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 komanso kufalikira kwa miyezo ya ASTM ndi yayikulu ndipo imakhudza magawo osiyanasiyana kuphatikiza, koma osalekezera, sayansi yazinthu, zomangamanga, chemistry, uinjiniya wamagetsi, ndi uinjiniya wamakina. Miyezo ya ASTM imakhudza chilichonse kuyambira pakuyesa ndikuwunika kwazinthu zopangira ku zofunikira 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.

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

A36 mbalentchito
Izi zikugwiranso ntchito ku milatho ndi nyumba zokhala ndi zida zokhometsedwa, zokhometsedwa komanso zomata, komanso zigawo zopangira zitsulo zopangidwa ndi chitsulo, mbale ndi mipiringidzo. kupanga zokolola mtengo amachepetsa, chifukwa cha zolimbitsa mpweya zili, ntchito wonse wa bwino, mphamvu, pulasitiki ndi kuwotcherera ndi katundu zina kupeza machesi bwino, ambiri ankagwiritsa ntchito.

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.
