Titanium alloy thiab stainless hlau sib piv
Hauv ob qho kev lag luam thiab cov neeg siv khoom txhua hnub, titanium alloys thiab stainless hlau tau ib txwm yog ob lub siab xav tias yog cov ntaub ntawv zoo nkauj. Tus qub yog muaj npe nyob rau hauv Aerospace teb rau nws "lub teeb ci ntsa iab thiab lub zog ua tsaug rau nws" kev lag luam ua tsaug rau nws "kev lag luam thiab ruaj khov". Txawm hais tias nyob rau ntawm cov haujlwm sib txawv, lawv yeej sib tshooj tau ntau yam ntawm kev ua tau zoo, nqi, thiab cov ntawv teev cov xwm txheej. Kev soj ntsuam tob ntawm lawv lub zog lub cev, kev ua lag luam, txoj haujlwm ua lag luam tuaj yeem muab cov kev xaiv xaiv tau ntau yam.
Lub cev siv lub cev: Qhov kawg showdown ntawm kev sib tw thiab qhov kub siab kuj tsis kam
Titanium alloys muaj qhov ntom ntom ntawm tsuas yog 4.5 g / cm³, tsuas yog 57% uas ntawm stainless hlau. Cov xeeb ceem no muab rau lawv muaj txiaj ntsig zoo hauv cov teb hnyav xws li cov dav hlau lub cav thiab nkoj siab Hulls. Piv txwv li, tom qab hloov cov hlau tsis muaj roj titanium alloy nyob rau hauv cov av iav, qhov hnyav tag nrho tau txo los ntawm 40%, txhim kho kev ua tau roj tag nrho. Txawm li cas los xij, lub teeb yuag tsis yog qhov zoo tshaj plaws ntawm titanium alloys-lawv qib siab, tso cai rau ncua sijhawm, thaum 316 stainless hlau softens tseem ceeb tshaj 800 degree. Qhov kev kub siab no ua rau titanium alloys cov khoom nyiam rau cov neeg muaj kuab lom thiab cov fais fab nroj tsuag thiab lub zog hluav taws xob nuclear.
Stainless hlau, ntawm qhov tod tes, muaj ntau qhov sib npaug thiab cov cuab yeej siv lub cev. Txawm hais tias nws muaj qhov ntom ntom ntom ntom, nws tuaj yeem tsim nyob rau hauv Ultra-nyias cov ntawv qhia (0.1mm tuab yuav tsum muaj cov ntawv thov txias xws li lub tsev kab hlau sib dhos thiab cov khoom siv nyiaj txiag. Tsis tas li ntawd, Stainless hlau muaj qis dua thermal conductivity (15-20 · k) dua li titanium alloys (6.7-11,5 W /Thrware uas xav tau kev hloov pauv kub ceev (xws li hauv qab ntawm cookware).
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Ib qho kev sib npaug ntawm lub zog thiab hardness
Lub zog tensile ntawm titanium alloys feem ntau yog ib txwm nyob nruab nrab ntawm 900 mpa, tab sis nws lub zog tshwj xeeb (lub zog / ceev) yog 1.8 zaug siab dua. Qhov no txhais tau tias titanium alloys tuaj yeem ris lub nra hnyav dua rau qhov hnyav tib yam, muaj tus yam ntxwv zoo ib yam li cov khoom siv kis las ntawv siab. Txawm li cas los xij, titanium alloys muaj qis dua hardness (brinell hardness 250-350 hb) tshaj li quenched 440c stainless hlau tsis muaj zog hnav tsis kam. Carburizing lossis txheej txheej txheej yog xav tau los txhim kho kom tau npuaj.
Stainless hlau nthuav tawm cov cuab yeej siv hluav taws xob polarized: antenitic stainless hlau (xws li 304) muaj lub zog zoo tab sis qis dua lub zog; Martensitic stainless hlau tuaj yeem ua tiav ultra-siab hardness los ntawm kev kho cua sov thiab siv feem ntau siv hauv cov cuab yeej thiab pwm. Cov versatility no tso cai rau nws los npog ntau yam kev xav tau, los ntawm txhua hnub tableware mus rau kev siv riam.
Corrosion Kuj: Qhov kawg kuaj hauv Marine thiab Chemical Industries
Titanium alloys muaj chaw nyob ze-corrosion tsis kam. Zaj duab xis ntom xim ntom ntom (ti₂) tsim rau nws cov nplaim dej tuaj yeem tiv thaiv muaj zog corrosive media xws li seasater, chlor-alkali, thiab nitric acid. Tom qab nuclear submarine saws titanium alloy rau nws lub siab hull, nws cov kev pabcuam lub neej tau txuas mus rau 30 xyoo, deb tshaj li 10-15 xyoo ntawm stainless hlau. Hauv kev lag luam tshuaj, Titanium Reactors hloov cov hlau tsis muaj zog tau muaj ntau cov khoom siv ua neej li tsib zaug thiab txo tus nqi kho.
The corrosion resistance of stainless steel depends on composition control. 304 stainless steel, by adding 18% chromium and 8% nickel to form a passivation film, can resist weak corrosive environments such as the atmosphere and water vapor. 316 stainless steel, with an additional 2% molybdenum, significantly improves its resistance to pitting corrosion, becoming the standard bolt material for offshore oil platforms. However, in strong acid environments such as sulfuric acid (concentration >15%) thiab hydrochloric acid, stainless hlau tseem yuav tsum tau cov txheej txheem lossis kev tiv thaiv kev tua fij.
Shaanxi Haibowell Hlau Khoom Siv Technology Co., Ltd.: Lub Cav Innoveation rau cov ntaub ntawv hlau
Nyob rau hauv nthwv dej tshiab thev naus laus zis hauv cov ntaub ntawv hlau, Shaanxi Haib Kev Tsim Kho Cov Khoom Siv - Raws li cov khoom siv hluav taws xob, muab cov khoom siv tshuaj lom neeg, khoom siv kho mob, thiab lwm thaj chaw. Kev vam khom rau qib siab melting melting thiab precision dov thev naus laus zis, lub tuam txhab tuaj yeem tsim cov titan-high-zog stainless hlau tuav nrog tensile muaj zog txog 1500MPA. Nws cov khoom tau muab ntawv pov thawj los ntawm ISO 9001 kev tswj hwm kev tswj hwm zoo thiab tau siv dav hauv cov khoom lag luam siab xws li cov iav tsheb ua lag luam thiab ua haujlwm siab rau kev sib sib zog nqus-hiav txwv presces. Nrog rau "Cov Khoom Siv Kev Ua Haujlwm Zoo" raws li nws txoj haujlwm, muab cov khoom siv hauv ntiaj teb no thiab cov kev pabcuam thoob ntiaj teb nrog rau kev xaiv cov khoom siv los ntawm cov khoom ua tiav.
