Ib, P20 steel: feem ntau siv universal steel hauv kev txhaj tshuaj pwm
P20 steel yog qis- alloy, ua ntej- hardened steel uas yog nrov heev hauv kev txhaj tshuaj molding lag luam. P20 steel feem ntau yog 28-32HRC nyuaj, uas ua rau nws yooj yim rau kev ua hauj lwm nrog thiab polish. Qhov no ua rau nws xaiv zoo rau txhaj tshuaj pwmuas tsis kav ntev heev.
P20 steel yog qhov kev xaiv zoo vim nws tsis kim heev, yooj yim rau kev ua haujlwm nrog, thiab tuaj yeem ua kom tawv thiab tiv taus hnav los ntawm nitriding lossis quenching kho. P20 steel yog qhov kev xaiv zoo rau cov khoom yas uas tsis tas yuav tsum tau ua sai sai lossis tsis tas yuav tiv taus pwm corrosion.
2, H13 steel yog qhov kev xaiv zoo tshaj plaws rau pwm rau siab -kub technical plastics.
H13 steel yog ib hom kev ua haujlwm kub tuag hlau uas muaj zog heev, tiv taus hnav zoo, thiab tuaj yeem tiv taus cua sov. Nws yog ib txwm nyob nruab nrab ntawm 45 thiab 50 HRC nyuaj, thiab kev kho cua sov tuaj yeem ua rau nws ruaj khov dua. H13 steel yog qhov zoo rau kev ua kom siab -kub engineering yas pwm, xws li nylon (PA), polyphenylene sulfide (PPS), thiab polycarbonate (PC) yas qhov chaw, vim tias nws tuaj yeem tswj tau qhov kub thiab txias.
Siab- cov yas kub kub tuaj yeem ua rau pwm tuaj yeem khoov thiab hnav thaum lub sijhawm txhaj tshuaj molding. Ntawm qhov tod tes, H13 steel lub thermal stability thiab hnav tsis kam tuaj yeem pab cov pwm muaj sia nyob ntev dua. H13 steel yog me ntsis nyuaj rau kev ua haujlwm nrog ntau dua P20, tab sis nws muaj peev xwm tswj tau qhov kub thiab txias thiab siv sij hawm ntev ua rau nws zoo meej rau cov kub khiav pwm thiab pwm siv rau loj - nplai ntau lawm.
3, S136 steel thiab 420 stainless hlau yog cov kev xaiv zoo tshaj plaws rau cov pwm uas yuav tsum tau ci thiab tiv taus xeb.
Thaum ua cov pwm txhaj tshuaj, cov hlau siv rau cov pwm yuav tsum muaj qhov zoo heev rau cov khoom yas ntshiab thiab cov khoom siv yas siab gloss. Vim tias lawv tiv taus corrosion zoo thiab polish zoo, S136 steel thiab 420 stainless hlau yog tam sim no cov hlau zoo tshaj plaws. S136 steel yog ib hom stainless hlau uas tau hardened ua ntej siv. Nws hardness feem ntau yog nyob nruab nrab ntawm 38 thiab 42HRC.
420 stainless hlau kuj tseem tiv taus xeb thiab tsim nyog rau cov pwm uas yuav kov cov dej los yog cov kuab tshuaj rau lub sijhawm ntev. S136 thiab 420 stainless hlau tuaj yeem ua cov khoom txhaj tshuaj molded nrog cov chaw du heev thiab tsis muaj qhov tsis xws luag los ntawm kev siv txoj kev kho cua sov thiab polishing. Xaiv cov hlau zoo li no rau kev txhaj tshuaj pwm tsim tsis tuaj yeem ua rau cov khoom yas zoo dua,
4,718H steel thiab hnav siab siab-cov hlau tsis muaj zog: kev lees paub ua pwm hauv ntau qhov ntau
Thaum nws los txog rau pwm rau siab -yield yas qhov chaw, xws li cov siv nyob rau hauv lub tsheb thiab factories, pwm lub neej thiab hnav kuj tseem ceeb heev. Cov neeg siv 718H steel thiab lwm yam hlau uas tiv taus hnav, suav nrog D2 thiab DC53, ntau hauvtxhaj tshuaj pwm.718H steel tuaj yeem nyuaj heev, nrog rau hardness ntawm 50 txog 52 HRC. Nws tseem muaj zog heev thiab tiv taus hnav, uas ua rau nws zoo meej rau cov pwm uas yuav tsum tau txhaj ntau heev.
Siv cov hlau uas tiv taus hnav tuaj yeem txuag cov nqi kho pwm thiab ua kom ntau lawm. Rau cov neeg tsim pwm, hnav siab siab- cov hlau tsis muaj zog yog ib qho nyuaj rau kev ua haujlwm nrog thiab kim, tab sis nws muaj qhov zoo meej thaum nws los ua ntau yam yas uas kuj hnav siab heev -resistant. Los ntawm kev siv txoj kev kho cua sov kom raug,
5, Nickel alloy steel yog qhov siab -kev xaiv kawg uas tawm tsam
Nickel alloy steel yog tsim los ntawm kev ntxiv npib tsib xee rau P20 lossis 718H hlau. Qhov no ua rau cov hlau tawv dua thiab ua rau nws tiv taus corrosion thiab zoo dua ntawm polishing. Nickel alloy steel feem ntau yog siv los ua cov pwm txhaj tshuaj rau cov khoom yas uas yuav tsum tau ua kom meej thiab ci,
Cov neeg tsim pwm tuaj yeem tau txais qhov zoo tshaj plaws ntawm ob lub ntiaj teb los ntawm kev siv cov nickel alloy steel: nws ua rau pwm yooj yim ua hauj lwm nrog thiab kav ntev dua thaum tseem muab qhov chaw siab gloss tiav. Ntau dua thiab siab dua -kawg txhaj pwm yog siv cov hlau no,
6, Cov hlau ua haujlwm txias thiab muaj zog alloy
Txias wrought hlau thiab muaj zog alloys kuj tseem tsim nyog rau kev txhaj tshuaj pwm, nrog rau cov hlau tsis tu ncua P20, H13, S136, thiab 718H. D2 thiab DC53 yog ob qho piv txwv ntawm cov hlau ua haujlwm txias uas tiv taus hnav heev. Lawv yog qhov zoo rau kev ua cov khoom yas lossis cov pwm uas yuav tsum tau ua kom ntev ntev hauv cov pwm kab noj hniav. Cov neeg feem ntau siv cov hlau alloy (tungsten steel) rau kev hnav hauv zos -cov cores resistant los yog inserts los ua pwm ntev dua thiab tiv taus hnav.
Cov hlau no nyuaj ua haujlwm nrog thiab kim, tab sis nws tsis tuaj yeem hloov pauv hauv pwm rau cov khoom yas uas yuav tsum tau hnav heev - tiv taus thiab meej. Txhaj pwm tuaj yeem tau txais qhov sib npaug zoo tshaj plaws ntawm kev hnav tsis kam, kev ua tau zoo, thiab tus nqi los ntawm kev siv cov hlau sib txawv hauv txoj kev ntse.
