TA10 Titanium Alloy Coil (Ti-0.3Mo-0.8Ni, Grade 12)

Engineered for extreme chemical processing, marine, and offshore applications, TA10 titanium alloy coil (Grade 12) delivers unmatched resistance to reducing acids, chlorides, and crevice corrosion in continuous fabrication processes. With a unique titanium-molybdenum-nickel alloy composition (Ti-99.5%, Mo-0.3%, Ni-0.8%), it outperforms Grades 2 (TA2) and 5 (TC4) in sulfuric acid, hydrochloric acid, and seawater environments at elevated temperatures. Certified to ASTM B863, ASME SB-338, and NACE MR0175, TA10 coil offers 10x longer service life than 316L stainless steel in 15% H₂SO₄ at 80°C (176°F) while maintaining 40% lighter weight than steel and seamless cold-rolling capabilities.

FAQ

Q1: How does TA10 differ from TA2 or TC4 titanium coils?

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 welding methods prevent contamination?

A: Use GTAW (TIG) with ERTi-12 filler rod under argon shielding gas (dew point ≤-50°C) to avoid oxidation.

Q3: Are coils certified for sour service in oil & gas?
