Jan 15, 2026
GR5 titanium yog dab tsi?
Ti-6Al-4V (Qib 5), muab faib ua alpha-beta alloy, yog qhov siv dav tshaj plaws ntawm lub zog siab titanium alloys. Cov hlau sib xyaw ua ke nws lub zog zoo txhua yam thiab qhov ntom ntom (4.42 kg / dm³) nrog rau kev tiv thaiv corrosion zoo hauv ntau cov xov xwm.
Qib 5 titanium yog tag nrho cov cua sov kho tau (kev kho cua sov kho ntxiv rau kev laus) hauv ntu txog li 25 hli thiab tuaj yeem ua haujlwm txog li 400 degree. Ti-6Al-4V ELI (Qib 23) muaj qhov txo cov pa oxygen (0.13% max.) piv nrog Qib 5. Qhov no confers txhim kho ductility thiab pob txha toughness nrog qee qhov txo cov neeg kho tshuab lub zog. Kev siv suav nrog cov pob txha tseem ceeb ntawm cov qauv hauv cov huab cua thiab rau cov tubular offshore.

Corrosion Resistance
Qib 5 titanium muaj kev tiv thaiv zoo rau ntau qhov chaw marine thiab offshore roj & roj ib puag ncig. Titanium thiab nws cov alloys tiv taus ntau yam ntawm cov kua qaub uas tiv taus oxidising acids, muaj txiaj ntsig zoo los txo cov kua qaub thiab muab kev tiv thaiv zoo rau feem ntau cov organic acids qis dua thiab kub. Titanium yuav tsum tsis txhob siv nrog liab fuming nitric acid thiab yog sai heev los ntawm hydrofluoric acid.
Qhov sib ntxiv ntawm 0.05% palladium (qib 24), 0.1% ruthenium (qib 29) lossis 0.05% palladium thiab 0.5% npib tsib xee (qib 25) ua rau muaj kev tiv thaiv corrosion hauv kev txo cov acid chloride thiab qaub ib puag ncig, nce qhov kub thiab txias kom zoo tshaj 200 degree.
