Steel 1.2344 Annealed vs 1.2344 Nitrided
Steel · 1.2344 temper comparison
1.2344 Annealed and 1.2344 Nitrided are two conditions of the same steel grade, 1.2344: Annealed versus Nitrided. The chemistry is identical, so every difference below comes from the condition. 1.2344 Nitrided is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 500 MPa (72.5 ksi) for 1.2344 Annealed, about 190% more; tensile strength follows at 1,700 MPa (247 ksi) vs 800 MPa (116 ksi). In exchange, 1.2344 Annealed is the more ductile: elongation 20% versus 9% for 1.2344 Nitrided, and 1.2344 Nitrided is harder (455 HB vs 215 HB). 1.2344 Nitrided runs hotter in service (540°C vs 400°C continuous). On the shop floor, 1.2344 Annealed machines more easily (fair vs not recommended) and 1.2344 Annealed welds better (fair vs not recommended).
1.2344 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.2344 NitridedChoose it when strength drives the design, or when the part sees heat.
1.2344 Annealed vs 1.2344 Nitrided: 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.
