Stainless Steel 1.4347 vs CE8MN
Stainless Steel · grade comparison
Stainless Steel 1.4347 and CE8MN are both stainless steel grades. Both yield at about 480 MPa — strength does not separate them. CE8MN is the more ductile: elongation 30% versus 26% for 1.4347, and 1.4347 is harder (225 HB vs 210 HB). 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 it will be welded.
1.4347 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.

1.4347 vs CE8MN — frequently asked
What is the difference between 1.4347 and CE8MN?
Stainless Steel 1.4347 and CE8MN are both stainless steel grades. Both yield at about 480 MPa — strength does not separate them. CE8MN is the more ductile: elongation 30% versus 26% for 1.4347, and 1.4347 is harder (225 HB vs 210 HB).
Which is cheaper, 1.4347 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, 1.4347 or CE8MN?
CE8MN. Its weldability rates good (65/100) against good (55/100) for 1.4347.
