Steel 2316 Annealed vs 2316 Nitrided
Steel · 2316 temper comparison
2316 Annealed and 2316 Nitrided are two conditions of the same steel grade, 2316: Annealed versus Nitrided. The chemistry is identical, so every difference below comes from the condition. 2316 Nitrided is the stronger of the two: yield strength 850 MPa (123 ksi) against 520 MPa (75.4 ksi) for 2316 Annealed, about 63% more; tensile strength follows at 1,020 MPa (148 ksi) vs 780 MPa (113 ksi). In exchange, 2316 Annealed is the more ductile: elongation 18% versus 10% for 2316 Nitrided, and 2316 Nitrided is harder (300 HB vs 235 HB). 2316 Nitrided runs hotter in service (450°C vs 400°C continuous). On the shop floor, 2316 Annealed machines more easily (fair vs not recommended) and 2316 Annealed welds better (poor vs not recommended).
2316 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
2316 NitridedChoose it when strength drives the design, or when the part sees heat.
2316 Annealed vs 2316 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.

2316 Annealed vs 2316 Nitrided — frequently asked
Is 2316 Nitrided stronger than 2316 Annealed?
Yes. 2316 Nitrided has a typical yield strength of 850 MPa (123 ksi) against 520 MPa (75.4 ksi) for 2316 Annealed — about 63% more. Tensile strength is 1,020 MPa (148 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, Annealed or Nitrided?
Annealed is the default 2316 condition in the FabDigit quote flow. 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, 2316 Annealed or 2316 Nitrided?
2316 Annealed. Its machinability rates fair (50/100) against not recommended (10/100) for 2316 Nitrided; for welding the order is 2316 Annealed first (poor, 30/100) then 2316 Nitrided (not recommended, 5/100).
