Dab tsi yog Qhov Zoo Ntawm Gr2 Titanium Tubing?

Dab tsi yog qhov zoo ntawm Gr2 titanium raj:

1. Titanium raj muaj lub zog tshwj xeeb. Titanium alloy ntom yog feem ntau nyob ib ncig ntawm 4.5g / cm3, tsuas yog 60% ntawm cov hlau, lub zog ntawm titanium ntshiab yog ze rau lub zog ntawm cov hlau zoo tib yam, qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov hlau alloy steel. Yog li ntawd, lub zog tshwj xeeb ntawm titanium alloy (lub zog / ntom) yog ntau dua li lwm cov khoom siv hlau, tuaj yeem tsim tau lub zog siab, zoo rigidity, lub teeb qhov hnyav thiab cov khoom siv. Tam sim no, lub dav hlau cav Cheebtsam, pob txha, tawv nqaij, fasteners thiab tsaws iav, thiab lwm yam yog siv titanium alloy.

2. Titanium tubes muaj thermal zog. Kev siv qhov kub thiab txias tshaj li cov aluminium alloy ob peb puas degrees siab dua nyob rau hauv nruab nrab qhov kub thiab txias tseem tuaj yeem tuav lub zog uas yuav tsum tau muaj, tuaj yeem nyob rau hauv qhov kub thiab txias ntawm 450-500 degree kev ua haujlwm ntev ntawm ob hom titanium alloys nyob rau hauv qhov ntau. ntawm 150 degree mus rau 500 degree tseem muaj lub zog tshwj xeeb, thiab aluminium alloy ntawm 150 degree dua li lub zog ntawm qhov pom tseeb poob. Kev ua haujlwm kub ntawm titanium alloy tuaj yeem ncav cuag 500 degree, aluminium alloy yog qis dua 200 degree.

3. Titanium raj muaj corrosion kuj zoo. Titanium alloy nyob rau hauv cov huab cua ntub thiab seawater media ua hauj lwm, nws cov corrosion kuj zoo dua li cov hlau tsis muaj steel; pitting, acid corrosion, kev nyuaj siab corrosion kuj muaj zog tshwj xeeb; alkali, chloride, chlorine organic khoom, nitric acid, sulfuric acid, thiab lwm yam muaj zoo heev corrosion kuj. Tab sis titanium muaj qhov txo qis oxygen thiab chromium ntsev media corrosion kuj tsis zoo.

4. Titanium raj muaj qhov ua tau zoo ntawm qhov kub thiab txias. Titanium alloy nyob rau hauv qis kub thiab ultra-tsawg kub, tseem tuaj yeem tswj nws cov khoom siv kho tshuab. Kev ua tau zoo ntawm qhov kub thiab txias, qhov sib txawv yog qhov tsawg heev titanium alloy, xws li TA7, nyob rau hauv -253 degree kuj tseem tuaj yeem tswj tau qee yam ntawm plasticity. Yog li ntawd, titanium alloy kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob qis.

5. Cov tshuaj ua haujlwm ntawm titanium raj yog loj. Titanium cov tshuaj ua haujlwm, thiab cov huab cua O, N, H, CO, CO2, dej vapor, ammonia thiab lwm yam tshuaj muaj zog. Cov ntsiab lus carbon ntau dua 0.2%, yuav tsim ib qho nyuaj TiC hauv titanium alloys; kub dua, thiab lub luag hauj lwm ntawm N yuav kuj tsim ib tug nyuaj nto txheej ntawm TiN; saum toj no 600 degree, titanium absorbs oxygen los tsim ib txheej txheej hardness siab; hydrogen cov ntsiab lus nce, tab sis kuj tsim ntawm embrittlement txheej. Titanium cov tshuaj affinity kuj loj, yooj yim los tsim adhesion phenomenon nrog kev sib txhuam nto.

6. Titanium tubing muaj cov thermal conductivity me me thiab cov qauv me me ntawm elasticity. Titanium lub thermal conductivity yog me me, me me modulus ntawm elasticity ntawm titanium alloy modulus ntawm elasticity yog hais txog 1/2 ntawm cov hlau, yog li nws rigidity tsis zoo, yooj yim rau deform, tsis haum rau zus tau tej cov slender rods thiab nyias-walled qhov chaw, txiav lub machining nto ntawm lub rebound yog loj heev, txog 2-3 lub sij hawm lub stainless hlau, uas ua rau ntse txhuam, adhesion, bonding hnav ntawm lub cuab tam tom qab riam nto.
