### Titanium CP Grade 2: Properties, Applications, and Specifications
Titanium CP Grade 2 is a versatile alloy renowned for its excellent strength-to-weight ratio and superior corrosion resistance, making it a go-to choice across numerous industries. Known for its lightness, Grade 2 titanium is particularly well-suited for demanding applications where weight reduction is crucial, such as in aerospace and medical fields. It also excels in harsh environments like marine settings, chemical processing plants, and desalination facilities. Common applications include oil and gas equipment, pressure vessels, heat exchangers, piping systems, and various industrial components. Grade 2 titanium can operate continuously at temperatures up to 800°F and handle occasional peaks up to 1000°F.
#### Corrosion Resistance
One of the standout features of Grade 2 titanium is its exceptional corrosion resistance. This property stems from the naturally occurring oxide film that forms on its surface when exposed to oxygen. This film acts as a robust barrier against corrosion in oxidizing, neutral, and mildly reducing environments. Additionally, Grade 2 titanium demonstrates impressive resistance to seawater and marine atmospheres, making it ideal for maritime applications. While all commercially pure (C.P.) titanium grades exhibit similar corrosion resistance, their mechanical properties vary depending on the levels of oxygen and iron present. Grade 2 titanium is highly resistant to moisture-laden chlorides, metallic chlorides, nitric acid, and organic acids, ensuring its reliability in challenging conditions.
#### Manufacturing and Formability
Grade 2 titanium is remarkably ductile, allowing it to be easily cold-formed. To avoid issues during cold forming, thinner materials (less than 0.070 inches) should employ a minimum bend radius of 2T, whereas thicker materials require a radius of 2.5T. The alloy is also straightforward to machine, heat treat, and weld. Hot working should occur within a temperature range of 400°F to 600°F. Stress relief treatments involve heating the material to temperatures between 900°F and 1100°F, followed by forced ventilation or slow cooling. For annealing, temperatures typically fall between 1200°F and 1400°F, held for 6 minutes to 2 hours, then cooled in air.
Welding Grade 2 titanium can be done using techniques such as MIG and TIG. Inert gas shielding is critical to prevent oxygen contamination, which could lead to brittleness. A mix of argon and helium is often recommended, though it’s advisable to test the specific shielding gas before proceeding. Neither preheating nor post-weld heat treatment is necessary.
