• Txhim kho Hardness thiab Wear Resistance: Chromium plays lub luag haujlwm tseem ceeb hauv kev txhawb nqa lub hardness ntawm 25CrMo4 steel. Qhov kev nyuaj siab no ua rau cov hlau muaj zog heev rau kev puas tsuaj thiab hnav, uas yog qhov tseem ceeb tshaj plaws rau cov ntawv thov uas cov khoom yuav raug kev sib txhuam thiab kev ntxhov siab. Piv txwv li, nyob rau hauv kev lag luam tsheb, cov khoom ua los ntawm 25CrMo4 steel nrog chromium yuav tsum tau tiv taus qhov sib txhuam thiab kev ntxhov siab los ntawm kev txav mus los.
• Corrosion Resistance: Chromium imparts zoo heev corrosion kuj rau cov hlau. Nws tsim cov txheej txheem oxide tiv thaiv ntawm qhov chaw, ua raws li cov ntaub thaiv npog tiv thaiv xeb thiab kev puas tsuaj hauv qhov chaw corrosive. Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov ntawv thov uas cov hlau tuaj yeem raug ya raws, tshuaj lom neeg, lossis lwm yam corrosive agents.
• Txhim kho Cov Khoom Kub Kub Zoo: Chromium kuj pab txhim kho kev ruaj ntseg ntawm cov hlau thaum kub kub. Nws ua rau cov hlau tiv thaiv softening thiab tswj nws cov khoom siv kho mob txawm tias raug kub hnyiab. Qhov no ua rau 25CrMo4 steel nrog chromium haum rau cov ntawv thov hauv qhov chaw kub kub, xws li hauv kev lag luam aerospace thiab lub zog tsim hluav taws xob.
Molybdenum (Molybdenum):
• Ua kom muaj zog thiab tawv: Molybdenum yog ib qho tseem ceeb rau kev txhim kho lub zog thiab tawv ntawm 25CrMo4 steel. Nws muab cov hlau muaj peev xwm tiv taus cov khoom hnyav thiab cuam tshuam yam tsis muaj kev tawg yooj yim. Qhov no yog qhov tseem ceeb heev rau cov ntawv thov uas cov hlau xav tau los tiv thaiv kev ntxhov siab, xws li hauv tshuab thiab kev tsim kho.
• Txhim kho Hardenability: Molybdenum pab txhim kho lub hardenability ntawm cov hlau. Qhov no txhais tau hais tias nws tso cai rau cov hlau kom hardened zoo dua thaum lub sij hawm kho cua sov txheej txheem, uas ua rau ib tug ntau uniform thiab muaj zog microstructure. Qhov no yog qhov zoo rau cov ntawv thov uas xav tau qib siab hardness thiab lub zog.
• Txhim kho Creep Resistance: Molybdenum kuj pab txhawb kev nkag siab zoo dua. Creep yog qhov qeeb deformation ntawm cov khoom nyob rau hauv qhov kev ntxhov siab tas li dhau sijhawm. Hauv cov ntawv thov uas cov hlau yuav raug kev nyuaj siab mus ntev, xws li hauv cov kav dej kub lossis cov hlab ntsha siab, qhov sib ntxiv ntawm molybdenum pab tiv thaiv kev nkag thiab ua kom muaj kev ncaj ncees mus ntev ntawm cov qauv.
Hauv kev xaus, cov ntsiab lus alloying hauv 25CrMo4 steel, xws li chromium thiab molybdenum, ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom thiab qhov zoo ntawm cov khoom kawg. Lawv lub xub ntiag txhim khu lub hardness, hnav tsis kam, corrosion kuj, lub zog, toughness, thiab high-temperature zog ntawm steel, ua rau nws haum rau ntau yam kev siv nyob rau hauv ntau yam lag luam. Los ntawm kev ua tib zoo tswj qhov sib ntxiv ntawm cov alloying ntsiab lus thaum lub sij hawm tsim khoom, manufacturers tuaj yeem tsim 25CrMo4 steel nrog cov khoom tshwj xeeb tsim kom tau raws li qhov xav tau ntawm kev siv sib txawv.
