Steel A514 Gr A vs A514-T6

Steel · A514 temper comparison

A514 Gr A and A514-T6 are two conditions of the same steel grade, A514: Gr A (grade A) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. A514-T6 is the stronger of the two: yield strength 780 MPa (113 ksi) against 730 MPa (106 ksi) for A514 Gr A, about 7% more.
