Regarding industrial applications requiring high strength, durability, and corrosion resistance, titanium is a popular material of choice. Among the various grades of titanium available in the market, grade 2 is one of the most commonly used due to its excellent balance of properties and cost-effectiveness. This blog post examines titanium grade 2 flanges and explores their composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance.
Titanium Grade 2 Flanges Composition
Titanium grade 2 is a commercially pure titanium alloy that contains approximately 98.5% of titanium, along with small amounts of iron, oxygen, carbon, and nitrogen. This high-purity grade of titanium is highly resistant to corrosion in various environments and is also bio-compatible, making it suitable for medical implants and equipment.

Titanium Grade 2 Flanges Uses
Titanium Gr 2 Socket Weld Flanges are commonly used in various industries such as aerospace, marine, chemical, and petrochemical. They often connect pipes, valves, and other equipment in high-corrosive environments. Due to their biocompatibility and corrosion resistance, they are also used in medical equipment, such as surgical implants and prosthetics.
Titanium Grade 2 Flanges Heat Treatment
Titanium Gr 2 Blind Flanges can be heat-treated to improve its mechanical properties. Annealing at 760-788°C can improve flexibility and toughness, while solution treatment at 870-925°C followed by water quenching can improve strength and hardness.
Titanium Grade 2 Flanges Corrosion Resistance
Titanium grade 2 is highly corrosion-resistant in various environments, including seawater, oxidizing acids, chlorides, and alkaline solutions. It forms a passive oxide layer on its surface that protects against further corrosion.
Conclusion
Titanium grade 2 flanges offer an excellent balance of properties that make them suitable for various industrial applications that require high strength, lightweight, and corrosion resistance. Their composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance are some of the key factors that make them a popular material of choice. If you’re looking for a reliable and cost-effective material that can withstand harsh environments, titanium grade 2 flanges might be what you need.
