Stainless Steel 314 Annealed vs 314 Hot Rolled
Stainless Steel · 314 temper comparison
314 Annealed and 314 Hot Rolled are two conditions of the same stainless steel grade, 314: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Both yield at about 320 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 Hot Rolled). 314 Hot Rolled is harder — 190 HB against 170 HB for 314 Annealed — which matters for wear surfaces and threads.

314 Annealed vs 314 Hot Rolled: 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.

314 Annealed vs 314 Hot Rolled — frequently asked
What is the difference between 314 Annealed and 314 Hot Rolled?
314 Annealed and 314 Hot Rolled are two conditions of the same stainless steel grade, 314: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Both yield at about 320 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 Hot Rolled).
Which condition does FabDigit quote by default, Annealed or Hot Rolled?
Solution Annealed is the default 314 condition in the FabDigit quote flow (neither Annealed nor Hot Rolled). 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 314 Annealed over 314 Hot Rolled?
Pick 314 Hot Rolled when surface hardness matters.
