Puas yog INCONEL muaj zog dua hlau?
Inconel
Lub npe lag luam rau cov khoom zoo nickel-chromium alloys yog Inconel. Cov khoom siv no tuaj yeem tiv taus cov alloy-hom kub kub (txog 2, 000 degree F) nrog xoom lub zog poob. Cov khoom no yog qhov tsim nyog heev txawm tias qhov kub thiab txias.
Cov khoom siv kho tshuab ntawm Inconel ntawm chav tsev kub yog qhov zoo heev. Yog li koj paub, Inconel qib 725 muaj lub zog tensile ntawm txog 180 ksi; uas yog ob zaug lub zog ntawm cov qauv hlau. Lwm cov alloys, xws li Inconel 718, yog toughened los tiv thaiv los nag, ua rau lawv muaj zog. Corrosion thiab nws cov kwv tij: Corrosion, oxidation, corrosion cracking thiab crevice corrosion tsis cuam tshuam rau Inconel.
Inconel cov khoom zoo heev ua tau raws li cov kev xav tau ntawm cov ntawv thov. Txawm li cas los xij, cov ntaub ntawv zoo li Inconel kim dua titanium, stainless hlau, thiab txhuas.
Machining Inconel
Vim nws lub zog siab, kev ua haujlwm yog qhov nyuaj. Inconel nyuaj heev uas cov cuab yeej txiav tuaj yeem ua puas thaum lub tshuab ua haujlwm thiab cov khoom tuaj yeem sib tw thiab khoov.
Immersing Inconel nyob rau hauv ib qho kev daws yuav txo cov khoom hardness thiab tiv thaiv kev txiav cov cuab yeej hnav. Rau machining Inconel, cov cuab yeej ceramic raug pom zoo vim nws muab kev txiav nrawm thiab tsis muaj kev cuam tshuam, ua rau kev ua haujlwm tau zoo dua. Pecking yuav tsum zam vim qhov no tuaj yeem ua rau txoj haujlwm nyuaj.
Vuam Inconel
Inconel tsis yooj yim rau vuam vim tawg. Tab sis Inconel alloys tuaj yeem welded zoo li Inconel 625 - alloy uas yooj yim sau sai thiab feem ntau welded siv tungsten inert gas (TIG). Cov txheej txheem vuam no feem ntau tsis tas yuav muab tub lim tab sis ua haujlwm zoo rau kev koom nrog Inconel. Yog vim li cas thiaj pom zoo.
Kev siv Inconel
Inconel yog cov khoom ntawm kev xaiv thaum kub hnyav thiab corrosion yog teeb meem, tshwj xeeb tshaj yog thaum lwm cov hlau tsis resistant rau oxidation thiab deformation los ntawm kub kub.
Inconel muaj qhov kub thiab txias thiab tshuaj tiv thaiv zoo heev thiab yog siv rau hauv cov tshuab tso pa rau kev sib tw tsheb, turbines, dav hlau cav, thiab hauv cov roj thiab roj, aerospace, thiab marine sectors uas yuav tsum muaj cov tshuab hnyav.
Stainless hlau
Stainless hlau muaj zog, tsis muaj hlau nplaum thiab thermochemically ruaj khov. Nws yog ib qho khoom siv yooj yim thiab pheej yig los tsim khoom. Stainless hlau 304 qib yog cov qauv kev lag luam rau kev tsim cov pa tawm. Qib 304 sawv tawm rau kev ua haujlwm siab thiab ua haujlwm ntev ntev hauv kev siv tsheb kauj vab uas pheej yig.
Tsis zoo li titanium alloys, uas yog kim heev rau loj-tsim maus taus pa tshuab, steel alloys kuj pheej yig thiab haum rau siv txhua hnub. Hlau yog pheej yig dua Inconel. Tab sis cov hlau hnyav dua li titanium thiab muaj zog tensile qis, thaum Inconel muaj zog heev. Tias yog vim li cas nws thiaj li txwv rau kev ua haujlwm tso pa tawm. Raws li rau lub suab, cov phab ntsa tuab ntawm cov hlau tsim ib daim ntawv uas tsis tshua muaj suab nrov piv rau titanium. Suab metallic!
Ib yam li ntawd, steel yog corrosion-resistant thiab muaj zog heev. Feem ntau, av tsheb kauj vab taub hau raj yog ua los ntawm stainless hlau.
Stainless hlau ua
Qee cov qib stainless hlau tau yooj yim rau kev ua haujlwm dua li lwm tus, nyob ntawm cov ntsiab lus ntxhia tau txais. Feem ntau, austenitic stainless hlau yog suav hais tias nyuaj rau tshuab. 400 series steel yog yooj yim rau tshuab dua 300 series (xws li 304 thiab 316 qib). Qib 303 yog qhov yooj yim stainless hlau ua haujlwm nrog. Qib 316 steel yog qhov nyuaj thiab xav tau cov cuab yeej txiav tshwj xeeb.
Qhov sib ntxiv ntawm selenium thiab sulfur ua rau stainless hlau yooj yim rau tshuab. Tab sis qhov no tuaj yeem corrode cov khoom siv raw thiab rhuav tshem cov vuam.
welded stainless hlau
Qhov tsawg carbon steel muaj, qhov yooj yim dua nws yog welding. Qib 304 stainless hlau muaj qhov siab tshaj plaws cov pa roj carbon ntsiab lus ntawm 0.08%, thaum qib 304L muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%.
Kev siv cov hlau stainless
Stainless hlau lub zog siab, corrosion tsis kam, mechanical efficiency thiab kev lag luam ua rau nws tsim nyog rau cov khoom loj ntawm maus taus pa, nrog rau cov khoom noj, kev tsim kho, kev kho mob thiab kev lag luam marine.
