Characteristics of CP Grade 2

The corrosion resistance of CP Grade 2 is based on the presence of a stable, continuous, tightly adherent oxide layer. This layer forms spontaneously and immediately upon exposure to oxygen. If damaged, it is able to readily reform as long as there is a source of oxygen in the environment. CP Grade 2 has relatively low impurity levels and is widely used due to its capability to perform well in many corrosion-critical applications such as marine environments and chemical processing. In seawater, this grade is fully resistant to corrosion at temperatures up to 600°F (315°C). This grade is fully resistant to stress-corrosion cracking in aqueous solutions and is largely immune to stress-corrosion cracking in general. 

Working with CP Grade 2

CP Grade 2 can be hot worked, cold worked, and machined. When hot working, CP Grade 2 can be processed using conventional techniques such as hot rolling, forging, and hot pressing. Temperatures for initial roughing may be as high as 50-100°F (30-50°C) above the beta transus, and temperatures for finish processing typically range from 1500°F (815°C) to about 1650°F (900°C). CP Grade 2 has good ductility and can be formed at room temperature by various standard methods, including bending, stretch forming, heading, stamping, and drawing. This grade work hardens fairly rapidly, which is a limitation in some operations, such as cold drawing. The machining characteristics of CP Grade 2 are similar to those of austenitic stainless steels. In general, low cutting speeds, heavy feed rates, and copious amounts of cutting fluid are recommended when working with CP Grade 2. Because of the strong tendency of titanium to gall and smear, feeding should never be stopped while the tool and workpiece are in moving contact.
