Stainless Steel 1.4469 vs CE8MN
Stainless Steel · grade comparison
Stainless Steel 1.4469 and CE8MN are both stainless steel grades. 1.4469 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 500 MPa (72.5 ksi) for CE8MN, about 10% more; tensile strength follows at 760 MPa (110 ksi) vs 720 MPa (104 ksi). 1.4469 is harder — 250 HB against 210 HB for CE8MN — which matters for wear surfaces and threads. CE8MN runs hotter in service (315°C vs 260°C continuous). On the shop floor, CE8MN sits in a lower cost tier (premium, $$$) than 1.4469 (high, $$$$).
1.4469Choose it when strength drives the design, or when surface hardness matters.
CE8MNChoose it when the part sees heat, or when cost is the deciding factor.
1.4469 vs CE8MN: 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.
