** 1.Dab tsi yog 1018 steel siv rau?**
1018 steel yog tsawg- carbon steel paub txog nws cov weldability zoo thiab zoo ductility. Nws yog feem ntau siv rau qhov chaw uas yuav tsum tau ua kom txias, xws li khoov, crimping, lossis swaging. Cov ntawv thov xws li shafts, pins, spindles, rods, thiab ntau yam khoom siv tshuab uas tsis xav tau lub zog siab. Nws kuj yog siv dav rau kev tsim cov phiaj xwm dav dav.
**2.Qhov twg yog qhov nyuaj, 1018 lossis 4140 steel?**
Nyob rau hauv lawv cov feem ntau "raws li{0}}muab" tej yam kev mob (xws li, txias dov rau 1018 thiab annealed rau 4140), 4140 steel yog ho nyuaj tshaj li 1018 steel . 4140 yog ib tug chromium- molybdenum alloy hlau uas yuav tsum tau tshav kub kho kom ua tau zoo heev theem ntawm hardness thiab ntau npaum li cas. qis- carbon 1018 steel.
**3.Dab tsi yog 4140 steel siv rau?**
4140 steel yog ntau yam, siab - lub zog alloy steel siv nyob rau hauv daim ntawv thov uas yuav tsum tau zoo toughness, qaug zog, thiab hnav tsis kam. Nws feem ntau yog cua sov- kho kom txhim kho cov khoom no. Koj yuav pom nws siv rau axles, bolts, txuas rods, gears, spindles, laum dab tshos, thiab lwm yam tseem ceeb yam ntxwv Cheebtsam nyob rau hauv lub tsheb, aerospace, thiab roj thiab roj industries.
** 4.Cas 1018 steel yuav kub dov?**
Yog lawm, 1018 steel yog feem ntau nkag rau hauv qhov kub -khoov mob. Kub- dov 1018 steel muaj qhov ntxhib, ntsuas qhov chaw thiab tsis tshua muaj meej hauv nws qhov ntev dua li txias -rolled 1018, tab sis nws yog kev lag luam ntau dua thiab zoo kawg nkaus haum rau ntau daim ntawv thov qhov chaw ua tiav thiab nruj tolerances tsis tseem ceeb.
** 5.Can 4140 steel bent?**
Yog lawm, 4140 steel tuaj yeem khoov tau, tab sis nws txoj kev khoov tau nyob ntawm nws qhov mob. Nyob rau hauv lub xeev annealed, 4140 yog qhov muag muag thiab ductile, ua rau nws zoo heev rau kev ua haujlwm dabtsi yog khoov. Txawm li cas los xij, yog tias nws tau raug cua sov- kho kom muaj zog siab (hardened thiab tempered), nws yuav nyuaj heev rau khoov thiab yuav tawg. Txhawm rau khoov tau zoo, 4140 feem ntau yog khoov rau hauv nws lub xeev annealed thiab tom qab ntawd cua sov- kho tom qab kom ua tiav lub zog xav tau.
