Nickel Alloy Inconel 693 Aged vs Inconel 693-ANN

Nickel Alloy · Inconel 693 temper comparison

Inconel 693 Aged and Inconel 693-ANN are two conditions of the same nickel alloy grade, Inconel 693: Aged (annealed + Aged) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. Inconel 693 Aged is the stronger of the two: yield strength 600 MPa (87 ksi) against 400 MPa (58 ksi) for Inconel 693-ANN, about 50% more; tensile strength follows at 950 MPa (138 ksi) vs 790 MPa (115 ksi). In exchange, Inconel 693-ANN is the more ductile: elongation 45% versus 25% for Inconel 693 Aged, and Inconel 693 Aged is harder (290 HB vs 195 HB). On the shop floor, Inconel 693-ANN welds better (good vs fair).
