1. Lub zog tensile (ASTM A242 Corten a)
| Ntiag tug | Qhov toob kas(Imperial) | Qhov toob kas(Metric) |
|---|---|---|
| Tensile lub zog (min) | 70 ksi(kilopound ib sq. Hauv.) | 485 MPa(MegapScal) |
| Yield zog (min) | 50 ksi | 345 MPa |
| Elongation (min) | 18%(hauv 8 ") | 18%(hauv 200 hli) |

2. Kev sib piv nrog lwm cov huab cua
| Teem nqi | Tensile (MPA) | Tawm los (MPA) | Elongation (%) |
|---|---|---|---|
| Corten A (A242) | 485 min | 345 min | 18 feeb |
| Corten B (A588) | 485 min | 345 min | 18 feeb |
| S355j2w (en) | 470-630 | 355 min | 20 feeb |
Corten muajLub zog zoo sib xws rau Corten B (A588)Tab sis sib txawv nyob rau hauv Alloy muaj pes tsawg leeg (siab duaPhosphorusRau kev tsim zoo patina zoo dua).
3. Kev cuam tshuam ntawm Vuam & Fabrication
High tensile lub zogtxhais tau tias nws tuaj yeem cojCov Txheej Txheem Txheej TxheemTab sis xav tauPreheating (100-150 degree)rau vuam.
Tsawg elongation (vs. hlau me)txhais tau tias nws tsawg dua ductile-zam rau kev kub dhau mus.
4. Cov ntawv thov tseem ceeb uas siv cov khoom no
Txuas hniav & kev loj(Xav tau cov txiaj ntsig zoo lub zog rau cov ris nra).
