Frequently Asked Questions
What is the main difference between GR2 and GR5 titanium rectangular/square tubes?
GR2 is commercially pure titanium (≥99.6%) offering excellent formability, weldability, and corrosion resistance for low-load applications. GR5 is a titanium alloy (Ti-6Al-4V) providing significantly higher tensile strength (895MPa) and fatigue resistance, making it suitable for high-load and demanding structural applications.
What are the ideal application scenarios for GR2 titanium square tubes?
GR2 titanium tubes are ideal for low-load and mild corrosion environments. Key applications include marine light industry (marine handrails, guardrail frames, and deck structural supports) and the food processing industry (conveyor equipment frames and beverage filling machines) due to their seawater resistance and compliance with hygiene standards.
Can GR5 titanium rectangular tubes withstand high-temperature environments?
Yes, GR5 titanium rectangular and square tubes feature excellent high-temperature resistance (suitable for operation below 400℃). This makes them highly effective for harsh industrial environments, including downhole oil-gas transmission equipment and petrochemical pipeline structures.
Why is GR5 titanium preferred for high-load transmissions?
GR5 titanium (Ti-6Al-4V) has a very high tensile strength of 895MPa, which is more than double that of GR2. This exceptional strength-to-weight ratio and outstanding fatigue resistance make it the preferred material for high-strength structural requirements like aviation frames and racing car chassis.
Are these titanium tubes resistant to acids, alkalis, and seawater?
Yes. GR2 titanium tubes offer excellent corrosion resistance against fresh water, atmospheric elements, and food-grade acids/alkalis. GR5 titanium tubes offer superior resistance to harsh chemical substances, acid and alkali environments, and high-temperature oil-gas corrosion, making them ideal for offshore platforms and chemical processing.
