Titanium Grade 7: Corrosion-Led Grade Selection

Grade 7 is a palladium-bearing titanium grade. Material reference.

Corrosion-Led Grade Selection

For a chemical-service part, make the actual environment the basis of selection. Do not assume that a change from Grade 2 to Grade 7 resolves every corrosion mechanism or eliminates the need to review crevices, temperature and contaminants.

Manufacturing and acceptance checks

Supply the process-fluid composition, temperature range, product form and applicable specification. Request evidence relevant to the operating environment and the final joined condition. Define cleanliness, sealing-surface finish and traceability, and document the acceptance criteria before approving a material change. Include contaminants and cleaning fluids in that review.
