Frequently Asked Questions
Which Titanium grade is most commonly used for flanges?
Grade 2 is the most widely used due to its balance of strength, corrosion resistance, and weldability.
What’s the difference between Grade 2 and Grade 5 Titanium flanges?
Grade 2 is commercially pure titanium with excellent corrosion resistance, while Grade 5 (Ti-6Al-4V) offers much higher strength, making it ideal for aerospace and offshore industries.
Are Titanium flanges suitable for seawater applications?
Yes, especially Grade 2, Grade 7, and Grade 12 Titanium flanges are highly resistant to seawater and brine, making them perfect for marine and desalination plants.
