Product catalog summary
Introduction
ATI offers corrosion-resistant titanium in plate, sheet, and strip forms. Known for its low density and high strength-to-weight ratio, titanium is ideal for corrosive environments, such as oxidizing chloride solutions and chlorine-based bleaches.

Typical Applications
  • Heat Transfer: Used in power plants and refineries for its resistance to seawater and polluted water.
  • DSA-Dimensional Stable Anodes: Efficient for chlorine production due to unique electrochemical properties.
  • Desalination: Cost-effective for desalination plants due to corrosion resistance.
  • Metal Extraction: Used in environmentally friendly hydrometallurgical processes.
  • Medical: Biocompatible for implants and surgical devices.
  • Hydrocarbon Processing: Resistant to hydrocarbons and stress corrosion cracking.
  • Marine Applications: Used in submarines and ship systems for its toughness and corrosion resistance.
  • Chemical Processing: Suitable for aggressive compounds.
  • Structural/Architectural: Increasingly used for its durability and aesthetic appeal.

Corrosion Resistance
  • General Corrosion: Resistant to a variety of environments but not suitable for pure oxygen service.
  • Crevice Corrosion: Excellent resistance, especially in unalloyed and palladium-alloyed grades.
  • Microbiologically Influenced Corrosion (MIC): Immune to MIC, controllable biofouling.
  • Galvanic Corrosion: Functions as a cathode, not affected by galvanic corrosion.
  • Stress Corrosion Cracking: Excellent resistance in hot chloride solutions.
  • Erosion Corrosion: Resistant to flow-induced corrosion.
  • Hydrogen Embrittlement: Susceptible under certain conditions, less so in low-strength grades.

Fabrication
  • Welding: Readily weldable with proper shielding; various welding techniques applicable.
  • Formability: Formable at room temperature; requires attention to bend radii, spring back, and lubrication.

Grades and Formability
Grades 1, 11, and 17 are the most formable, while Grade 4 is the least. Surface preparation is crucial to prevent defects during forming.

Chemical Composition and Mechanical Properties
Details on chemical composition and mechanical properties are provided, emphasizing typical values rather than specifications.

ATI 6-4™-2

Corrosion-Resistant Titanium Technical Data Sheet TYPICAL APPLICATIONS Heat Transfer A major industrial application for titanium is in heat transfer applications for which the cooling medium is seawater, brackish water or polluted water. Titanium condensers, shell and tube heat exchangers, and plate and frame heat exchangers are used extensively in power plants, refineries, air conditioning systems, chemical plants, offshore platforms, surface ships and submarines. Millions of feet of welded titanium tubing are in power plant condenser service, and there have been no reported failures due to...

ATI 6-4™-3

Corrosion-Resistant Titanium Technical Data Sheet not suitable for pure oxygen service. Titanium does not release any toxic ions into aqueous solutions, thus helping to prevent pollution. Crevice Corrosion ATI titanium has excellent resistance to crevice corrosion in salt solutions and generally outperforms stainless steels. Unalloyed titanium (grades 1, 2, 3, and 4) typically do not suffer crevice corrosion at temperatures below 80°C (175°F) at any pH. Palladium alloyed CP titanium (grades 7, 11, 16 and 17) are more resistant and typically do not suffer crevice corrosion at temperatures below...

ATI 6-4™-4

Corrosion-Resistant Titanium The various grades of ATI titanium exhibit differences in formability. Grades 1, 11 and 17 titanium, which are the softest and most ductile grades, exhibit the greatest formability. The slightly greater strengths of Grades 2, 7 and 16 titanium are still quite formable, but less so than Grades 1, 11 or 17. The higher strength of Grade 4 titanium makes it the least formable of the CP titanium alloys. Normally, titanium surfaces are acceptable for forming operations as received from the mill. Gouges and other surface marks introduced during handling should be removed...
