Stainless Steel N08535-CD vs N08535 CW-1/4H
Stainless Steel · N08535 temper comparison
N08535-CD and N08535 CW-1/4H are two conditions of the same stainless steel grade, N08535: CD (cold drawn) versus CW-1/4H (1/4 Hard). The chemistry is identical, so every difference below comes from the condition. N08535 CW-1/4H is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 520 MPa (75.4 ksi) for N08535-CD, about 12% more; tensile strength follows at 790 MPa (115 ksi) vs 720 MPa (104 ksi). In exchange, N08535-CD is the more ductile: elongation 25% versus 18% for N08535 CW-1/4H, and N08535 CW-1/4H is harder (250 HB vs 230 HB). N08535-CD runs hotter in service (400°C vs 300°C continuous).
N08535-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N08535 CW-1/4HChoose it when strength drives the design.
N08535-CD vs N08535 CW-1/4H: 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 CW-1/4H — frequently asked
Is N08535 CW-1/4H stronger than N08535-CD?
Yes. N08535 CW-1/4H has a typical yield strength of 580 MPa (84.1 ksi) against 520 MPa (75.4 ksi) for N08535-CD — about 12% more. Tensile strength is 790 MPa (115 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, CD or CW-1/4H?
ANN is the default N08535 condition in the FabDigit quote flow (neither CD nor CW-1/4H). 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 CW-1/4H?
Pick N08535-CD when the part is bent, formed or impact-loaded, or when the part sees heat. Pick N08535 CW-1/4H when strength drives the design.
