Titanium Grade 5 As Cast vs Grade 5 Stress Relieved

Titanium · Grade 5 temper comparison

Grade 5 As Cast and Grade 5 Stress Relieved are two conditions of the same titanium grade, Grade 5: As Cast versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Grade 5 Stress Relieved is the stronger of the two: yield strength 960 MPa (139 ksi) against 830 MPa (120 ksi) for Grade 5 As Cast, about 16% more; tensile strength follows at 1,050 MPa (152 ksi) vs 900 MPa (131 ksi). Grade 5 Stress Relieved is the more ductile: elongation 12% versus 8% for Grade 5 As Cast, and Grade 5 Stress Relieved is harder (334 HB vs 311 HB).

Grade 5 Stress RelievedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
