Kab lus no qhia txog 9260 steel, lub siab silicon alloy caij nplooj ntoos hlav hlau paub txog nws cov yam ntxwv ua haujlwm zoo. Los ntawm kev piav qhia txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev siv ntawm 9260 steel, kab lus no yog npaj los pab cov neeg nyeem txiav txim siab tias 9260 steel yog ib qho khoom siv zoo rau lawv qhov project.
Lub cev muaj zog ntawm 9260 Steel
9260 steel tau txais nws lub npe plaub tus lej los ntawm kev sib koom ua ke naming Performance index tsim los ntawm AISI thiab SAE. Yog xav paub ntxiv txog cov txheej txheem npe no, nrog rau qhov sib txawv ntawm cov qib steel, mus saib peb tsab xov xwm ntawm hom steels.
Thawj tus lej tsim cov chav kawm alloy ntawm cov hlau, uas yog, cov ntsiab lus alloying yog dab tsi (tshwj tsis yog cov pa roj carbon). Nyob rau hauv cov ntaub ntawv ntawm cov hlau no, "9" qhia tias cov hlau no belongs rau cov chav kawm ntawm silicon-manganese alloy steels. Tus lej thib ob sawv cev rau feem pua ntawm cov ntsiab lus tseem ceeb no; cov "2" nyob rau hauv 9260 steel yog li ntawd txhais tau hais tias cov chav kawm no yog nyob ib ncig ntawm 2 feem pua silicon/manganese. Thaum kawg, ob tus lej kawg sawv cev rau feem pua ntawm cov pa roj carbon hauv cov hlau, hauv kev nce ntxiv ntawm 0.01 feem pua. Ua raws li txoj cai no, 9260 steel muaj 0.60 feem pua carbon. Cov tshuaj muaj pes tsawg leeg ntawm 9260 steel yog ntau qhov tshwj xeeb (saib hauv qab no rau kev ua siab ntev), tab sis nws lub npe muab lub tswv yim zoo ntawm nws cov ntsiab lus dav dav.
Qhov feem pua ntawm cov ntsiab lus tshwj xeeb ntawm 9260 steel yog
0,56- 0,64 feem pua Carbon

9260 steel feem ntau tuaj yeem pom raws li AISI 9260 steel thiab suav tias yog lub siab silicon alloy caij nplooj ntoos hlav hlau. Qhov no txhais tau hais tias nws muaj cov yam ntxwv zoo caij nplooj ntoos hlav thiab muaj txiaj ntsig zoo rau nws cov flexing nrog rau nws tsis kam mus deformation. Nws yog yooj yim machined thaum annealed thiab tuaj yeem welded los ntawm txhua txoj kev tsuas yog oxyacetylene torches. Feem ntau, nws yog corrosion resistant thiab yog ib qho nyuaj txaus los tiv thaiv lub zos deformation. Nws yog forgeable thiab kub kho tau thiab teb zoo rau quenching. 9260 steel muaj qhov ntom ntom ntawm 7.85 g / cm3 (0.284 lb / hauv 3) thiab feem ntau pom muaj nyob rau hauv round bar, phaj, raj, thiab daim ntawv. Nws cov yam ntxwv zoo heev ntawm lub caij nplooj ntoos hlav ua rau 9260 qhov kev xaiv tshwj xeeb rau kev tsim cov nplooj thiab lub khob hliav qab, tab sis nws kuj tuaj yeem siv rau ntau qhov chaw raws li lub zog muaj zog alloy.

Kev siv ntawm 9260 steel
Hom 9260 steel yog lub caij nplooj ntoos hlav ntau yam hlau; nws cov kev ua haujlwm siab, tsis kam tiv thaiv corrosion, hardness thiab workability ua rau nws zoo tagnrho rau txhua daim ntawv thov uas nyiam cov resilience. Nws feem ntau yog siv rau hauv nplooj thiab taper springs, tab sis lwm yam kev siv tseem ceeb tuaj yeem pom hauv qab no:
aircraft qhov chaw
tub rog technology
choj txhawb
Cov cuab yeej siv tshuab
cov hniav thiab cov hniav
railway applications
thiab ntau dua.
9260 steel yog npaj tau, yog li tsis txhob yig nug koj tus neeg muag khoom txog cov hlau zoo nkauj no yog tias nws zoo li muaj txiaj ntsig rau koj qhov project. Lawv yuav muab cov ntaub ntawv tseem ceeb rau koj nrog rau lwm txoj hauv kev thiab muab lub tswv yim zoo tshaj plaws ntawm cov hlau twg los siv hauv koj cov qauv tsim.
