SAE4130 SAE4140 Mechanical Precision Steel Tubes
Ntsiab nta
SAE4130 thiab SAE4140 yog qib qis- alloy steel qib uas tau siv dav hauv kev tsim cov tshuab precision steel raj. Cov qhab nia no paub txog lawv lub zog zoo, toughness, thiab hnav tsis kam, ua rau lawv haum rau ntau yam kev thov. Cov raj precision ua los ntawm cov hlau no yog cov yam ntxwv ntawm lawv qhov siab qhov tseeb, du nto tiav, thiab cov khoom siv kho kom zoo ib yam.
SAE4130 yog chromium-molybdenum alloy steel nrog zoo weldability thiab machinability. Nws yog feem ntau siv nyob rau hauv daim ntawv thov uas siab zog thiab toughness yuav tsum tau. SAE4140, ntawm qhov tod tes, muaj cov ntsiab lus carbon ntau dua SAE4130, muab kev txhim kho hardness thiab lub zog. Ob qib yog cua sov- kho tau, tso cai rau kev txhim kho ntxiv ntawm lawv cov khoom siv kho tshuab.
