Khoom Parameters
Carbon Steel: Khoom, Ntau lawm, Piv txwv thiab kev siv
Carbon steel yog hlau - carbon alloy, uas muaj txog li 2.1 wt.% carbon. Rau cov pa roj carbon steel, tsis muaj qhov tsawg kawg nkaus cov ntsiab lus ntawm lwm cov hlau alloying, txawm li cas los xij, lawv feem ntau muaj manganese. Qhov siab tshaj plaws manganese, silicon thiab tooj liab cov ntsiab lus yuav tsum tsawg dua 1.65 wt.%, 0.6 wt.% thiab 0.6 wt.%, feem.
Hom carbon steel thiab lawv cov khoom
Cov pa roj carbon steel tuaj yeem muab faib ua peb pawg raws li nws cov ntsiab lus carbon: qis- carbon steel (los yog me me- carbon steel), nruab nrab - carbon steel thiab siab - carbon steel . Lawv cov ntsiab lus carbon, microstructure thiab cov khoom sib piv raws li hauv qab no:
| Cov ntsiab lus carbon (wt.%) | Microstructure | Cov khoom | Piv txwv |
| Tsawg- carbon steel | < 0.25 | Ferrite, pearlite | Tsawg hardness thiab nqi. High ductility, toughness, machinability thiab weldability |
| Nruab nrab- carbon steel | 0.25 – 0.60 | Martensite | Tsawg hardenability, nruab nrab lub zog, ductility thiab toughness |
| Siab - carbon steel | 0.60 – 1.25 | Pearlite | High hardness, lub zog, tsawg ductility |
