Steel A182 F23-ANN vs A182 F23 N+T

Steel · A182 F23 temper comparison

A182 F23-ANN and A182 F23 N+T are two conditions of the same steel grade, A182 F23: ANN (annealed) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F23 N+T is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 340 MPa (49.3 ksi) for A182 F23-ANN, about 41% more; tensile strength follows at 600 MPa (87 ksi) vs 520 MPa (75.4 ksi). In exchange, A182 F23-ANN is the more ductile: elongation 30% versus 25% for A182 F23 N+T, and A182 F23 N+T is harder (185 HB vs 150 HB). A182 F23 N+T runs hotter in service (600°C vs 500°C continuous).
