Titanium Grade 12
Titanium Grade 12 is a highly durable "near-alpha" alloy that offers a significant step up in performance from commercially pure grades. By incorporating small amounts of Molybdenum and Nickel, this grade bridges the gap between the pure titanium series and the more expensive palladium-bearing alloys. It is specifically engineered to provide enhanced strength and superior crevice corrosion resistance, particularly in high-temperature brine and mildly reducing environments.
Why Grade 12 Stands Out
- Enhanced Heat Resistance: Unlike standard CP grades, Grade 11 maintains its structural integrity and corrosion defense at much higher temperatures.
- Economical Corrosion Protection: Provides a cost-effective alternative to Grade 7 or Grade 11 when extreme acid resistance is needed but budget is a factor.
- Superior Crevice Defense: The addition of Nickel and Molybdenum acts as a deterrent against localized pitting in tight gaps and under-deposit areas.
- High-Strength Profile: Offers better mechanical properties than Grade 2 while remaining highly weldable and formable.
- Oxidizing & Reducing Versatility: Performs exceptionally well in environments that fluctuate between oxidizing and mildly reducing conditions.
Technical Specification & Performance
Alloy Chemistry:
Grade 12 is defined by its precise balance of 0.3% Molybdenum and 0.8% Nickel. These elements refine the grain structure and bolster the protective oxide film, making the metal much tougher against chemical attack than unalloyed versions.
Mechanical Characteristics:
- Higher yield strength than Grade 2 Titanium.
- Excellent resistance to stress-corrosion cracking.
- Retains high ductility for bending and cold-forming processes.
- Superior erosion resistance in high-velocity fluid environments.
Primary Industrial Use Cases
Aries Alloys is a premier source for Grade 12 components across several heavy-duty industries:
- Shell & Tube Heat Exchangers: Often the first choice for equipment handling hot, high-chloride fluids.
- Hydrometallurgical Processing: Used in autoclaves and piping for ore extraction where heat and acids are combined.
- Marine Components: Ideal for splash-zone hardware and subsea equipment requiring more strength than pure titanium.
- Geothermal Energy: Vital for piping systems and valves exposed to high-pressure steam and aggressive minerals.
- Desalination: Used in high-temperature brine heaters and evaporation stages.
