GR12 Titanium Tube (Ti-0.3Mo-0.8Ni) – High-Performance Corrosion-Resistant Tubing
Product Overview
GR12 Titanium Tubes (UNS R53400, ASTM B338 Grade 12) are premium corrosion-resistant titanium alloy tubes designed for extreme environments in chemical processing, marine, and oil & gas industries. With superior crevice corrosion resistance and excellent weldability, GR12 outperforms pure titanium (Gr2) in aggressive media like hot chlorides, acids, and seawater.
✅ Key Advantages for Buyers:
✔ Best-in-class corrosion resistance (better than Gr2 & Gr7)
✔ Higher strength than pure titanium (Gr2)
✔ Easier welding & fabrication vs. Gr7/Gr11
✔ Cost-effective alternative to nickel alloys

| Pharmaceutical | CIP/SIP systems | Non-contaminating |
GR12 vs. Alternatives (Buyer’s Decision Guide)
| Alloy | Corrosion Resistance | Strength | Cost | Best For |
|---|---|---|---|---|
| GR12 | ★★★★★ (HCl, seawater) | ★★★★ | $$$ | Cost-effective harsh media |
| Gr2 | ★★★ (mild acids) | ★★ | $$ | General-purpose |
| Gr7 | ★★★★★ (HCl, oxidizers) | ★★★ | Extreme oxidizers | |
| Hastelloy | ★★★★★ | ★★★★ | $ | Hot sulfuric acid |
💡 Procurement Tip: GR12 cuts costs by 30–50% vs. Gr7/Hastelloy where oxidizers aren’t dominant.
FAQs
Q: Is GR12 titanium tube weldable?
A: Yes! GR12 welds more easily than Gr7 using standard TIG/GTAW. No post-weld annealing required.
Q: Can GR12 replace Gr7 in HCl service?
A: For <10% HCl at <60°C, GR12 is a cost-effective alternative. For stronger oxidizers, Gr7 is safer.
Q: What’s the price range for GR12 tubes?
A: Contact us for real-time quotes.
