Titanium Grade 16 Annealed vs Grade 16 CW-SR

Titanium · Grade 16 temper comparison

Grade 16 Annealed and Grade 16 CW-SR are two conditions of the same titanium grade, Grade 16: Annealed versus CW-SR (cold worked + stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 16 CW-SR is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 380 MPa (55.1 ksi) for Grade 16 Annealed, about 37% more; tensile strength follows at 620 MPa (89.9 ksi) vs 485 MPa (70.3 ksi). In exchange, Grade 16 Annealed is the more ductile: elongation 28% versus 16% for Grade 16 CW-SR, and Grade 16 CW-SR is harder (200 HB vs 150 HB).
