TA1 (GR1) Titanium yeeb nkab yog dab tsi?
May 14, 2026
1. Qib Background: TA1, TA2, TA3
Muaj ntshiab titanium muab faib ua TA1, TA2 thiab TA3 raws li impurity cov ntsiab lus. Cov ntsiab lus interstitial (feem ntau yog oxygen thiab hlau) nce los ntawm TA1 mus rau TA3, yog li lub zog thiab hardness nce nyob rau hauv qhov kev txiav txim thaum plasticity thiab toughness txo. TA1 haum rau kev tsim thiab sib sib zog nqus- kos duab; TA2 yog qhov siv dav tshaj plaws rau cov khoom sib npaug; TA3 raug xaiv kom muaj zog dua. Hauv Teb Chaws Asmeskas, GR1 (UNS R50250) sib raug rau ASTM B338/B861 qib 1 thiab rau GB/T 3624/3625 TA1.
2. Cov khoom tseem ceeb
- Tsawg ceev - 4.51 g/cm³.
- Zoo corrosion kuj - superior rau 316L stainless hlau nyob rau hauv seawater thiab chloride ib puag ncig; zoo nyob rau hauv huab cua, ntub chlorine, oxidising, nruab nrab thiab tsis muaj zog txo cov xov xwm.
- High ductility - yam tsawg kawg nkaus 24% elongation.
- Zoo weldability - GTAW nrog ERTi-1 muab tub lim yog tsim tau zoo.
- Cov cua sov tsis zoo - rau kev pabcuam tshuaj, kev ua haujlwm kub yuav tsum nyob qis dua li 360 degree; saum toj no, oxidation accelerates thiab lub zog degrades.
