Mechanical Properties Sib piv
| Khoom | 50 Mn | ua 71mn | Kev ua haujlwm cuam tshuam rau Rail Track |
|---|---|---|---|
| Yield zog (MPa) | ~ 370-400 MPa | Ntau dua lossis sib npaug rau 390 MPa (Ntau dua lossis sib npaug rau 40 kg / mm²) | U71Mn muab kev tiv thaiv zoo tshaj plaws tiv thaiv cov yas deformation nyob rau hauv hnyav static thiab dynamic loads. |
| Tensile zog (Rm) | Ntau dua lossis sib npaug li 645 MPa | Ntau dua lossis sib npaug li 880 MPa | U71Mn ua qauv qhia ntau dua 36% siab dua qhov kawg ntawm lub peev xwm, tiv thaiv kev khoov deformation thiab kev sib koom ua haujlwm tsis ua haujlwm. |
| Elongation (A5%) | Ntau dua lossis sib npaug li 13% | Ntau dua lossis sib npaug li 9% | 50Mn muaj peev xwm ntau dua cov yas deformation, ua rau nws zam ntau dua thaum khoov txias lossis thermal expansion stress. |
| Hardness (HBW) | 200–240 HWB | 260-300 HWB | U71Mn qhov siab ntawm qhov tawv tawv ua rau ncua kev tsheb ciav hlau lub taub hau, sab abrasion, thiab hlau flaking. |
