Steel A216 WCC N+T vs A216 WCC Q+T

Steel · A216 WCC temper comparison

A216 WCC N+T and A216 WCC Q+T are two conditions of the same steel grade, A216 WCC: N+T (normalized and tempered) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A216 WCC Q+T is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 315 MPa (45.7 ksi) for A216 WCC N+T, about 21% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). A216 WCC Q+T is harder — 190 HB against 170 HB for A216 WCC N+T — which matters for wear surfaces and threads.

A216 WCC Q+TChoose it when strength drives the design, or when surface hardness matters.
