Steel 33NiCrMoV14-5 +A vs 33NiCrMoV14-5 +N+T

Steel · 33NiCrMoV14-5 temper comparison

33NiCrMoV14-5 +A and 33NiCrMoV14-5 +N+T are two conditions of the same steel grade, 33NiCrMoV14-5: +A (annealed) versus +N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. 33NiCrMoV14-5 +N+T is the stronger of the two: yield strength 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for 33NiCrMoV14-5 +A, about 27% more; tensile strength follows at 950 MPa (138 ksi) vs 850 MPa (123 ksi). In exchange, 33NiCrMoV14-5 +A is the more ductile: elongation 18% versus 16% for 33NiCrMoV14-5 +N+T, and 33NiCrMoV14-5 +N+T is harder (285 HB vs 250 HB).

33NiCrMoV14-5 +AChoose it when the part is bent, formed or impact-loaded.

33NiCrMoV14-5 +N+TChoose it when strength drives the design.

33NiCrMoV14-5 +A vs 33NiCrMoV14-5 +N+T — frequently asked

Is 33NiCrMoV14-5 +N+T stronger than 33NiCrMoV14-5 +A?

Yes. 33NiCrMoV14-5 +N+T has a typical yield strength of 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for 33NiCrMoV14-5 +A — about 27% more. Tensile strength is 950 MPa (138 ksi) vs 850 MPa (123 ksi).

Which condition does FabDigit quote by default, +A or +N+T?

+QT is the default 33NiCrMoV14-5 condition in the FabDigit quote flow (neither +A nor +N+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.

Which is easier to machine, 33NiCrMoV14-5 +A or 33NiCrMoV14-5 +N+T?

33NiCrMoV14-5 +A, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 33NiCrMoV14-5 +N+T.
