Refractory Metal Ta-10W-ANN vs Ta-10W-SR

Refractory Metal · Ta-10W temper comparison

Ta-10W-ANN and Ta-10W-SR are two conditions of the same refractory metal grade, Ta-10W: ANN (annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Ta-10W-SR is the stronger of the two: yield strength 720 MPa (104 ksi) against 550 MPa (79.8 ksi) for Ta-10W-ANN, about 31% more; tensile strength follows at 830 MPa (120 ksi) vs 690 MPa (100 ksi). In exchange, Ta-10W-ANN is the more ductile: elongation 25% versus 15% for Ta-10W-SR, and Ta-10W-SR is harder (270 HB vs 225 HB).
