2. Zoo toughness: Cov khoom muaj zoo heev toughness thiab muaj peev xwm tswj tau zoo durability txawm nyob rau hauv loj deformation los yog hnyav load.
3. Zoo thermal stability: 30W4Cr2V muaj qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm tau ntev hauv qhov kub thiab txias.
4. Zoo corrosion kuj: cov khoom muaj corrosion kuj zoo nyob rau hauv ntub los yog acid-alkali ib puag ncig, ncua kev pab cuam lub neej ntawm lub caij nplooj ntoos hlav.
3. Daim ntawv thov teb ntawm 30W4Cr2V
1. Automotive kev lag luam: 30W4Cr2V yog dav siv nyob rau hauv automotive shock absorbers, suspension systems, caij nplooj ntoos hlav lub rooj zaum thiab lwm yam khoom, uas muaj peev xwm muab ruaj khov thiab xis caij.
2. Kev tsim khoom siv tshuab: Hauv kev tsim khoom siv tshuab, 30W4Cr2V feem ntau yog siv rau txhua yam kev sib tw, kis tau tus mob, qhov ntsuas qhov tseeb, thiab lwm yam, kom ntseeg tau tias lub tshuab ua haujlwm zoo thiab raug.
3. Tub rog aviation: 30W4Cr2V muaj zoo heev toughness thiab kub tsis kam, yog li nws yog dav siv nyob rau hauv cov tub rog aviation teb ntawm missiles, aircraft zaum springs, spacecraft bushings thiab hais txog.
4. Kev kho cua sov txheej txheem ntawm 30W4Cr2V
Cov txheej txheem kev kho cua sov ntawm 30W4Cr2V suav nrog annealing, normalizing, quenching thiab tempering los txhim kho lub zog thiab hardness ntawm cov khoom.
1. Annealing: Cov khoom yog rhuab mus rau qhov tsim nyog kub thiab txias rau chav tsev kub tom qab ib tug tej lub sij hawm kom tshem tawm cov kev ntxhov siab nyob rau hauv cov khoom thiab txhim kho lub machinability.
2. Normalizing: Cov khoom siv annealed yog rhuab mus rau qhov kub thiab txias, thiab tom qab ntawd txias sai sai rau hauv chav tsev kub, uas tuaj yeem txhim kho qhov hardness thiab lub zog ntawm cov khoom.
3. Quenching: cov khoom normalizing yog sai txias rau chav tsev kub, thiaj li hais tias nws tsim martensitic qauv thiab txhim kho hardness.
4. Tempering: Cov khoom tom qab quenching yog reheated rau qhov tsim nyog qhov kub thiab txias preservation, thiab ces txias rau chav tsev kub, uas yuav txo tau lub brittleness ntawm cov khoom thiab txhim kho lub toughness.
V. Parameter cov ntaub ntawv ntawm 30W4Cr2V
1. Lub zog muaj zog: Ntau dua lossis sib npaug ntawm 1080MPa
2. Lub zog tensile: Ntau dua lossis sib npaug ntawm 1275MPa
3. Elastic modulus: 195-205 GPa
4. Hardness: HRC 43-49
Vi. Cov ntsiab lus
Raws li cov khoom siv caij nplooj ntoos hlav zoo, 30W4Cr2V muaj lub zog siab, zoo toughness thiab thermal stability, thiab yog dav siv nyob rau hauv kev lag luam automotive, machinery manufacturing, tub rog aviation thiab lwm yam teb. Los ntawm cov txheej txheem kho cua sov tsim nyog, nws qhov kev ua tau zoo tuaj yeem txhim kho ntxiv, thiab ua tau raws li qhov yuav tsum tau ua ntawm ntau yam kev ua haujlwm nyuaj. Cov ntaub ntawv nthuav dav thiab cov ncauj lus ntxaws ntxaws ntawm 30W4Cr2V yuav pab kom nkag siab zoo dua thiab siv cov khoom siv no.
