Steel A182 F92 N+T+PWHT vs A182 F92 Q+T

Steel · A182 F92 temper comparison

A182 F92 N+T+PWHT and A182 F92 Q+T are two conditions of the same steel grade, A182 F92: N+T+PWHT (N+T + simulated post-weld heat treatment) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F92 Q+T is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 480 MPa (69.6 ksi) for A182 F92 N+T+PWHT, about 17% more; tensile strength follows at 745 MPa (108 ksi) vs 670 MPa (97.2 ksi). In exchange, A182 F92 N+T+PWHT is the more ductile: elongation 24% versus 21% for A182 F92 Q+T, and A182 F92 Q+T is harder (235 HB vs 205 HB).
