Titanium Grade 7 provides the beneficial characteristics of commercially pure titanium together with enhanced corrosion resistance from its palladium addition.
Palladium improves resistance in reducing and aggressive environments.
Offers improved resistance to crevice corrosion in chloride-containing environments.
Retains useful fabrication and forming characteristics of commercially pure titanium.
Can be fabricated using appropriate welding procedures for titanium.
Titanium Grade 7 is selected for applications requiring superior corrosion resistance in aggressive chemical environments.
Process equipment exposed to aggressive and corrosive chemical environments.
Components used in chloride-containing environments requiring improved resistance.
Corrosion-resistant components used in demanding process equipment.
Fabricated equipment used in aggressive industrial service 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 7 is generally selected where enhanced corrosion resistance is more important than maximum mechanical strength.
The commonly listed Werkstoff / EN cross-reference for Titanium Grade 7 is 3.7235. 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 and aggressive industrial environments, particularly chloride-containing media.
Palladium improves corrosion resistance, particularly in reducing environments and applications involving chloride-containing media.
