Vim txoj kev loj hlob sai ntawm kuv lub teb chaws lub dav hlau tsim kev lag luam, cov kev ua tau zoo ntawm domestic aircraft tau sai heev, thiab qhov kev thov rau stainless hlau precision kav kuj tau nce ntau. Feem ntau hais lus, cov kav dej stainless hlau koom nrog hauv daim teb no feem ntau suav nrog precision stainless hlau kav thiab kub kub. Kev siv txhua xyoo ntawm cov kav dej hlau thiab cov kav hlau corrugated yog li 5, 000 tons. Ntawm lawv, feem ntau siv yog high nickel alloy stainless hlau kav thiab 600 series stainless hlau kav, xws li 63{{30}}}/631 cov ntaub ntawv. Qee yam ntawm cov khoom siv steel hlau tshiab kuj tseem siv tau los ua cov khoom siv hauv tsev tshiab uas ua tau zoo ntawm cov khoom siv hlau stainless hlau uas tuaj yeem siv rau hauv kev tsim cov dav hlau tshiab hauv tsev. Cov khoom tseem ceeb yog 16Co14Ni10Cr2Mo, 23Co14Ni12Cr3Mo, TM210A, 16Cr3NiWMoVNb, 0Cr13Ni8Mo2Al, 1Cr15Ni4Mo3N, 0Cr15Ni5Cu2Ti, 0CC20NTCuMoNiC.
Nrog rau kev txhim kho tas mus li thiab kev vam meej ntawm kuv lub teb chaws aviation manufacturing technology, tshwj xeeb tshaj yog cov tiam tshiab ntawm lub dav hlau muaj ntau txoj cai nruj rau kev ua tau zoo ntawm cov khoom siv. Ntawm lawv, cov qauv hlau thiab stainless hlau cov ntaub ntawv tshiab nrog lub zog siab, siab toughness, zoo qaug zog tsis kam thiab siab purity yog dav siv nyob rau hauv tshiab aircraft. Ib tug xov tooj ntawm high-kev ua tau zoo steels thiab stainless hlau rau aviation, xws li AF1410AerMet100, PH13-8Mo, 18Ni (300), 16Х3НВФМБ, 13Х15Н4АМ{11}}Ш/imit, thiab lwm yam. Tuam Tshoj. Piv nrog rau cov hlau zoo tib yam, cov txheej txheem kev ua haujlwm ntawm cov qauv hlau tshiab thiab cov hlau tsis zoo rau kev dav hlau yog pom tseeb dua.
Tsis tas li ntawd, kev thov hauv tsev rau kev txiav riam phom yog nce ntxiv, thiab kev siv cov thev naus laus zis tshiab los tsim cov cuab yeej siv tub rog tshiab kuj tseem yuav tsum nruj. Raws li kev sib ntaus sib tua muaj kev txhawj xeeb, vim muaj kev nruj heev ntawm kev tawm mus thiab tsaws, kev ua haujlwm ntawm cov iav tsaws yog txwv. Muaj cov kev xav tau siab heev.
Cov yam ntxwv ntawm kev ua haujlwm siab stainless hlau yeeb nkab
Cov yam ntxwv ntawm kev ua haujlwm siab stainless hlau yeeb nkab nyob rau hauv daim ntawv thov teb yog cov muaj zog thiab toughness, zoo heev vuam kev ua tau zoo, zoo qaug zog tsis kam thiab kev nyuaj siab corrosion kuj, thiab insensitive rau notches thiab hydrogen embrittlement. Ntawm lawv, AF1410 steel yog cov qib steel nkaus xwb uas tuaj yeem siv rau kev puas tsuaj rau kev tsim kho kom deb li deb, thiab nws tau siv los ua lub dav hlau tiaj tus ncej; AerMet100 steel tau ua tiav tiav los ntawm kev kho cov alloy muaj pes tsawg leeg ntawm lub hauv paus ntawm AF1410 steel, thiab nws lub zog tensile ntau dua 1 930 MPa Nws yog cov hlau uas muaj lub zog zoo tshaj plaws thiab lub zog tam sim no. Nws tau ua tiav zoo siv hauv kev tsaws iav ntawm F / A18 cov neeg nqa dav hlau, F22 thiab F35 aircraft, armor tiv thaiv ntawm Comanche gunships, aviation black box tsev nyob, thiab lwm yam. Nws kuj yog ib tug tiam tshiab ntawm domestic aircraft Cov khoom ntawm kev xaiv rau tsaws iav. .
Tsis tas li ntawd, PH13-8Mo steel yog martensitic nag lossis daus hardening stainless hlau, uas muaj lub zog siab tshaj plaws ntawm cov nag lossis daus hardening stainless hlau uas twb muaj lawm. Nws feem ntau yog siv los ua cov ntu loj loj nrog lub zog tawm los txog li 1 515 MPa, zoo plasticity, thiab cov khoom tsis-anisotropic. Dimensional qhov chaw tsim khoom. Cov ntawv thov satellite hauv tsev yog booming. Cov pej xeem satellites tau siv dav hauv ntau qhov chaw xws li kev soj ntsuam hauv ntiaj teb, kev sib txuas lus thiab kev tshaj tawm, kev taw qhia thiab kev tso chaw, thiab tau ua tiav cov txiaj ntsig tseem ceeb hauv zej zog thiab kev lag luam. Tuam Tshoj tau tsim cov kev siv satellite xws li kev sib txuas lus satellite, satellite meteorology, satellite kev tshawb fawb, satellite navigation thiab positioning, satellite microgravity thwmsim, thiab kev tshawb fawb chaw. Txoj kev loj hlob sai ntawm cov thev naus laus zis thev naus laus zis no yog sib cais los ntawm kev txhim kho sai ntawm stainless hlau raj thev naus laus zis, uas ua rau txhawb kev nce qib sai ntawm stainless hlau raj ntau lawm thiab kev siv tshuab.
