Titanium Grades 2 and 7

Titanium Grade 2 (Commercially Pure Titanium)

Titanium Grade 2 is one of the most widely used forms of commercially pure titanium, offering an excellent balance of corrosion resistance, strength, and workability.

Chemical Composition: Approximately 99.2% high-purity titanium, with small amounts of oxygen, iron, and nitrogen.

Key Features:

• Outstanding corrosion resistance in marine and chemical environments
• Lighter than steel, reducing overall system weight
• Moderate tensile strength compared to other pure titanium grades
• Good formability, weldability, and machinability

Typical Applications:

• Corrosion-resistant linings and coatings for steel equipment
• Manufacturing of tanks, vessels, and pipelines for corrosive fluids
• Combined with stainless steel to enhance corrosion resistance and lower weight
• Components requiring moderate strength with high durability in harsh conditions

Titanium Grade 7

Titanium Grade 7 shares many properties with Grade 2 but includes a small amount of palladium (0.12–0.25%), giving it superior resistance to more aggressive environments.

Key Features:

• Enhanced corrosion resistance, especially in acidic and chlorinated conditions
• Excellent resistance to pitting, crevice, and stress corrosion
• Maintains high workability and weldability

Typical Applications:

• Ideal for extremely corrosive environments in chemical, petrochemical, and marine industries
• Protective linings and coatings for equipment handling acids and harsh chemicals
• Increases the lifespan and durability of steel equipment in aggressive conditions
• Preferred over Grade 2 where maximum corrosion resistance is required
