Stainless Steel 1.4474 vs CD3MCuN
Stainless Steel · grade comparison
Stainless Steel 1.4474 and CD3MCuN are both stainless steel grades. CD3MCuN is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 520 MPa (75.4 ksi) for 1.4474, about 6% more. CD3MCuN is the more ductile: elongation 32% versus 22% for 1.4474. On the shop floor, 1.4474 sits in a lower cost tier (premium, $$$) than CD3MCuN (high, $$$$).
1.4474Choose it when cost is the deciding factor.
CD3MCuNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4474 vs CD3MCuN: 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.
