Inconel 686 alloy yog dab tsi?
Inconel 686 alloy yog nickel-based alloy uas nws cov khoom tseem ceeb suav nrog:
1. Nickel (Ni): accounting rau 50 ~ 60% ntawm tag nrho cov muaj pes tsawg leeg, muab zoo corrosion kuj thiab kub siab zog.
2. Chromium (Cr): accounting rau 19 ~ 23% ntawm tag nrho cov muaj pes tsawg leeg, uas ua rau kom cov corrosion kuj thiab oxidation kuj ntawm cov khoom.
3. Molybdenum (Mo): accounting rau 8 ~ 10% ntawm tag nrho cov muaj pes tsawg leeg, uas txhim kho corrosion kuj thiab kub siab zog ntawm cov khoom.
4. Tungsten (W): accounting rau 3 ~ 4% ntawm tag nrho cov muaj pes tsawg leeg, uas txhim kho corrosion kuj thiab kub siab zog ntawm cov khoom.
Inconel 686 muaj cov yam ntxwv hauv qab no:
1. Nws muaj qhov zoo tiv thaiv corrosion los ntawm kev txo qis, oxidizing thiab nitriding media.
2. Nws muaj kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg ntawm chav tsev kub thiab kub.
3. Nws muaj qhov zoo tiv thaiv corrosion los ntawm cov roj chlorine qhuav thiab hydrogen chloride gas.
4. Nws muaj cov khoom siv zoo ntawm xoom, chav tsev kub thiab kub.
5. Nws muaj qhov zoo creep rupture tsis kam thiab raug pom zoo siv rau saum 700 degree.
Tsis tas li ntawd, Inconel 686 alloy tseem muaj me me ntawm tooj liab, hlau, manganese, silicon, carbon thiab lwm yam khoom. Qhov sib ntxiv ntawm cov ntsiab lus no tseem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
Inconel 686 txheej txheem kev ua tau zoo thiab cov kev xav tau:
Thermal ua
1. Thermal processing kub yog 1200 degree ~ 900 degree, thiab txoj kev txias yog dej quenching los yog ceev cua txias.
2. Yuav kom tau txais qhov zoo tshaj plaws corrosion kuj thiab cov qauv siv lead ua zoo tshaj plaws, kev kho cua sov yuav tsum tau ua tom qab ua cov cua sov.
3. Cov ntaub ntawv tuaj yeem raug pub ncaj qha rau hauv qhov cub sov.
Ua haujlwm txias
1. Cov ntaub ntawv ua haujlwm txias yuav tsum nyob rau hauv ib qho annealed los yog daws cov cua sov kho lub xeev. Kev ua haujlwm hardening tus nqi ntawm 686 alloy yog ze rau ntawm austenitic stainless hlau, yog li cov khoom siv zoo sib xws tuaj yeem xaiv.
2. Intermediate annealing yuav tsum tau ua thaum lub sijhawm ua haujlwm txias.
3. Thaum qhov txias ua hauj lwm ntau dua 5%, lub workpiece yuav tsum tau kho.
4. Txhawm rau txo cov khoom hnav, cov pwm yuav tsum tau ua los ntawm cov cuab yeej alloy steel, carbide lossis cam khwb cia hlau.
Inconel 686 vuam txheej txheem
Cov hlau muaj qhov zoo vuam zoo thiab tuaj yeem txuas tau los ntawm ntau txoj hauv kev xws li arc vuam, argon arc vuam, tsis kam vuam thiab brazing. Loj los yog complex welded structural qhov chaw yuav tsum tau annealed ntawm 870 degree rau 1 teev tom qab vuam kom tshem tawm vuam kev nyuaj siab.
Nyob rau hauv dav dav, Inconel 686 alloy steel muaj zoo heev corrosion kuj, siab kub zog, zoo plasticity thiab toughness, thiab yog dav siv nyob rau hauv chemical kev lag luam, roj av, natural gas,
Aerospace thiab lwm yam kev lag luam.
