Stainless Steel S32803-CD vs S32803 CR-2B
Stainless Steel · S32803 temper comparison
S32803-CD and S32803 CR-2B are two conditions of the same stainless steel grade, S32803: CD (cold drawn) versus CR-2B (cold Rolled + Annealed). The chemistry is identical, so every difference below comes from the condition. S32803-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 510 MPa (74 ksi) for S32803 CR-2B, about 22% more; tensile strength follows at 740 MPa (107 ksi) vs 630 MPa (91.4 ksi). In exchange, S32803 CR-2B is the more ductile: elongation 26% versus 18% for S32803-CD, and S32803-CD is harder (225 HB vs 185 HB).

S32803-CD vs S32803 CR-2B: 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.

S32803-CD vs S32803 CR-2B — frequently asked
Is S32803-CD stronger than S32803 CR-2B?
Yes. S32803-CD has a typical yield strength of 620 MPa (89.9 ksi) against 510 MPa (74 ksi) for S32803 CR-2B — about 22% more. Tensile strength is 740 MPa (107 ksi) vs 630 MPa (91.4 ksi).
Which condition does FabDigit quote by default, CD or CR-2B?
ANN is the default S32803 condition in the FabDigit quote flow (neither CD nor CR-2B). 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, S32803-CD or S32803 CR-2B?
S32803 CR-2B. Its weldability rates fair (48/100) against fair (40/100) for S32803-CD.
