Stainless Steel 1.4469 vs CD4MCuN
Stainless Steel · grade comparison
Stainless Steel 1.4469 and CD4MCuN are both stainless steel grades. Both yield at about 550 MPa — strength does not separate them. 1.4469 is the more ductile: elongation 28% versus 25% for CD4MCuN. CD4MCuN runs hotter in service (300°C vs 260°C continuous). On the shop floor, CD4MCuN sits in a lower cost tier (premium, $$$) than 1.4469 (high, $$$$).
1.4469Choose it when the part is bent, formed or impact-loaded.
CD4MCuNChoose it when the part sees heat, or when cost is the deciding factor.
1.4469 vs CD4MCuN: 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.
