TITANIUM GRADE 2

Back To Alloys
UNS - R50400

Titanium Grades 2 is one of the most important grade utilized for condenser tubing, Heat exchangers and offshore oil installation water pipe lines, bleaching plants in the paper industry.

This grade can be utilized for the parts requiring strength up to 400°F as well as oxidation resistance to 600°F. Titanium Grade 2 is commercially pure which is slightly stronger than Grade 1 but equitably corrosion resistant against most applications.

Characteristics

• Moderate Strength Titanium
• Excellent Cold Formability
• Excellent Weldability
• Excellent Resistance to High Oxidation

Applications

• Orthopaedic applications, such as implants and prosthesis
• Airframe and aircraft engine parts
• Marine chemical parts
• Condenser tubing
• Heat exchangers

Machining

As a family, titanium and its alloys have built a persona as a nightmare to machine. This is just not the situation. Experienced operators have compared its qualities to those found in 316 stainless steels. Recommended practice includes high coolant flow (to offset the material's low thermal conductivity), slow speeds and generally high feed rates. Tooling should be tungsten carbide designations C1-C4 or cobalt type high speed tools.

Welding

Titanium Grade 2 may be welded by a wide assortment of standard fusion and solid-state processes, in spite of its chemical reactivity normally requires uncommon measures and process.

Forming

Forming might be hot or cold shaped by utilizing hydro press, power brake, stretch or drop hammer techniques. Forming is same in attributes to 300 series stainless steels.

Hot Working

Both the spring back and required forming forces are reduced by hot forming and will increase the overall ductility of the material.

Cold Working

The cold work qualities of this material are same as that of a moderately tempered austenitic stainless steel. In numerous cold forming operations, intermediate stress relief is recommended to prevent tearing or other material damage. Post-work annealing is required to reattain optimum performance qualities.

Heat Treatment

Not hardenable by heat treatment.

Annealing

Heat to 704 C (1300 F),hold for 2 hours follow by air cooling. For intermediate stress relieving, heat to 482 F(900 C) and hold for 45 minutes.

Forging

Roughing operations can begin at 899 C (1650 F),while finishing should be performed at 843 C(1550 F).

Other Physical Props

Beta Transus (F +/- 25) 167
