Stainless Steel R20033 Annealed vs R20033-AW
Stainless Steel · R20033 temper comparison
R20033 Annealed and R20033-AW are two conditions of the same stainless steel grade, R20033: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. R20033 Annealed is the stronger of the two: tensile strength 800 MPa (116 ksi) against 760 MPa (110 ksi) for R20033-AW, about 5% more. R20033 Annealed is the more ductile: elongation 45% versus 30% for R20033-AW.
R20033 AnnealedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
R20033 Annealed vs R20033-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.
