Stainless Steel S31254-CD vs S31254 Forged+SA
Stainless Steel · S31254 temper comparison
S31254-CD and S31254 Forged+SA are two conditions of the same stainless steel grade, S31254: CD (cold drawn) versus Forged+SA (forged + solution annealed). The chemistry is identical, so every difference below comes from the condition. S31254-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 330 MPa (47.9 ksi) for S31254 Forged+SA, about 67% more; tensile strength follows at 800 MPa (116 ksi) vs 670 MPa (97.2 ksi). In exchange, S31254 Forged+SA is the more ductile: elongation 45% versus 25% for S31254-CD, and S31254-CD is harder (255 HB vs 200 HB).

S31254-CD vs S31254 Forged+SA: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

S31254-CD vs S31254 Forged+SA — frequently asked
Is S31254-CD stronger than S31254 Forged+SA?
Yes. S31254-CD has a typical yield strength of 550 MPa (79.8 ksi) against 330 MPa (47.9 ksi) for S31254 Forged+SA — about 67% more. Tensile strength is 800 MPa (116 ksi) vs 670 MPa (97.2 ksi).
Which condition does FabDigit quote by default, CD or Forged+SA?
Annealed is the default S31254 condition in the FabDigit quote flow (neither CD nor Forged+SA). 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 welds better, S31254-CD or S31254 Forged+SA?
S31254 Forged+SA. Its weldability rates very good (70/100) against good (65/100) for S31254-CD.
