Stainless Steel 316L Annealed vs 316L As Sintered
Stainless Steel · 316L temper comparison
316L Annealed and 316L As Sintered are two conditions of the same stainless steel grade, 316L: Annealed versus As Sintered (sintered). The chemistry is identical, so every difference below comes from the condition. 316L Annealed is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 200 MPa (29 ksi) for 316L As Sintered, about 40% more; tensile strength follows at 565 MPa (81.9 ksi) vs 520 MPa (75.4 ksi). 316L Annealed is the more ductile: elongation 50% versus 45% for 316L As Sintered, and 316L Annealed is harder (150 HB vs 125 HB). 316L Annealed is stiffer (193 GPa vs 175 GPa).

316L Annealed vs 316L As Sintered: 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.

316L Annealed vs 316L As Sintered — frequently asked
Is 316L Annealed stronger than 316L As Sintered?
Yes. 316L Annealed has a typical yield strength of 280 MPa (40.6 ksi) against 200 MPa (29 ksi) for 316L As Sintered — about 40% more. Tensile strength is 565 MPa (81.9 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, Annealed or As Sintered?
Solution Annealed is the default 316L condition in the FabDigit quote flow (neither Annealed nor As Sintered). 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 welds better, 316L Annealed or 316L As Sintered?
316L Annealed. Its weldability rates excellent (90/100) against excellent (85/100) for 316L As Sintered.
