Steel 1330 Normalized vs 1330 Q&T

Steel · 1330 temper comparison

1330 Normalized and 1330 Q&T are two conditions of the same steel grade, 1330: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 1330 Q&T is the stronger of the two: yield strength 830 MPa (120 ksi) against 560 MPa (81.2 ksi) for 1330 Normalized, about 48% more; tensile strength follows at 910 MPa (132 ksi) vs 835 MPa (121 ksi). In exchange, 1330 Normalized is the more ductile: elongation 22% versus 18% for 1330 Q&T, and 1330 Q&T is harder (263 HB vs 248 HB).

1330 NormalizedChoose it when the part is bent, formed or impact-loaded.

1330 Q&TChoose it when strength drives the design.

1330 Normalized vs 1330 Q&T — frequently asked

Is 1330 Q&T stronger than 1330 Normalized?

Yes. 1330 Q&T has a typical yield strength of 830 MPa (120 ksi) against 560 MPa (81.2 ksi) for 1330 Normalized — about 48% more. Tensile strength is 910 MPa (132 ksi) vs 835 MPa (121 ksi).

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

HR is the default 1330 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 1330 Normalized over 1330 Q&T?

Pick 1330 Normalized when the part is bent, formed or impact-loaded. Pick 1330 Q&T when strength drives the design.
