Steel A516 Normalized vs A516 Q&T

Steel · A516 temper comparison

A516 Normalized and A516 Q&T are two conditions of the same steel grade, A516: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A516 Q&T is the stronger of the two: yield strength 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for A516 Normalized, about 21% more; tensile strength follows at 570 MPa (82.7 ksi) vs 525 MPa (76.1 ksi). In exchange, A516 Normalized is the more ductile: elongation 27% versus 24% for A516 Q&T, and A516 Q&T is harder (170 HB vs 150 HB).

A516 NormalizedChoose it when the part is bent, formed or impact-loaded.

A516 Q&TChoose it when strength drives the design.

A516 Normalized vs A516 Q&T — frequently asked

Is A516 Q&T stronger than A516 Normalized?

Yes. A516 Q&T has a typical yield strength of 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for A516 Normalized — about 21% more. Tensile strength is 570 MPa (82.7 ksi) vs 525 MPa (76.1 ksi).

Which condition does FabDigit quote by default, Normalized or Q&T?

HR is the default A516 condition in the FabDigit quote flow (neither Normalized nor Q&T). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose A516 Normalized over A516 Q&T?

Pick A516 Normalized when the part is bent, formed or impact-loaded. Pick A516 Q&T when strength drives the design.
