A36/A36M-03a, (olingana nekhowudi ye-ASME)

Ipleyiti ye-A36sebenzisa
Lo mgangatho usebenza kwiibhulorho kunye nezakhiwo ezinezakhiwo ezigobileyo, ezibotshelelweyo nezidibeneyo, kunye neendawo zentsimbi yekhabhoni ezisemgangathweni, iipleyiti kunye neebhari. Ipleyiti yentsimbi ye-A36 ivelisa malunga ne-240MP, kwaye iya kwanda ngokutyeba kwezinto ukuze ixabiso lemveliso lehle, ngenxa yomxholo wekhabhoni ophakathi, ukusebenza kwayo ngcono, amandla, i-plasticity kunye ne-welding kunye nezinye iimpawu zokufumana umdlalo ongcono, eyona isetyenziswa kakhulu.

Ulwakhiwo lweekhemikhali zepleyiti yentsimbi ye-A36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (xa amalungiselelo entsimbi equlethe ubhedu).

Iimpawu zoomatshini:
Amandla okuvelisa: ≥250.
Amandla okutsalwa: 400-550.
Ukwandiswa: ≥20.
Izinto ezisemgangathweni kazwelonke kunye ne-A36 ziyafana ne-Q235.
