Steel Ferrium S53 AMS5922-SCT482 vs Ferrium S53-ANN
Steel · Ferrium S53 temper comparison
Ferrium S53 AMS5922-SCT482 and Ferrium S53-ANN are two conditions of the same steel grade, Ferrium S53: AMS5922-SCT482 (AMS 5922) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. Ferrium S53 AMS5922-SCT482 is the stronger of the two: yield strength 1,620 MPa (235 ksi) against 850 MPa (123 ksi) for Ferrium S53-ANN, about 91% more; tensile strength follows at 1,985 MPa (288 ksi) vs 1,100 MPa (160 ksi). In exchange, Ferrium S53-ANN is the more ductile: elongation 18% versus 12% for Ferrium S53 AMS5922-SCT482, and Ferrium S53 AMS5922-SCT482 is harder (54 HRC vs 34 HRC). On the shop floor, Ferrium S53-ANN machines more easily (32 vs 18 out of 100).

Ferrium S53 AMS5922-SCT482 vs Ferrium S53-ANN: 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.

Is Ferrium S53 AMS5922-SCT482 stronger than Ferrium S53-ANN?
Yes. Ferrium S53 AMS5922-SCT482 has a typical yield strength of 1,620 MPa (235 ksi) against 850 MPa (123 ksi) for Ferrium S53-ANN — about 91% more. Tensile strength is 1,985 MPa (288 ksi) vs 1,100 MPa (160 ksi).
Which condition does FabDigit quote by default, AMS5922-SCT482 or ANN?
AMS5922-SCT482 is the default Ferrium S53 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, Ferrium S53 AMS5922-SCT482 or Ferrium S53-ANN?
Ferrium S53-ANN, by a small margin. Both rate poor for machinability — 32/100 against 18/100 for Ferrium S53 AMS5922-SCT482; for welding the order is Ferrium S53-ANN first (poor, 30/100) then Ferrium S53 AMS5922-SCT482 (poor, 25/100).
