Stainless Steel A286 Annealed vs A286 Solution Annealed
Stainless Steel · A286 temper comparison
A286 Annealed and A286 Solution Annealed are two conditions of the same stainless steel grade, A286: Annealed versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. A286 Solution Annealed is the stronger of the two: yield strength 310 MPa (45 ksi) against 260 MPa (37.7 ksi) for A286 Annealed, about 19% more; tensile strength follows at 690 MPa (100 ksi) vs 620 MPa (89.9 ksi). In exchange, A286 Annealed is the more ductile: elongation 45% versus 40% for A286 Solution Annealed, and A286 Solution Annealed is harder (170 HB vs 155 HB).
A286 AnnealedChoose it when the part is bent, formed or impact-loaded.
A286 Solution AnnealedChoose it when strength drives the design.
A286 Annealed vs A286 Solution Annealed: 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.
