Steel P92 Normalized vs P92 Q&T
Steel · P92 temper comparison
P92 Normalized and P92 Q&T are two conditions of the same steel grade, P92: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. P92 Normalized is the stronger of the two: yield strength 900 MPa (131 ksi) against 580 MPa (84.1 ksi) for P92 Q&T, about 55% more; tensile strength follows at 1,250 MPa (181 ksi) vs 760 MPa (110 ksi). In exchange, P92 Q&T is the more ductile: elongation 20% versus 12% for P92 Normalized, and P92 Normalized is harder (400 HB vs 235 HB). P92 Q&T runs hotter in service (620°C vs 400°C continuous). On the shop floor, P92 Q&T machines more easily (fair vs poor).

P92 Normalized vs P92 Q&T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

P92 Normalized vs P92 Q&T — frequently asked
Is P92 Normalized stronger than P92 Q&T?
Yes. P92 Normalized has a typical yield strength of 900 MPa (131 ksi) against 580 MPa (84.1 ksi) for P92 Q&T — about 55% more. Tensile strength is 1,250 MPa (181 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, Normalized or Q&T?
HR is the default P92 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.
Which is easier to machine, P92 Normalized or P92 Q&T?
P92 Q&T. Its machinability rates fair (35/100) against poor (15/100) for P92 Normalized; for welding the order is P92 Q&T first (poor, 30/100) then P92 Normalized (poor, 25/100).
