Steel T13A-N vs T13A QT60-62

Steel · T13A temper comparison

T13A-N and T13A QT60-62 are two conditions of the same steel grade, T13A: N (normalized) versus QT60-62 (Q&T 60–62 HRC). The chemistry is identical, so every difference below comes from the condition. T13A QT60-62 is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 520 MPa (75.4 ksi) for T13A-N, about 3.3 times as much; tensile strength follows at 1,950 MPa (283 ksi) vs 950 MPa (138 ksi). In exchange, T13A-N is the more ductile: elongation 8% versus 1% for T13A QT60-62, and T13A-N is harder (290 HB vs 197 HB). T13A-N runs hotter in service (250°C vs 180°C continuous) and T13A-N conducts heat better (45 W/m·K vs 40 W/m·K). On the shop floor, T13A-N machines more easily (poor vs not recommended).

T13A-NChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

T13A QT60-62Choose it when strength drives the design.

T13A-N vs T13A QT60-62 — frequently asked

Is T13A QT60-62 stronger than T13A-N?

Yes. T13A QT60-62 has a typical yield strength of 1,700 MPa (247 ksi) against 520 MPa (75.4 ksi) for T13A-N — about 3.3 times as much. Tensile strength is 1,950 MPa (283 ksi) vs 950 MPa (138 ksi).

Which condition does FabDigit quote by default, N or QT60-62?

A is the default T13A condition in the FabDigit quote flow (neither N nor QT60-62). 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.

Which is easier to machine, T13A-N or T13A QT60-62?

T13A-N. Its machinability rates poor (30/100) against not recommended (8/100) for T13A QT60-62; for welding the order is T13A-N first (not recommended, 10/100) then T13A QT60-62 (not recommended, 3/100).
