Stainless Steel 253 MA Annealed vs 253 MA-AW
Stainless Steel · 253 MA temper comparison
253 MA Annealed and 253 MA-AW are two conditions of the same stainless steel grade, 253 MA: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 253 MA-AW is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 350 MPa (50.8 ksi) for 253 MA Annealed, about 20% more. In exchange, 253 MA Annealed is the more ductile: elongation 45% versus 32% for 253 MA-AW, and 253 MA-AW is harder (195 HB vs 180 HB).
253 MA AnnealedChoose it when the part is bent, formed or impact-loaded.
253 MA-AWChoose it when strength drives the design.
253 MA Annealed vs 253 MA-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.
