FAQ
Q1: How does TA10 differ from TA2 or TC4 titanium bars?
A: TA10 (Grade 12) adds 0.3% Mo and 0.8% Ni for superior resistance to reducing acids (H₂SO₄, HCl), while TA2/TC4 excel in oxidizing environments and high-strength applications.
Q2: What machining parameters prevent galling?
A: Use carbide tools at cutting speeds ≤50 m/min with high-pressure coolant (≥50 bar) to minimize heat buildup.
Q3: Are bars certified for sour service in oil & gas?
Full compliance includes:
- NACE MR0175/ISO 15156-3
- ASTM G48 Method A (crevice corrosion testing)
- DNV-GL Offshore Standard
Q4: What’s the minimum order quantity (MOQ)?
Standard stock: 1000 kg MOQ.
Custom sizes/surface finishes: 5 tons MOQ (lead time 30 days).
