What is the typical elongation of Grade 2 titanium

Grade 2 titanium typically has an elongation (ductility) of 20% to 30% in 50 mm (2-inch) gauge length at room temperature, as specified in standard specifications like ASTM B265 and ASME SB265. This high elongation value indicates excellent ductility and formability, making Grade 2 suitable for various forming operations such as bending, stamping, and deep drawing.

Yes, the strength of Grade 2 titanium does decrease as temperature increases. Like most metallic materials, commercially pure titanium (Grade 2) exhibits a reduction in tensile strength, yield strength, and hardness at elevated temperatures, while its ductility (elongation) generally increases.

At moderate temperatures (up to approximately 315°C / 600°F), the strength reduction is gradual. However, as the temperature rises beyond this range, the decrease in strength becomes more pronounced. This thermal softening effect is a key consideration for high-temperature applications, as it limits the maximum service temperature for load-bearing components made from Grade 2.

For applications requiring significant strength at high temperatures, titanium alloys (such as Grade 5 Ti-6Al-4V) are typically preferred over commercially pure Grade 2 titanium.
