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 tsim 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 ua tsaug rau kev sib koom ua ke naming Performance index tsim los ntawm AISI thiab SAE. Txhawm rau kawm paub ntau ntxiv txog cov txheej txheem npe no, nrog rau qhov sib txawv ntawm qib steel, tshuaj xyuas peb tsab xov xwm ntawm hom steel.
Thawj tus lej tsim cov chav kawm alloy ntawm cov hlau, uas yog, qhov tseem ceeb alloying Cheebtsam yog (tshwj tsis yog carbon). Nyob rau hauv cov ntaub ntawv ntawm cov hlau no, "9" qhia tau hais tias cov hlau no belongs rau cov chav kawm ntawm steels alloyed nrog silicon -manganese. 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% silicon / manganese. Thaum kawg, ob tus lej kawg sawv cev rau feem pua ntawm cov pa roj carbon hauv cov hlau, hauv 0.01% nce ntxiv. Ua raws li txoj cai no, 9260 steel muaj 0.60% 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 qhov dav dav.
Qhov feem pua ntawm cov ntsiab lus tshwj xeeb ntawm 9260 steel yog
0, 56- 0, 64% carbon
0.75-1.0% Manganese cov ntsiab lus
<= 0,035% Fósforo
1.8-2.2% silicon
<= 0,040% Azufre
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 flex nrog rau nws cov kev tiv thaiv rau 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 tempering. 9260 steel muaj qhov ntom ntom ntawm 7.85 g / cm3 (0.284 lb / hauv 3) thiab feem ntau pom muaj nyob rau hauv daim ntawv puag ncig, phaj, raj, thiab daim ntawv. Nws cov yam ntxwv zoo rau lub caij nplooj ntoos hlav ua rau 9260 steel yog qhov tshwj xeeb rau kev tsim cov nplooj thiab conical springs, tab sis nws kuj tseem siv tau rau ntau qhov chaw raws li lub zog alloy.

Kev siv ntawm 9260 steel
Hom 9260 steel yog lub caij nplooj ntoos hlav ntau yam hlau; Nws lub zog siab, corrosion kuj, hardness thiab workability ua rau nws zoo tagnrho rau txhua daim ntawv thov uas txhawb nqa resilience. Nws yog feem ntau siv rau hauv nplooj thiab conical 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
Kev siv tsheb ciav hlau
thiab ntau dua.
9260 steel yog yooj yim los ntawm, yog li tsis txhob yig nug koj tus neeg muag khoom txog cov hlau zoo nkauj no yog tias koj pom tias nws 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 rau cov hlau twg los siv hauv koj cov qauv tsim.
