Stainless Steel N08700 Annealed vs N08700 Spring
Stainless Steel · N08700 temper comparison
N08700 Annealed and N08700 Spring are two conditions of the same stainless steel grade, N08700: Annealed versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. N08700 Spring is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 275 MPa (39.9 ksi) for N08700 Annealed, about 3.6 times as much; tensile strength follows at 1,200 MPa (174 ksi) vs 585 MPa (84.8 ksi). In exchange, N08700 Annealed is the more ductile: elongation 45% versus 5% for N08700 Spring, and N08700 Spring is harder (355 HB vs 160 HB). N08700 Annealed runs hotter in service (500°C vs 250°C continuous). On the shop floor, N08700 Annealed welds better (very good vs fair).
N08700 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N08700 SpringChoose it when strength drives the design.
N08700 Annealed vs N08700 Spring: 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.

N08700 Annealed vs N08700 Spring — frequently asked
Is N08700 Spring stronger than N08700 Annealed?
Yes. N08700 Spring has a typical yield strength of 1,000 MPa (145 ksi) against 275 MPa (39.9 ksi) for N08700 Annealed — about 3.6 times as much. Tensile strength is 1,200 MPa (174 ksi) vs 585 MPa (84.8 ksi).
Which condition does FabDigit quote by default, Annealed or Spring?
Annealed is the default N08700 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, N08700 Annealed or N08700 Spring?
N08700 Annealed, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for N08700 Spring; for welding the order is N08700 Annealed first (very good, 72/100) then N08700 Spring (fair, 45/100).
