Product Description
ASTM SB337 SB338 Gr1 Gr2 Titanium Exhaust Pipes TA0 TA1 TA2 TA9 TA10 BT1-00 BT1-0
Product Overview
TA2 titanium alloy tube is an industrial pure titanium product with titanium content ≥99.2%, strictly complying with international and domestic standards. Compared with TA1, it has higher strength while retaining the inherent advantages of pure titanium such as lightweight, corrosion resistance, good biocompatibility and excellent processability.
Product Types: Seamless Tube (mainstream), Welded Tube
Outer Diameter: Φ3mm - Φ508mm (seamless); Φ10mm - Φ1000mm (welded), customizable
Wall Thickness: 0.3mm - 20mm (seamless); 0.3mm - 15mm (welded)
Length: 1m - 12m, fixed length (3m, 6m, 9m) or random length available
Surface Condition: Pickling, Bright Annealing, Polished, Sandblasted
Tolerance Precision: Outer diameter ±0.02-0.5mm; Wall thickness ±0.02-0.3mm; Straightness ≤1mm/m
Technical Specifications
Chemical Composition (wt.%)
| Element | Content Range | Function & Description |
|---|---|---|
| Ti (Titanium) | ≥99.2% | Matrix element, determining basic corrosion resistance and mechanical properties |
| O (Oxygen) | ≤0.25% | Interstitial element, producing solid solution strengthening effect |
| Fe (Iron) | ≤0.30% | Impurity element, properly increasing content can enhance strength |
| C (Carbon) | ≤0.08% | Impurity element, excessive content reduces plasticity |
| N (Nitrogen) | ≤0.03% | Harmful impurity, excessive content increases hardness and reduces toughness |
| H (Hydrogen) | ≤0.015% | Harmful impurity, strictly controlled to avoid hydrogen embrittlement |
Note: Medical-grade TA2 titanium tubes can be customized with stricter impurity control to meet ASTM F67 standard requirements.
Mechanical Properties (Annealed State, Room Temperature)
| Performance Index | Unit | GB/T 3624.1 Requirement | ASTM B338 Requirement | Description |
|---|---|---|---|---|
| Tensile Strength (σb) | MPa | ≥450 | ≥440 | Significantly higher than TA1, suitable for structural parts |
| Yield Strength (σs) | MPa | ≥275 | ≥320 | Good load-bearing capacity, not easy to deform |
| Elongation (δ5) | % | ≥20 | ≥20 | Good plasticity, suitable for bending and welding |
| Hardness (HB) | HB | ≤190 | ≤180 | Moderate hardness, easy to process |
| Density | g/cm³ | 4.51 | 4.51 | Lightweight, 40% lighter than stainless steel |
Note: The strength of cold-worked TA2 titanium tube can be increased to ≥600MPa, and performance can be adjusted through annealing treatment.
