Stainless Steel Alloy 611 Annealed vs Alloy 611-AW
Stainless Steel · Alloy 611 temper comparison
Alloy 611 Annealed and Alloy 611-AW are two conditions of the same stainless steel grade, Alloy 611: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Alloy 611-AW is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 330 MPa (47.9 ksi) for Alloy 611 Annealed, about 6% more. In exchange, Alloy 611 Annealed is the more ductile: elongation 45% versus 30% for Alloy 611-AW, and Alloy 611-AW is harder (200 HB vs 190 HB).
Alloy 611 AnnealedChoose it when the part is bent, formed or impact-loaded.
Alloy 611-AWChoose it when strength drives the design.
Alloy 611 Annealed vs Alloy 611-AW: 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.
