Stainless Steel 1.4417 vs CE8MN
Stainless Steel · grade comparison
Stainless Steel 1.4417 and CE8MN are both stainless steel grades. 1.4417 is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 500 MPa (72.5 ksi) for CE8MN, about 12% more; tensile strength follows at 760 MPa (110 ksi) vs 720 MPa (104 ksi). 1.4417 is harder — 255 HB against 210 HB for CE8MN — which matters for wear surfaces and threads. On the shop floor, CE8MN machines more easily (32 vs 22 out of 100), CE8MN forms better (30 vs 20 out of 100), and CE8MN sits in a lower cost tier (premium, $$$) than 1.4417 (high, $$$$).
1.4417Choose it when strength drives the design, or when surface hardness matters.
CE8MNChoose it when the part is machined in volume, or when cost is the deciding factor.
1.4417 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.

1.4417 vs CE8MN — frequently asked
Is 1.4417 stronger than CE8MN?
Yes. 1.4417 has a typical yield strength of 560 MPa (81.2 ksi) against 500 MPa (72.5 ksi) for CE8MN — about 12% more. Tensile strength is 760 MPa (110 ksi) vs 720 MPa (104 ksi).
Which is cheaper, 1.4417 or CE8MN?
CE8MN is the lower-cost material: it sits in the premium tier ($$$) while 1.4417 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 1.4417 or CE8MN?
CE8MN, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for 1.4417; for welding the order is CE8MN first (good, 65/100) then 1.4417 (good, 60/100).
