Khoom Description
Txias dov steel phaj plays lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas xav tau qhov zoo ntawm qhov chaw, nruj qhov ntev ntev, thiab kev ua haujlwm ruaj khov. Ntawm cov feem ntau siv txias dov steel qib,DC01, DC03, DC04, DC05, DC06, thiab DC07txhais hauv qabTS EN 10130feem ntau yog xaiv rau cov ntawv thov xws li los ntawm cov qauv txheej txheem mus rau kev sib sib zog nqus- kos duab qhov chaw.
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.
Cold dov hlau
Cold Rolled Steel Phaj yog dab tsi?
Txias dov steel phaj yog tsim los ntawm kev ua kom kub dov hlau los ntawm kev txo qis hauv chav sov. Cov txheej txheem no txhim kho qhov chaw tiav, thickness raug, thiab txhua yam sib xws. Piv nrog rau cov kub dov hlau, cov qib txias dov muab cov npoo smoother, zoo dua flatness, thiab txhim kho formability, ua rau lawv zoo tagnrho rau precision stamping, dabtsi yog khoov, thiab kev ua haujlwm.
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 |
