Stainless Steel N08535-CD vs N08535 HF-ANN
Stainless Steel · N08535 temper comparison
N08535-CD and N08535 HF-ANN are two conditions of the same stainless steel grade, N08535: CD (cold drawn) versus HF-ANN (hot Finished + Annealed). The chemistry is identical, so every difference below comes from the condition. N08535-CD is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for N08535 HF-ANN, about 104% more; tensile strength follows at 720 MPa (104 ksi) vs 575 MPa (83.4 ksi). In exchange, N08535 HF-ANN is the more ductile: elongation 42% versus 25% for N08535-CD, and N08535-CD is harder (230 HB vs 155 HB). N08535 HF-ANN runs hotter in service (550°C vs 400°C continuous).
N08535-CDChoose it when strength drives the design.
N08535 HF-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N08535-CD vs N08535 HF-ANN: 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.

N08535-CD vs N08535 HF-ANN — frequently asked
Is N08535-CD stronger than N08535 HF-ANN?
Yes. N08535-CD has a typical yield strength of 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for N08535 HF-ANN — about 104% more. Tensile strength is 720 MPa (104 ksi) vs 575 MPa (83.4 ksi).
Which condition does FabDigit quote by default, CD or HF-ANN?
ANN is the default N08535 condition in the FabDigit quote flow (neither CD nor HF-ANN). 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.
When should I choose N08535-CD over N08535 HF-ANN?
Pick N08535-CD when strength drives the design. Pick N08535 HF-ANN when the part is bent, formed or impact-loaded, or when the part sees heat.
