Stainless Steel 1.4837 vs CE30
Stainless Steel · grade comparison
Stainless Steel 1.4837 and CE30 are both stainless steel grades. CE30 is the stronger of the two: yield strength 434 MPa (62.9 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 64% more; tensile strength follows at 669 MPa (97 ksi) vs 520 MPa (75.4 ksi). CE30 is the more ductile: elongation 18% versus 12% for 1.4837. 1.4837 runs hotter in service (1,050°C vs 650°C continuous) and CE30 conducts heat better (16.2 W/m·K vs 14.5 W/m·K). On the shop floor, CE30 machines more easily (33 vs 22 out of 100) and CE30 welds better (50 vs 40 out of 100).
1.4837Choose it when the part sees heat.
CE30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs CE30: 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.

1.4837 vs CE30 — frequently asked
Is CE30 stronger than 1.4837?
Yes. CE30 has a typical yield strength of 434 MPa (62.9 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 64% more. Tensile strength is 669 MPa (97 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4837 or CE30?
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 is easier to machine, 1.4837 or CE30?
CE30, by a small margin. Both rate poor for machinability — 33/100 against 22/100 for 1.4837; for welding the order is CE30 first (fair, 50/100) then 1.4837 (fair, 40/100).
