Steel 1.2344 Nitrided vs 1.2344 Q&T 52-54 HRC
Steel · 1.2344 temper comparison
1.2344 Nitrided and 1.2344 Q&T 52-54 HRC are two conditions of the same steel grade, 1.2344: Nitrided versus Q&T 52-54 HRC (low-temper, maximum-hardness condition). The chemistry is identical, so every difference below comes from the condition. 1.2344 Q&T 52-54 HRC is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 1,450 MPa (210 ksi) for 1.2344 Nitrided, about 14% more; tensile strength follows at 2,000 MPa (290 ksi) vs 1,700 MPa (247 ksi). In exchange, 1.2344 Nitrided is the more ductile: elongation 9% versus 5% for 1.2344 Q&T 52-54 HRC, and 1.2344 Nitrided is harder (455 HB vs 215 HB). 1.2344 Nitrided runs hotter in service (540°C vs 480°C continuous). On the shop floor, 1.2344 Q&T 52-54 HRC welds better (fair vs not recommended).

1.2344 Nitrided vs 1.2344 Q&T 52-54 HRC: 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.

1.2344 Nitrided vs 1.2344 Q&T 52-54 HRC — frequently asked
Is 1.2344 Q&T 52-54 HRC stronger than 1.2344 Nitrided?
Yes. 1.2344 Q&T 52-54 HRC has a typical yield strength of 1,650 MPa (239 ksi) against 1,450 MPa (210 ksi) for 1.2344 Nitrided — about 14% more. Tensile strength is 2,000 MPa (290 ksi) vs 1,700 MPa (247 ksi).
Which condition does FabDigit quote by default, Nitrided or Q&T 52-54 HRC?
Annealed is the default 1.2344 condition in the FabDigit quote flow (neither Nitrided nor Q&T 52-54 HRC). 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, 1.2344 Nitrided or 1.2344 Q&T 52-54 HRC?
1.2344 Q&T 52-54 HRC, by a small margin. Both rate not recommended for machinability — 10/100 against 5/100 for 1.2344 Nitrided; for welding the order is 1.2344 Q&T 52-54 HRC first (fair, 35/100) then 1.2344 Nitrided (not recommended, 5/100).
