Frequently Asked Questions
What is the main difference between GR2 and GR5 titanium rectangular/square tubes?
GR2 is commercially pure titanium (≥99.6% Ti) which offers excellent ductility, ease of welding, and moderate strength (345MPa). GR5 is an alpha-beta titanium alloy (Ti-6Al-4V) providing significantly higher tensile strength (895MPa) and excellent fatigue resistance, making it suitable for high-load applications.
Are GR2 titanium square tubes safe for food processing machinery?
Yes, GR2 titanium square tubes conform to hygiene standards and offer excellent corrosion resistance against food acids and alkalis. They are widely used for structural frames in food conveyor equipment and beverage filling machines.
What temperature limits can GR5 titanium rectangular tubes withstand?
GR5 titanium rectangular tubes feature exceptional high-temperature resistance, performing reliably in environments below 400℃, including downhole oil-gas transmission environments up to 300℃.
Why should I choose GR2 titanium for marine applications?
GR2 titanium is highly resistant to seawater and atmospheric corrosion, making it cost-effective and highly durable for marine light industry applications like handrails, guardrail frames, and deck structural supports.
Which grade is better for oil drilling and petrochemical platforms?
GR5 titanium is preferred for petrochemical platforms due to its high strength, high-temperature resistance, and superior resistance to acid, alkali, and oil-gas corrosion in harsh industrial environments.
