TA2 (อีไล) GR2 Titanium Alloy

Industrial Pure Titanium TA2

Industrial pure titanium is classified into three grades based on impurity content: TA1, TA2, and TA3. The interstitial impurity elements in these grades increase progressively, leading to a corresponding increase in mechanical strength and hardness, while plasticity and toughness decrease.

• TA1: Best suited for applications requiring good forming performance.
• TA2: Most commonly used in industry due to its moderate corrosion resistance and balanced mechanical properties.
• TA3: Chosen for applications requiring higher wear resistance and strength.

Correspondence to UNS Grades

• TA1: Corresponds to UNS Grade 1 (Gr1)
• TA2: Corresponds to UNS Grade 2 (Gr2)
• TA3: Corresponds to UNS Grade 3 (Gr3)

Low-Temperature Performance

TA1 and TA2 with the following impurity levels exhibit excellent low-temperature toughness and high low-temperature strength, making them suitable for use as low-temperature structural materials at temperatures below -253°C:

• Iron (เฟ): 0.095%
• Oxygen (โอ): 0.08%
• Hydrogen (ชม): 0.0009%
• Nitrogen (เอ็น): 0.0062%
