Titanium cov ntaub ntawv classifications
Titanium cov ntaub ntawv ntawm qib 1-4 yog unalloyed thiab suav hais tias ua lag luam li ntshiab los yog "CP." Feem ntau hais lus, lub zog tensile thiab yield zog nce nrog cov lej ntawm cov qib no.
Paub li Ti6Al4V, Ti-6Al-4V, los yog Ti 6-4, Gr5 yog cov feem ntau siv alloy vim nws tshwj xeeb lub cev thiab tshuaj zog, uas muaj ib tug tshuaj muaj pes tsawg leeg ntawm 6% Aluminium, 4% Vanadium, 0.25% (siab tshaj) Hlau, 0.2% (siab tshaj) Oxygen, thiab tus so yog Titanium.
Gr7 muaj 0.12% rau 0.25% Palladium. Qhov me me ntawm Palladium muab lawv txhim kho crevice corrosion kuj ntawm qhov kub thiab txias thiab pH siab.
Gr9 muaj 3.0% Aluminium thiab 2.5% Vanadium. Lawv feem ntau siv nyob rau hauv dav hlau tubing rau hydraulics thiab hauv cov khoom kis las.
Qib 12 muaj 0.3% Molybdenum thiab 0.8% Nickel.
Qib 23 muaj 6% Aluminium, 4% Vanadium, thiab 0.13% (siab tshaj) Oxygen.
