Steel A182 F24 N+T vs A182 F24 Q+T

Steel · A182 F24 temper comparison

A182 F24 N+T and A182 F24 Q+T are two conditions of the same steel grade, A182 F24: N+T (normalized and tempered) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F24 Q+T is the stronger of the two: yield strength 530 MPa (76.9 ksi) against 470 MPa (68.2 ksi) for A182 F24 N+T, about 13% more; tensile strength follows at 670 MPa (97.2 ksi) vs 620 MPa (89.9 ksi). A182 F24 Q+T is harder — 220 HB against 200 HB for A182 F24 N+T — which matters for wear surfaces and threads.

A182 F24 Q+TChoose it when strength drives the design, or when surface hardness matters.
