Inconel725 siab kub alloy khoom
Inconel725 (UNS N07725) Alloy725 npib tsib xee-raws li kub kub alloy
Taw qhia:
Inconel 725 alloy yog nickel-chromium-molybdenum-niobium alloy nrog zoo corrosion kuj. Tom qab kev laus kev kho cua sov, nws tuaj yeem ua kom lub zog ntawm cov hlau zoo heev thiab txhim kho cov ductility thiab tensile lub zog ntawm cov hlau. Cov hlau tseem muaj zog tiv thaiv kev ntxhov siab corrosion.

Daim ntawv thov teb ntawm Inconel 725:
Siv rau cov yeeb nkab fittings, pob qij txha thiab bearings hauv cov khoom siv acid-resistant. Nws kuj yog siv dav hauv cov khoom siv nkoj nkoj hiav txwv.
1. Nyuaj hauv kev ua N07725 siab kub alloy
N07725 high-temperature alloy muaj ib tug high degree ntawm alloying, tsis tshua muaj thermal conductivity, siab txiav kub, loj txiav quab yuam, hnyav ua hauj lwm hardening, ntau nyuaj cov ntsiab lus, tsawg ua efficiency, hnyav hnyav hnyav, thiab siab txiav nqi.
Yog tias cov cuab yeej carbide tau siv los ua cov txheej txheem, nws yuav ua rau cov cuab yeej hnyav hnyav, ua rau nws nyuaj los lav qhov zoo ntawm cov tshuab ua kom zoo, thiab nws yooj yim rau adhesion, ua rau muaj kev hloov pauv ntau zaus. Yog li ntawd, siv CBN cov cuab yeej yog ib qho kev xaiv zoo dua, uas tuaj yeem ua kom muaj txiaj ntsig, txo cov cuab yeej hnav, thiab txhim kho qhov zoo ntawm qhov chaw.
2. Qhov zoo ntawm CBN cov cuab yeej rau kev ua N07725 siab kub alloy
1. CBN cov cuab yeej muaj siab hardness thiab tsis ntshai ntawm high-temperature alloy hardening. Lub hardness ntawm CBN cov cuab yeej yog siab heev, feem ntau yog hais txog 8000 ~ 9000HV, yog li txawm thaum ua high-hardness high-temperature alloys, CBN cov cuab yeej tau yooj yim ua tiav high-ceev txiav.
2. CBN cov cuab yeej txiav muaj cov cua sov zoo thiab tuaj yeem tiv taus qhov kub siab dua. Lub tshav kub tsis kam ntawm CBN cov cuab yeej yog 144 ~ 1500 degree. Txawm hais tias ib qho loj ntawm kev txiav cov cua sov yuav raug tsim thaum lub sij hawm kub-kub alloy txiav, uas tej zaum yuav siab li 1000 degree, nws yuav tsis cuam tshuam rau ib txwm siv CBN cov cuab yeej.
3. CBN cov cuab yeej txiav tau zoo hnav tsis kam thiab tshuaj lom neeg ruaj khov. High-temperature alloys muaj ntau cov carbides, nitrides, borides thiab intermetallic compounds, uas tsim cov ntsiab lus me me nyuaj thiab ua rau cov cuab yeej hnav. CBN cov cuab yeej muaj zog hnav tsis kam, uas txo qis cov cuab yeej hloov pauv thiab txhim kho kev ua haujlwm zoo.
3. Cov ntaub ntawv kawm ntawm CBN cov cuab yeej ua haujlwm N07725 siab kub alloy workpiece
Txawm hais tias qhov kev ua tau zoo ntawm N07725 high-temperature alloy yog qhov tsis zoo thiab nws yog qhov nyuaj tshaj plaws los txiav cov yas nyuaj-rau-txiav cov ntaub ntawv, tsuav yog cov cuab yeej ua haujlwm tsim nyog thiab cov kev txiav tsim nyog raug xaiv, cov txheej txheem txiav tuaj yeem ua tiav. ua tiav.
