This meta stable-beta alloy is strip-producible and cold-formable. The alloy has been used for springs, fasteners, torsion bars, sheet and foil applications. The alloy is age-hardenable to a wide range of strengths. Ti38644 is also being evaluated as extruded tubular for deep sour well applications.
Grade 20 is identical to grade 19 with the exception of the addition of palladium to increase its corrosion resistance. Mechanical and physical properties, specifications and forms, are identical to those of grade 19.
