Tshuaj muaj pes tsawg leeg
A36 yog cov pa roj carbon tsawg hlau . Tsawg carbon hlau yog cais los ntawm muaj tsawg dua 0.3% carbon los ntawm qhov hnyav. Qhov no tso cai A36 hlau kom tau yooj yim machined, welded, thiab tsim, ua rau nws tsis tshua muaj txiaj ntsig zoo li lub hom phiaj dav dav hlau
Ntawm no, dab tsi yog a36 steel sib npaug?
ASTM A36 paub tias yog sib npaug rau EN S275 hlau phaj. A36 (Yield zog min. 250Mpa, tensile lub zog ntawm 400-550Mpa) yog ib qho feem ntau carbon structural hlau qib, sib npaug EN 10025-2 S235JR, tsis yog S275JR hlau muaj lub zog tensile siab dua thiab tawm dag zog ntau dua li ASTM A36.
Kuj Paub, qhov txawv ntawm a36 thiab a572 steel yog dab tsi? Hauv paus A572 yog lub zog siab, qis alloy Columbium-Vanadium structural hlau . A514 kuj tseem muaj zog hlau feem ntau yog siv rau kev tsim vaj tsev. A36 tsuas yog ib qho qis carbonsteel siv hauv bolted, riveted thiab welded txheej txheem. Nyob ntawm koj daim ntawv thov, txawv hlau cov qib yuav siv tau.
Ntawm no, qhov a hauv a36 steel txhais li cas?
ASTM A36 phaj yog qis carbon hlau uas qhia tau zoo zog ua ke nrog formability. Nws yog yooj yim rau tshuab thiab fabricate thiab tuaj yeem ruaj ntseg welded. A36 yog ib qho kev tsim qauv hlau phaj uas tuaj yeem galvanized los muab kev tiv thaiv corrosion ntxiv.
Lub hardness ntawm a36 steel yog dab tsi?
| Lub cev muaj zog | Metric | Lus Askiv |
|---|---|---|
| Hardness, Brinell | 119 - 159 | 119 - 159 |
| Hardness, Rockwell B | 67 - 83 | 67 - 83 |
| Tensile Strength ntawm Break | 400-552 MPa | 58000-80000 psi |
| Tensile zog, tawm los | > = 248 MPa | > = 36000 psi |
