Stainless Steel 353 MA-CD vs 353 MA-SA
Stainless Steel · 353 MA temper comparison
353 MA-CD and 353 MA-SA are two conditions of the same stainless steel grade, 353 MA: CD (cold drawn) versus SA (solution annealed). The chemistry is identical, so every difference below comes from the condition. 353 MA-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 350 MPa (50.8 ksi) for 353 MA-SA, about 77% more; tensile strength follows at 880 MPa (128 ksi) vs 730 MPa (106 ksi). In exchange, 353 MA-SA is the more ductile: elongation 45% versus 22% for 353 MA-CD, and 353 MA-CD is harder (250 HB vs 180 HB).
353 MA-CDChoose it when strength drives the design.
353 MA-SAChoose it when the part is bent, formed or impact-loaded.
353 MA-CD vs 353 MA-SA: 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.
