Titanium Grade 3 Sheet
What is Titanium Grade 3 Sheet?
Grade 3 titanium sheet is a commercially pure form of titanium. It is widely used for its combination of excellent formability, medium strength (slightly higher than Grade 2), and superior corrosion resistance. grade 3 industrial titanium sheet (ASTM B265, AMS 4900) combines these characteristics, making it ideal for a variety of chemical, marine, aerospace, and medical applications where strength is a concern.

Titanium Grade 3 is a commercially pure form of titanium. It is widely used because it combines excellent formability and moderate strength (slightly higher than that of Grade 2) with superior corrosion resistance. This combination of properties makes Grade 3 titanium (ASTM B265, AMS 4900) ideal for a large variety of chemical and marine as well as aerospace and medical applications where strength is a consideration.

Product Packaging
Our titanium products are packaged according to grade and application: CP grades (Gr1-4) are wrapped in protective plastic with moisture-proof barrier and wooden crates; alloy grades (Gr5, Gr23, Gr9, Gr12) include VCI paper and foam layer separation; medical-grade (Gr23 ELI) uses clean-room compatible double-layer sealing; welding wire is vacuum-sealed with desiccant. All packages feature edge protectors, steel banding, IPPC-certified wooden crates, and full labeling (grade, size, heat number) for safe sea freight delivery.
FAQ
What is the minimum order quantity?
Standard sizes: 1 sheet or 50 kg minimum
Sample orders: Negotiable for R&D/prototyping
Production orders: Negotiable based on thickness and quantity
Do you provide cut-to-size services?
Yes, we offer precision cutting services:
Shearing – for straight cuts
Water jet cutting – for precision shapes, no HAZ
Plasma cutting – for thicker sheets
Laser cutting – for precision shapes in thinner gauges
What is the minimum bend radius for Grade 3 sheet?
The minimum bend radius depends on thickness and direction:
Longitudinal: 2.0 × thickness
Transverse: 2.5 × thickness
For thickness > 3mm or complex bends, consider hot forming or larger radii.
