Description
📘 Product Overview
GR12 Titanium Plate (Ti-0.3Mo-0.8Ni, UNS R53400) is a corrosion-resistant titanium alloy plate manufactured under ASTM B265 standards. Unlike commercially pure grades such as GR1 and GR2, Titanium Grade 12 Plate contains nickel and molybdenum, which enhance its performance in hot brines, seawater, and acidic environments.
This alloy is widely regarded as the “practical alternative” to palladium-bearing titanium grades like GR7, offering excellent corrosion resistance at a significantly lower cost. With its outstanding weldability and mechanical strength, ASTM B265 Grade 12 Titanium Sheet is a preferred choice in chemical plants, marine facilities, heat exchangers, and industrial piping systems.
🌟 Key Features & Advantages
✨ Superior Corrosion Resistance – Excellent protection against crevice corrosion in hot chloride and reducing environments.
💪 Enhanced Strength – Higher tensile and yield strength than GR2 titanium.
🛠️ Easy Fabrication – Readily welded with ERTi-12 filler wire and adaptable to machining.
💰 Cost Efficiency – Provides near GR7 performance at lower prices.
📜 Global Standard Compliance – Certified under ASTM B265 Grade 12 Titanium Sheet with EN 10204 3.1 certification.
⚗️ Chemical Composition
| Element | Content (%) | Function |
|---|---|---|
| Titanium | Balance | Structural base |
| Nickel | ~0.8 | Improves crevice corrosion resistance |
| Molybdenum | ~0.3 | Enhances resistance in reducing acids |
🧪 This alloying balance makes Ti-0.3Mo-0.8Ni Titanium Plate uniquely suited for severe industrial conditions.
📊 Mechanical Properties
