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.

Ukwahluka kunye nokugutyungelwa kwemigangatho ye-ASTM kubanzi kwaye kugubungela uluhlu olubanzi lwemimandla ebandakanya, kodwa ingaphelelanga apho, isayensi yezinto, ubunjineli bokwakha, ikhemistri, ubunjineli bombane, kunye nobunjineli bomatshini.Imigangatho yeASTM igubungela yonke into ukusuka kuvavanyo kunye novavanyo lwezinto ezikrwada kwiimfuno kunye nesikhokelo ngexesha loyilo lwemveliso, ukuveliswa 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, ibhoti kunye nezakhiwo ezidityanisiweyo, kunye neenjongo eziqhelekileyo zolwakhiwo lwamacandelo entsimbi yentsimbi yentsimbi, iipleyiti kunye nemivalo.A36 ipleyiti yentsimbi isivuno malunga ne-240MP, kwaye iya kwandisa kunye nobukhulu bezinto ukwenza ixabiso lemveliso liyancipha, ngenxa yemodareyitha yekhabhoni, umgangatho wekhabhoni ungcono, sifumana umgangatho ongcono wekhabhoni, sifumana amandla angcono kunye nomgangatho weplastiki, ukusebenza kakuhle kunye nezinye iimpawu zeplastiki. eyona isetyenziswa 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.
