Aircraft manufacturers choose our titanium alloy steel pipes-primarily Ti-6Al-4V and Ti-3Al-2.5V. For example, our workhorse Ti-6Al-4V boasts a tensile strength of 895 MPa, comparable to heavy-duty steel pipe, yet 40% lighter.
Tested according to ASTM G31, it demonstrates significantly higher strength than stainless steel in coastal environments. It also offers excellent high-temperature resistance, retaining 90% of its room-temperature strength at 300°C, making it a top choice for wholesalers supplying the aerospace and chemical processing industries.
We offer two main surface treatments: pickled (per ASTM A967) to remove any oxides, leaving a clean surface ready for welding, and polished (Ra 0.8μm max, as per ASTM B46.1) for applications where appearance matters.
Our cutting service can handle lengths from 1m to 6m with a tolerance of ±1mm, using precision saws that leave smooth edges. We also do threading (NPT or BSP, following ASTM F138) for easy installation, and each pipe gets a hydrostatic test (at 1.5 times the working pressure, per ASTM B861) to ensure no leaks.
We use vacuum arc remelting (VAR) technology, which keeps impurity levels low-oxygen content is controlled
We keep 500-800 tons in stock , covering common sizes from 1/2 inch to 8 inches in diameter and wall thicknesses from 0.8mm to 10mm. The stock list updates in real time on our website, and for in-stock items.
If you order more than 50 tons, you'll get a 6% discount, plus free pickling and 25% of the sea freight covered to ports like Rotterdam or Houston (thanks to our long-term deals with shipping companies).
Here's our promise: If any Titanium Alloy Steel Pipe doesn't meet ASTM B338 mechanical standards or has corrosion issues normal use, we'll replace it within a week and cover all the shipping costs. We also lock the price for 45 days on bulk orders, so you won't have to worry about sudden price hikes.
Titanium alloys (key grades): Ti-6Al-4V (Grade 5, most common): 6% Al, 4% V, balance Ti; Ti-3Al-2.5V (Grade 9): 3% Al, 2.5% V (for tubing); Ti-12Mo-6Zr-2Fe (Grade 12): high corrosion resistance
Mechanical Properties
Tensile Strength: Ti-6Al-4V: ≥895 MPa; Ti-3Al-2.5V: ≥655 MPa
Yield Strength: Ti-6Al-4V: ≥825 MPa; Ti-3Al-2.5V: ≥550 MPa
Elongation: ≥10% (Ti-6Al-4V); ≥15% (Ti-3Al-2.5V)
Density: ~4.43 g/cm³ (lightweight)
Corrosion Resistance
Excellent resistance to: Seawater, brines, and marine environments (no pitting/corrosion even long-term); Oxidizing acids (nitric acid) and chloride solutions; High-purity water and wet chlorine; Stress corrosion cracking (SCC) in most environments
Temperature Resistance
Service range: -270°C to 400°C (-454°F to 752°F) (Ti-6Al-4V); retains strength at low temps and resists creep at moderate highs; limited above 400°C (oxidation risk)
Form & Dimensions
Type: Seamless (high pressure) or welded (thin-walled)
Outer Diameter: 6mm to 600mm (0.25" to 24"); Wall Thickness: 0.5mm to 20mm
Length: Up to 12m (40ft); custom cuts available
Standards Compliance
ASTM B338 (seamless titanium pipes); ASTM B861 (welded); ASME SB338 (boiler/pressure vessel code); ISO 13374 (titanium tubing for industrial use)
Fabrication
Weldable via TIG (argon-shielded to prevent oxidation); machinable (low thermal conductivity requires slow speeds); formable by bending/rolling (annealed state optimal)
Key Applications
Marine: Seawater cooling systems, submarine piping
Chemical Processing: Chloride/acid transport, high-purity reactors
Aerospace: Aircraft hydraulic lines, engine components (lightweight)
Medical: Pharmaceutical equipment, high-purity fluid lines
Desalination: Reverse osmosis (RO) systems
Key Advantages
Ultra-lightweight (1/2 the weight of steel, 2/3 of nickel alloys) – reduces system load
Superior corrosion resistance in harsh environments (outperforms stainless steel in seawater/chlorides)
High strength-to-weight ratio; good fatigue resistance
Biocompatible (safe for medical/pharmaceutical use)
