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

I-ASTM, eyaziwa ngokuba yi-American Society for Testing and Materials, ngumbutho wemigangatho onempembelelo kumazwe ngamazwe ozinikele ekuphuhliseni nasekupapasheni imigangatho kumashishini ahlukeneyo. Le migangatho ibonelela ngeendlela zovavanyo ezifanayo, iinkcukacha kunye nezikhokelo kushishino lwase-US. Le migangatho yenzelwe ukuqinisekisa umgangatho, ukusebenza, kunye nokhuseleko lweemveliso kunye nezixhobo kunye nokuququzelela ukusebenza kakuhle korhwebo lwamazwe ngamazwe.

Iyantlukwano kunye nokugutyungelwa kwemigangatho ye-ASTM kubanzi kwaye igubungela uluhlu olubanzi lwemimandla ebandakanya, kodwa ingaphelelanga apho, isayensi yezixhobo, ubunjineli bokwakha, ikhemistri, ubunjineli bombane, kunye nobunjineli bomatshini.Imigangatho yeASTM igubungela yonke into ukusuka kuvavanyo kunye novavanyo lwemathiriyeli ekrwada. kwiimfuno kunye nesikhokelo ngexesha loyilo lwemveliso, imveliso, kunye nokusetyenziswa.

I-ASTM A36/A36M:

Inkcazo esemgangathweni yentsimbi egubungela iimfuno zentsimbi yesakhiwo sekhabhoni yokwakha, ukuveliswa, kunye nezinye izicelo zobunjineli.

Ipleyiti yentsimbi ye-A36IMigangatho yokuNyanzeliswa
Ukwenziwa komgangatho we-ASTM A36/A36M-03a, (ilingana nekhowudi ye-ASME)

Ipleyiti ye-A36sebenzisa
Lo mgangatho usebenza kwiibhulorho kunye nezakhiwo ezine-riveted, i-bolted kunye nezakhiwo ezidityanisiweyo, kunye neenjongo eziqhelekileyo zesakhiwo sentsimbi ye-carbon steel, iipleyiti kunye nemivalo. yenza ixabiso lesivuno liyancipha, ngenxa yomxholo wekhabhoni ophakathi, ukusebenza ngokubanzi kokungcono, amandla, iplastiki kunye ne-welding kunye nezinye iipropati zokufumana umdlalo ongcono, osetyenziswa kakhulu.

Ukwakheka kweekhemikhali zentsimbi yentsimbi ye-A36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (xa izibonelelo zetsimbi ezinobhedu).

Iimpawu zoomatshini:
Amandla esivuno: ≥250.
Amandla okuqina: 400-550.
Ubude: ≥20.
Umgangatho wesizwe kunye nezinto ze-A36 ziyafana ne-Q235.
