Steel M10-ANN vs M10 ANN-CD
Steel · M10 temper comparison
M10-ANN and M10 ANN-CD are two conditions of the same steel grade, M10: ANN (annealed) versus ANN-CD (cold drawn annealed). The chemistry is identical, so every difference below comes from the condition. M10 ANN-CD is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 550 MPa (79.8 ksi) for M10-ANN, about 16% more; tensile strength follows at 880 MPa (128 ksi) vs 830 MPa (120 ksi). In exchange, M10-ANN is the more ductile: elongation 16% versus 12% for M10 ANN-CD, and M10 ANN-CD is harder (250 HB vs 235 HB).
M10-ANNChoose it when the part is bent, formed or impact-loaded.
M10 ANN-CDChoose it when strength drives the design.
M10-ANN vs M10 ANN-CD: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

M10-ANN vs M10 ANN-CD — frequently asked
Is M10 ANN-CD stronger than M10-ANN?
Yes. M10 ANN-CD has a typical yield strength of 640 MPa (92.8 ksi) against 550 MPa (79.8 ksi) for M10-ANN — about 16% more. Tensile strength is 880 MPa (128 ksi) vs 830 MPa (120 ksi).
Which condition does FabDigit quote by default, ANN or ANN-CD?
ANN is the default M10 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 M10-ANN over M10 ANN-CD?
Pick M10-ANN when the part is bent, formed or impact-loaded. Pick M10 ANN-CD when strength drives the design.
