ASTM A36ua raws li cov qauv ntawm American Society for Testing and Materials, thiab cov pa roj carbon zoo tib yam cov kav dej ua tau raws li ASME cov qauv yog sib npaug rau Tuam Tshoj cov khoom siv Q235, uas belongs rau American Standard thiab Common carbon steel phaj.

ASTM A36 yog tsim rau riveting, bolting thiab vuam cov qauv siv nyob rau hauv cov choj thiab cov tsev, thiab feem ntau yog siv nyob rau hauv machinery manufacturing. ASTM A36 muaj kev txiav thiab vuam zoo. Nyob rau hauv cov nqe lus ntawm kev txiav, nws muaj kev ruaj ntseg kev ua tau zoo, me me txiav deformation thiab yooj yim rau weld. Nws yog dav siv nyob rau hauv manufacturing industries xws li hnyav khoom spare qhov chaw manufacturing, metallurgy thiab tshuaj kev lag luam, thiab flanges.

ASTM A36 Cov Qauv Txheej Txheem: ASTM A36 / A36M-03a.
Cov ntsiab lus tshuaj thiab muaj pes tsawg leeg ntawm ASTM A36:

1. Khoom: C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), Cu (tooj liab)
2. Muaj pes tsawg leeg: C: ≤0.25, Si≤0.40, Mn: ≤0.80-1.20, P≤0.04, S: ≤0.05, Cu≥0.20. (nyob rau hauv cov ntaub ntawv ntawm tooj liab-muaj steel)

ASTM A36 cov kev cai: kev kuaj pom qhov tsis zoo, Z15Z35 thickness kev taw qhia kev ua tau zoo, siab zog, siab toughness thiab lwm yam yuav tsum tau ua.

Cov yam ntxwv ntawm ASTM A36:
Yield zog —— ≥250MPa
Tensile zog - 400MPa-550MPa
Elongation tom qab so - ≥20% (tsis muaj kev cuam tshuam)

Kev xa khoom ntawm ASTM A36:
Tsis muaj qhov tsis xws luag xws li tawg, npuas, thiab nti ntawm qhov chaw. Cov txheej txheem xa khoom ntawm cov phaj hlau yog kub-dov, thiab nws tuaj yeem xa tau raws li kev xav tau xws li normalizing, tempering, thiab tswj dov; Kev kuaj pom qhov tsis haum tuaj yeem ua tau raws li 1 sojntsuam, 2 sojntsuam, thiab 3 sojntsuam; Thickness extension yuav ua tau z15, z25, z35.
