Titanium Sheet Applications in Chemical Industry – GR1 & GR2 Industrial Use Cases
Titanium Sheets, especiallyGR1 and GR2 in ASTM B265 standard, are widely used in the chemical industry due to their outstanding corrosion resistance, high strength, and durability.
From reaction vessels, piping systems, to storage tanks, titanium offers a long-term solution where stainless steel or carbon steel would corrode quickly. Understanding the right grade, thickness, and surface finish is key to maximizing both performance and lifespan.

Why Titanium Sheets Are Preferred in Chemical Industry?
Corrosion Resistance
- Resistant to chlorides, acids, and aggressive chemicals.
- Ideal for sulfuric acid, hydrochloric acid, and caustic soda applications.
- Strength-to-Weight Advantage: High strength at a low density reduces supporting structure costs.
- Long Service Life: Minimal maintenance, lower downtime, and long-term durability.
Compatibility with Fabrication: Can be welded, formed, or cut without losing mechanical or corrosion properties.
Common Applications
1. Chemical Storage Tanks
- Material:GR2, 6–12mm thickness
- Use Case:Storing concentrated acids or caustic solutions
- Surface Finish:Pickled for maximum corrosion resistance
- Notes:Proper edge trimming and leveling are critical to avoid stress points
2. Reaction Vessels
- Material:GR1 or GR2
- Use Case:Medium to high temperature chemical reactions
- Considerations:Choose thickness based on pressure and thermal expansion
- Fabrication Tip:Multi-pass TIG welding ensures strong, leak-proof joints
3. Piping & Heat Exchanger Components
- Material:GR2, 4–8mm
- Use Case:Transport of corrosive fluids
- Benefit:Low maintenance and minimal chemical interaction
- Processing Tip:Cut-to-Length ensures precise dimensions for assembly
4. Corrosive Process Equipment
- Includes agitators, pumps, and immersion heaters
- Material Selection:GR2 preferred for high corrosion environments
Welding & Surface Finish: Pickled sheets reduce chemical attack on welds
Selection Guidelines for Chemical Applications
| Component | Recommended Grade | Thickness | Surface Finish | Notes |
| Storage Tanks | GR2 | 6–12mm | Pickled | Edge trimming + leveling critical |
| Reaction Vessels | GR1/GR2 | 4–10mm | BA or Pickled | Depends on temperature and visibility |
| Piping | GR2 | 3–8mm | Pickled | CTL sheets for precise length |
| Pumps & Agitators | GR2 | 4–6mm | Pickled | Welding & fabrication precautions needed |
Industrial Case Study
Company: Large chemical plant in domestic
- Material:Gr2 Titanium sheets, 6mm thick, pickled
- Application:Storage tanks for sulfuric acid
- Challenge:Conventional steel tanks suffered corrosion within 12 months
- Solution:GR2 sheets cut-to-length, leveled, welded with TIG, pickled surface
- Result:Tanks in service >10 years with minimal maintenance, zero leaks
Using titanium sheets for chemical applications can dramatically improve durability and reduce maintenance costs. If you're planning a new chemical installation or upgrading existing equipment:
- Review your grade and surface finish requirements
