Titanium Grade 12 provides improved corrosion resistance and mechanical strength while maintaining many of the beneficial fabrication characteristics of commercially pure titanium.
Nickel and molybdenum additions improve resistance in reducing and aggressive chemical environments.
Offers improved resistance to crevice corrosion, particularly in chloride- containing environments.
Provides higher strength than many commercially pure titanium grades.
Can be fabricated and welded using appropriate procedures for titanium alloys.
Titanium Grade 12 is selected for applications requiring corrosion resistance, improved strength and reliable performance in demanding environments.
Process equipment used in reducing and aggressive chemical environments.
Shell and tube heat exchangers requiring corrosion-resistant materials.
Pressure vessel components requiring corrosion resistance and reliable strength.
Pipes, fittings and components used in demanding industrial environments.
Consider chemical concentration, temperature, chlorides and reducing conditions when selecting the material.
Appropriate fabrication and welding procedures are required to maintain material performance.
Grade 12 provides a useful combination of corrosion resistance and improved mechanical strength.
The commonly listed Werkstoff / EN cross-reference for Titanium Grade 12 is 3.7105. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
It is commonly used in chemical processing, heat exchangers, pressure vessels and corrosion-resistant industrial equipment.
Nickel and molybdenum improve corrosion resistance, particularly in reducing and chloride-containing environments.
