Frequently Asked Questions
Q1: What are the main differences between GR2 and GR5 titanium bars?
GR2 is pure titanium (≥99.6%) offering high ductility, easy processing, and excellent corrosion resistance for low-load scenarios. GR5 is a titanium alloy (Ti-6Al-4V) providing high tensile strength (895MPa), fatigue resistance, and high temperature tolerance, making it ideal for high-load and harsh environments.
Q2: In what applications should I choose GR2 Titanium Square or Hexagonal Bars?
GR2 bars are perfect for low-load applications requiring high formability or resistance to mild corrosion. Typical examples include marine guardrail supports, freshwater filter bolts, juicer mixer shafts, food sterilizer fixing pins, outdoor furniture brackets, and gardening tool handles.
Q3: Why are GR5 titanium bars preferred for harsh industrial environments?
GR5 titanium bars offer high strength (895MPa), fatigue resistance, and can withstand high temperatures up to 400℃ as well as strong acid and oil-gas corrosion. This makes them ideal for demanding industries like aerospace, aviation, and petroleum.
Q4: Are GR2 titanium special-shaped bars safe for food processing equipment?
Yes. GR2 titanium special-shaped bars meet FDA hygiene standards. They are commonly used in the food industry to process components like mixer shafts for juicers and fixing pins for can sterilizers due to their non-toxic and corrosion-resistant properties.
Q5: What specific roles do GR5 titanium bars play in the petrochemical industry?
In the petrochemical sector, GR5 square bars are used to manufacture drive shafts for drilling platforms, and GR5 hexagonal bars are used for downhole valve bolts. They are selected for their ability to resist oil-gas corrosion and withstand high temperatures up to 300℃.
