Kodi muyezo wa ASTM ndi chiyani ndipo A36 imapangidwa ndi chiyani?

ASTM, yomwe imadziwika kuti American Society for Testing and Equipment, ndi bungwe lotsogola padziko lonse lapansi lodzipereka pakupanga ndi kufalitsa miyezo yamafakitale osiyanasiyana. Miyezo iyi imapereka njira zoyesera zofananira, zofotokozera ndi malangizo pamakampani aku US. Miyezoyi idapangidwa kuti iwonetsetse kuti zabwino, magwiridwe antchito, ndi chitetezo chazinthu ndi zida ndikuthandizira kuyendetsa bwino kwa malonda apadziko lonse lapansi.

Kusiyanasiyana ndi kufalikira kwa miyezo ya ASTM ndikokulirapo ndipo kumakhudza magawo osiyanasiyana kuphatikiza, koma osawerengeka, sayansi yazinthu, zomangamanga, chemistry, uinjiniya wamagetsi, ndi uinjiniya wamakina.Miyezo ya ASTM imakhudza chilichonse kuyambira pakuyesa ndi kuwunika kwazinthu zopangira mpaka pazofunikira ndi chitsogozo pakupanga, kupanga, ndi kugwiritsa ntchito.

ASTM A36/A36M:

Mafotokozedwe okhazikika achitsulo omwe amaphimba zofunikira pakupanga chitsulo cha carbon pomanga, kupanga, ndi ntchito zina zauinjiniya.

Chipinda chachitsulo cha A36Miyezo Yoyendetsera Ntchito
Muyezo woyeserera wa ASTM A36/A36M-03a, (wofanana ndi ASME code)

A36 mbalentchito
Muyezo uwu umakhudza milatho ndi nyumba ndi nyumba riveted, bolted ndi welded, komanso ambiri cholinga structural zitsulo khalidwe zigawo carbon zitsulo, mbale ndi mipiringidzo. omwe amagwiritsidwa ntchito kwambiri.

A36 zitsulo mbale mankhwala zikuchokera:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0,20 (pamene zoperekedwa ndi zitsulo zamkuwa).

Makaniko katundu:
Mphamvu zokolola: ≥250 .
Mphamvu yolimba: 400-550.
Kutalika: ≥20.
Muyezo wadziko lonse ndi zinthu za A36 ndizofanana ndi Q235.
