Nickel Alloy M35-2-ANN vs M35-2-SR
Nickel Alloy · M35-2 temper comparison
M35-2-ANN and M35-2-SR are two conditions of the same nickel alloy grade, M35-2: ANN (annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Both yield at about 210 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed versus stress relieved). M35-2-SR is harder — 125 HB against 118 HB for M35-2-ANN — which matters for wear surfaces and threads.

M35-2-ANN vs M35-2-SR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.

M35-2-ANN vs M35-2-SR — frequently asked
What is the difference between M35-2-ANN and M35-2-SR?
M35-2-ANN and M35-2-SR are two conditions of the same nickel alloy grade, M35-2: ANN (annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Both yield at about 210 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed versus stress relieved).
Which condition does FabDigit quote by default, ANN or SR?
AC is the default M35-2 condition in the FabDigit quote flow (neither ANN nor SR). 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 M35-2-ANN over M35-2-SR?
Pick M35-2-SR when surface hardness matters.
