Stainless Steel S32615-CD vs S32615-HF
Stainless Steel · S32615 temper comparison
S32615-CD and S32615-HF are two conditions of the same stainless steel grade, S32615: CD (cold drawn) versus HF (hot Finished). The chemistry is identical, so every difference below comes from the condition. S32615-CD is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 285 MPa (41.3 ksi) for S32615-HF, about 82% more; tensile strength follows at 750 MPa (109 ksi) vs 600 MPa (87 ksi). In exchange, S32615-HF is the more ductile: elongation 38% versus 22% for S32615-CD, and S32615-CD is harder (240 HB vs 175 HB). S32615-HF runs hotter in service (850°C vs 400°C continuous).
S32615-CDChoose it when strength drives the design.
S32615-HFChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S32615-CD vs S32615-HF: 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.

S32615-CD vs S32615-HF — frequently asked
Is S32615-CD stronger than S32615-HF?
Yes. S32615-CD has a typical yield strength of 520 MPa (75.4 ksi) against 285 MPa (41.3 ksi) for S32615-HF — about 82% more. Tensile strength is 750 MPa (109 ksi) vs 600 MPa (87 ksi).
Which condition does FabDigit quote by default, CD or HF?
Annealed is the default S32615 condition in the FabDigit quote flow (neither CD nor HF). 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, S32615-CD or S32615-HF?
S32615-CD. Its machinability rates fair (35/100) against poor (28/100) for S32615-HF; for welding the order is S32615-HF first (good, 55/100) then S32615-CD (fair, 50/100).
