Tungsten steel: Cov khoom tiav muaj li 18% tungsten alloy steel. Tungsten steel belongs rau hard alloy, tseem hu ua tungsten-titanium alloy. Lub hardness yog 10K Vickers, thib ob tsuas yog pob zeb diamond. Vim li no, tungsten steel khoom (feem ntau tungsten steel watches) muaj cov yam ntxwv ntawm tsis yooj yim hnav. Nws feem ntau yog siv rau hauv cov cuab yeej tshuab dhos, cuam tshuam cov laum khoom, iav cutter khoom, pobzeb cutters. Nws muaj zog thiab tsis ntshai ntawm annealing, tab sis nws yog nkig.
Cemented carbide: belongs rau thaj tsam ntawm hmoov metallurgy. Cemented carbide, tseem hu ua hlau ceramic, yog cov ceramic uas muaj qee yam khoom ntawm cov hlau, uas yog ua los ntawm cov hlau carbides (WC, TaC, TiC, NbC, thiab lwm yam) los yog hlau oxides (xws li Al2O3, ZrO2, thiab lwm yam) raws li cov khoom tseem ceeb, thiab qhov tsim nyog ntawm cov hmoov hlau (Co, Cr, Mo, Ni, Fe yog ntxiv hmoov los ntawm hlau, thiab lwm yam). Cobalt (Co) yog siv los ua kom muaj kev sib raug zoo hauv cov hlau, uas yog, thaum lub sij hawm sintering, nws tuaj yeem nyob ib puag ncig cov tungsten carbide (WC) hmoov thiab sib khi ua ke. Tom qab txias, nws dhau los ua cemented carbide. (Cov nyhuv yog sib npaug rau cov cement hauv pob zeb). Cov ntsiab lus feem ntau yog: 3% -30%. Tungsten carbide (WC) yog cov khoom tseem ceeb uas txiav txim siab qee cov khoom siv hlau ntawm cov cemented carbide lossis cermet, suav txog 70% -97% ntawm tag nrho cov khoom (qhov hnyav piv). Nws yog dav siv nyob rau hauv hnav-resistant, high-temperature-resistant, corrosion-resistant qhov chaw los yog riam thiab cov cuab yeej taub hau nyob rau hauv hnyav ua hauj lwm ib puag ncig.
Tungsten steel belongs rau cemented carbide, tab sis cemented carbide tsis tas tungsten hlau. Niaj hnub no, cov neeg siv khoom hauv Taiwan thiab cov tebchaws Esxias sab hnub tuaj nyiam siv lub sijhawm tungsten steel. Yog tias koj tham nrog lawv kom meej, koj yuav pom tias feem ntau ntawm lawv tseem xa mus rau cemented carbide.
Qhov sib txawv ntawm tungsten steel thiab cemented carbide yog tungsten steel, tseem hu ua high-speed steel los yog cov cuab yeej steel, yog tsim los ntawm kev ntxiv tungsten hlau li tungsten raw khoom rau molten steel siv steelmaking technology, kuj hu ua high-speed steel los yog cov cuab yeej steel, thiab nws cov ntsiab lus tungsten feem ntau yog 15-25%; thaum cemented carbide yog tsim los ntawm sintering tungsten carbide ua lub ntsiab lub cev nrog cobalt los yog lwm yam sib txuas hlau siv hmoov metallurgy tshuab, thiab nws cov ntsiab lus tungsten feem ntau yog siab dua 80%. Cias muab, txhua yam uas muaj hardness tshaj HRC65 tsuav nws yog ib qho alloy yuav hu ua cemented carbide, thiab tungsten steel tsuas yog ib hom cemented carbide nrog hardness ntawm HRC85 thiab 92, thiab feem ntau yog siv los ua riam.
