Stainless Steel 316N-ANN vs 316N-CD
Stainless Steel · 316N temper comparison
316N-ANN and 316N-CD are two conditions of the same stainless steel grade, 316N: ANN (annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 316N-CD is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 310 MPa (45 ksi) for 316N-ANN, about 68% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). In exchange, 316N-ANN is the more ductile: elongation 50% versus 25% for 316N-CD, and 316N-CD is harder (230 HB vs 165 HB). 316N-ANN runs hotter in service (800°C vs 300°C continuous).
316N-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
316N-CDChoose it when strength drives the design.
316N-ANN vs 316N-CD: 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.

316N-ANN vs 316N-CD — frequently asked
Is 316N-CD stronger than 316N-ANN?
Yes. 316N-CD has a typical yield strength of 520 MPa (75.4 ksi) against 310 MPa (45 ksi) for 316N-ANN — about 68% more. Tensile strength is 760 MPa (110 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, ANN or CD?
ANN is the default 316N condition in the FabDigit quote flow. 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 316N-ANN over 316N-CD?
Pick 316N-ANN when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 316N-CD when strength drives the design.
