Stainless Steel 1.4517 vs CE8MN
Stainless Steel · grade comparison
Stainless Steel 1.4517 and CE8MN are both stainless steel grades. Both yield at about 520 MPa — strength does not separate them. CE8MN is the more ductile: elongation 30% versus 25% for 1.4517, and 1.4517 is harder (240 HB vs 210 HB). CE8MN runs hotter in service (315°C vs 260°C continuous). On the shop floor, CE8MN welds better (65 vs 55 out of 100).
CE8MNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4517 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.

1.4517 vs CE8MN — frequently asked
What is the difference between 1.4517 and CE8MN?
Stainless Steel 1.4517 and CE8MN are both stainless steel grades. Both yield at about 520 MPa — strength does not separate them. CE8MN is the more ductile: elongation 30% versus 25% for 1.4517, and 1.4517 is harder (240 HB vs 210 HB).
Which is cheaper, 1.4517 or CE8MN?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 1.4517 or CE8MN?
CE8MN. Its weldability rates good (65/100) against good (55/100) for 1.4517.
