Steel 1030 vs C25E
Steel · grade comparison
Steel 1030 and C25E are both steel grades. C25E is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 260 MPa (37.7 ksi) for 1030, about 46% more; tensile strength follows at 610 MPa (88.5 ksi) vs 470 MPa (68.2 ksi). C25E is the more ductile: elongation 23% versus 20% for 1030, and C25E is harder (180 HB vs 137 HB). On the shop floor, C25E welds better (very good vs good).
C25EChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1030 vs C25E: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

1030 vs C25E — frequently asked
Is C25E stronger than 1030?
Yes. C25E has a typical yield strength of 380 MPa (55.1 ksi) against 260 MPa (37.7 ksi) for 1030 — about 46% more. Tensile strength is 610 MPa (88.5 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, 1030 or C25E?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1030 or C25E?
C25E, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 1030; for welding the order is C25E first (very good, 82/100) then 1030 (good, 62/100).
