Stainless Steel 316H Annealed vs 316H-CD
Stainless Steel · 316H temper comparison
316H Annealed and 316H-CD are two conditions of the same stainless steel grade, 316H: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 316H-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 245 MPa (35.5 ksi) for 316H Annealed, about 104% more; tensile strength follows at 700 MPa (102 ksi) vs 560 MPa (81.2 ksi). In exchange, 316H Annealed is the more ductile: elongation 50% versus 28% for 316H-CD, and 316H-CD is harder (220 HB vs 150 HB).
316H AnnealedChoose it when the part is bent, formed or impact-loaded.
316H-CDChoose it when strength drives the design.
316H Annealed vs 316H-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.

316H Annealed vs 316H-CD — frequently asked
Is 316H-CD stronger than 316H Annealed?
Yes. 316H-CD has a typical yield strength of 500 MPa (72.5 ksi) against 245 MPa (35.5 ksi) for 316H Annealed — about 104% more. Tensile strength is 700 MPa (102 ksi) vs 560 MPa (81.2 ksi).
Which condition does FabDigit quote by default, Annealed or CD?
Annealed is the default 316H 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.
Which is easier to machine, 316H Annealed or 316H-CD?
316H-CD, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for 316H Annealed.
