Chii chinonzi ASTM chiyero uye chii chinonzi A36 yakagadzirwa?

ASTM, inozivikanwa seAmerican Society for Testing and Materials, isangano repasi rose rine simba rezviyero rakatsaurirwa mukusimudzira uye kushambadza zviyero zvemaindasitiri akasiyana. Aya mazinga anopa yunifomu yekuyedza nzira, zvirevo uye nhungamiro yeindasitiri yeUS. Aya mazinga akagadzirirwa kuve nechokwadi chemhando, kuita, uye kuchengetedzeka kwezvigadzirwa uye zvigadzirwa uye kufambisa kushanda zvakanaka kwekutengeserana kwenyika.

Kusiyana uye kufukidzwa kwemazinga eASTM kwakakura uye kunobata nzvimbo dzakasiyana siyana dzinosanganisira, asi dzisina kuganhurirwa, sainzi yezvekushandisa, engineering yekuvaka, chemistry, engineering yemagetsi, uye mechanical engineering.ASTM zviyero zvinofukidza zvese kubva pakuedzwa uye kuongororwa kwezvakagadzirwa kusvika kune zvinodiwa uye kutungamira panguva yekugadzirwa kwechigadzirwa, kugadzira uye kushandiswa.

ASTM A36/A36M:

Yakajairwa simbi inovhara zvinodikanwa zvekuumbwa kabhoni simbi yekuvaka, kugadzira, uye mamwe mainjiniya ekushandisa.

A36 Steel PlateMitemo Yekusimbisa
Execution standard ASTM A36/A36M-03a, (yakaenzana neASME kodhi)

A36 ndirouse
Iyi chiyero inoshanda kune mabhiriji uye zvivakwa zvine riveted, mabhaudhi uye welded zvimiro, pamwe neakawanda-chinangwa chechimiro chesimbi kabhoni simbi zvikamu, mahwendefa uye mabara. inonyanya kushandiswa.

A36 simbi ndiro kemikari yakagadzirwa:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (apo zvigadziro zvemhangura-ine simbi).

Mechanical properties:
Goho simba: ≥250 .
Tensile simba: 400-550.
Elongation: ≥20.
National standard uye A36 zvinhu zvakafanana neQ235.
