Titanium Sheet (GR1 & GR2, ASTM B265) – Complete Industrial Guide.
Explore how to select the right Titanium Sheet (ASTM B265 Gr1 & Gr2) for industrial applications. This guide covers properties, thickness, real-world applications, pricing factors, and how titanium compares to stainless steel and nickel alloys.
1. Introduction: Why Titanium Sheet Matters in Industry
Titanium sheet has become an essential material across multiple industrial sectors, from chemical processing and heat exchangers to seawater desalination and marine engineering. Its combination of exceptional corrosion resistance, high strength-to-weight ratio, and long service life makes it superior to traditional metals like stainless steel or nickel alloys.
Industrial engineers and buyers searching for “titanium sheet for heat exchanger”, “Gr2 Titanium Plate”, or “Astm B265 Titanium sheet” are typically looking for practical performance data, durability comparisons, and application guidance.
This guide will cover everything you need to know about titanium sheet, including grades, properties, thickness, surface finishes, production processes, industrial applications, pricing factors, common problems, and solutions.
2. Understanding Titanium Sheet
Titanium sheet refers to flat-rolled titanium materials, usually below 10 mm in thickness. It is widely used in environments where corrosion, weight, and durability are critical.
Key Advantages:
- Exceptional corrosion resistance (chlorides, oxidizing acids)
- High strength-to-weight ratio (lighter than steel, almost equivalent strength)
- Long lifecycle, reducing maintenance costs

| Iron | ≤0.20% | ≤0.30% |
| Nitrogen | ≤0.03% | ≤0.03% |
4.2 Mechanical Properties (ASTM B265)
| Property | Gr1 | Gr2 |
| Tensile Strength | ≥240 MPa | ≥345 MPa |
| Yield Strength | ≥170 MPa | ≥275 MPa |
| Elongation | ≥24% | ≥20% |
Selection Guide:
- Gr1:Softer, better for deep drawing and complex forming.
- Gr2:Stronger, suitable for general industrial use like heat exchangers, chemical reactors, and pressure vessels.

5. Key Properties of Titanium Sheet
5.1 Corrosion Resistance
Titanium forms a stable oxide layer (TiO₂), making it highly resistant to:
- Chloride-rich environments (seawater)
- Oxidizing acids (e.g., nitric acid)
- Industrial chemicals
Example Comparison (Industry Reference):
| Material | Seawater Lifespan |
| 316L Stainless Steel | 3–5 years |
| Titanium Gr2 | 15–20+ years |
This is why titanium is widely used in desalination plants and offshore equipment.
5.2 Strength-to-Weight Ratio
- Titanium density: ~4.51 g/cm³
- Stainless steel density: ~7.85 g/cm³
Titanium is ~40% lighter, yet maintains high strength.
5.3 Fabrication & Weldability
- Excellent weldability with inert gas shielding
- Cold forming is easier with Gr1

7.2 Thickness Tolerance (ASTM B265)
- Thin sheet: ±0.02 mmwith thickness 0.5-1.5mm
- Flatness critical for heat exchangers and chemical reactors
7.3 Importance of Correct Thickness
- Too thin → risk of failureand need to purchase again and will increase big cost
- Too thick → unnecessary cost,not an economic choice
8. Surface Finish
Common Types:
| Surface | Use Case |
| Bright Annealed (BA) | High-end industrial applications |
| Pickled | Standard industrial use |

13. FAQ
Q1: What is an ASTM B265 titanium plate?
A: This is a standard that covers the chemical composition, mechanical properties, dimensions, tolerances and surface requirements of titanium plates and sheets. The corresponding Chinese standard, GB/T 3621-2007, is largely identical in content and also specifies details regarding packaging and transportation.
ProX Metal has been deeply involved in the titanium industry for over 20 years. Meeting industry standards is our fundamental principle. Furthermore, our technical and production teams support custom requirements to meet a wide range of customer needs.
Q2: What is the difference between Gr1 and Gr2?
A: From a finished product perspective, Gr1 is softer and more suitable for forming, while Gr2 is harder and is used for industrial applications. GR1 is generally used for stamped parts and applications requiring high material ductility, while GR2 is better suited to applications subject to high stress.
If you are unsure which grade to choose, our professional technical team will consult with you to help resolve this issue. We can also provide free samples of GR1 and GR2 titanium sheets for testing purposes.
Q3: Can titanium sheets replace stainless steel?
A: Yes, especially in corrosive environments such as seawater or strong acids. However, for standard operating conditions, we recommend using stainless steel as this is more cost-effective for your project as a whole.
Q4: What is the recommended thickness for heat exchangers?
A: 0.5–2 mm, depending on the design. If you are concerned that this may not be suitable for your project, we can provide samples for testing. Common thicknesses for titanium plates are 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.2 mm and 1.5 mm.
Q5: Can titanium plates be welded?
A: Yes, but inert gas shielded welding must be used. It is important to note, however, that the welding material must match the grade of the plate being welded to ensure the best results.
Q6: How much does a kilogram of titanium plate cost?
A: The price varies depending on the grade, thickness and market conditions. Generally, thin sheets (less than 2 mm thick) are more expensive, ranging from 15–20 USD/kg, while thicker sheets are cheaper, at around 10–15 USD/kg. Please provide specific grades and thicknesses to receive an accurate quote!
Q7: Is GR2 suitable for pressure vessels?
A: Yes, GR2 is the most widely used grade in the industry thanks to its strength.
4. Conclusion
Titanium sheet (ASTM B265, Gr1 & Gr2) stands out as a reliable solution for industries where corrosion, weight, and long-term performance are critical. Compared with traditional materials, it offers a more stable and predictable service life, especially in demanding environments such as chemical processing, seawater systems, and heat exchangers.
By selecting the right grade, thickness, and surface finish—and aligning these choices with actual application conditions—engineers and procurement teams can not only improve equipment performance but also reduce long-term operational risks and maintenance costs.
In practice, the value of titanium sheet is not just in its properties, but in how effectively it is specified, processed, and applied.
