5140 Hlau: Khoom thiab Daim Ntawv Thov

 

5140 steel yog ib qho nruab nrab carbon, chromium alloy steel paub txog nws cov khoom siv kho tshuab zoo heev thiab kev siv ntau yam. Cov hlau no tau siv dav hauv ntau qhov kev lag luam vim nws qhov sib xyaw ua ke ntawm lub zog, toughness, thiab hnav tsis kam.

 

Tshuaj muaj pes tsawg leeg

 

5140 steel feem ntau muaj cov hauv qab no:

 

Cov pa roj carbon (C): 0.38% - 0.43%

Manganese (Mn): 0.75% - 1.00%

Silicon (Si): 0.15% - 0.35%

Chromium (Cr): 0.80% - 1.10%

Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%

Sulfur (S): Tsawg dua lossis sib npaug rau 0.040%

 

Qhov sib ntxiv ntawm chromium thiab lwm yam alloying ntsiab ua rau cov hlau hardenability, lub zog, thiab hnav tsis kam.

Mechanical Properties

 

5140 steel nthuav tawm cov khoom hauv qab no:

 

Tensile zog: 930 - 1080 MPa

Tawm Zog: 785 MPa min

Elongation: 12% min

Txo hauv cheeb tsam: 40% min

Hardness: 207 - 269 HBW

 

Lub zog tensile siab thiab lub zog tawm los ua 5140 steel haum rau cov ntawv thov uas xav tau lub zog thiab ua haujlwm ntev. Qhov zoo elongation thiab txo qis hauv cheeb tsam qhia nws cov ductility thiab muaj peev xwm nqus tau lub zog yam tsis muaj kev tawg.

Kev kho cua sov

 

5140 steel tuaj yeem raug kho cua sov kom ua tiav qib sib txawv hardness thiab cov khoom siv kho tshuab. Cov txheej txheem kev kho cua sov feem ntau suav nrog quenching thiab tempering.

 

quenching: Ua kom sov cov hlau mus rau qhov kub ntawm 845 - 870 degree (1550 - 1600 degree F) thiab tom qab ntawd quenching hauv roj lossis dej.

Tempering: Cua sov cov hlau quenched mus rau qhov kub ntawm 540 - 650 degree (1000 - 1200 degree F) thiab tuav rau ib lub sij hawm tshwj xeeb los txo kev ntxhov siab thiab txhim kho toughness.

 

Cov txheej txheem kho cua sov tuaj yeem cuam tshuam rau cov khoom siv kho tshuab ntawm 5140 steel, tso cai rau nws kom haum rau cov kev siv tshwj xeeb.

Daim ntawv thov

 

5140 steel yog dav siv hauv kev lag luam hauv qab no:

 

Automotive: Rau kev tsim khoom xws li axles, shafts, gears, thiab springs. Cov hlau lub zog thiab hnav tsis kam yog qhov tseem ceeb rau cov ntawv thov no.

Piv txwv li: Hauv lub tsheb thauj khoom lub qag, 5140 steel muab qhov tsim nyog ruaj khov los tuav cov khoom hnyav thiab cov av ntxhib.

Machinery: Siv rau hauv kev tsim cov khoom siv tshuab, xws li lub zog, ncej, thiab bolts. Lub zog siab thiab toughness ntawm 5140 steel ua kom muaj kev ntseeg siab thiab ua haujlwm ntev ntawm cov tshuab.

Piv txwv li: Nyob rau hauv lub tshuab milling muaj lub ntsiab ncej, 5140 steel tuaj yeem tiv taus lub zog sib hloov siab thiab hnav.

Tooling: tuaj yeem siv los ua cov cuab yeej txiav thiab tuag vim nws qhov nyuaj thiab hnav tsis kam.

Piv txwv: Cov hlau stamping tuag ua los ntawm 5140 steel tuaj yeem tsim ntau txhiab qhov chaw nrog tsawg tsawg.

Aerospace: Hauv qee qhov kev siv uas yuav tsum tau muaj zog thiab toughness, xws li tsaws iav Cheebtsam thiab cov khoom siv.

Piv txwv li: Kev tsaws iav strut ntawm lub dav hlau me me tuaj yeem ua los ntawm 5140 steel rau nws lub peev xwm los daws qhov cuam tshuam thiab kev ntxhov siab ntawm kev tsaws.

 

[Ntxig cov duab ntawm ntau yam kev siv ntawm 5140 steel, xws li lub tsheb qag, lub tshuab iav, lub cuab yeej txiav, thiab cov khoom siv dav hlau. Kuj tseem suav nrog cov kab lus hais txog cov piv txwv tshwj xeeb ntawm daim ntawv thov.]

 

Nyob rau hauv xaus, 5140 steel yog ib tug ntau yam alloy steel nrog zoo heev mechanical zog. Nws ua ke ntawm lub zog, toughness, thiab hnav tsis kam ua rau nws haum rau ntau yam kev siv hauv ntau yam lag luam. Lub peev xwm los ua kom sov-kho cov hlau tso cai rau kev hloov kho ntawm nws cov khoom kom tau raws li cov kev xav tau tshwj xeeb. Txawm hais tias nyob rau hauv tsheb, tshuab, cuab yeej, lossis kev siv aerospace, 5140 steel ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua tau zoo thiab kev ntseeg siab ntawm cov khoom thiab cov qauv.
