Steel 1030 vs C56E2
Steel · grade comparison
Steel 1030 and C56E2 are both steel grades. C56E2 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 260 MPa (37.7 ksi) for 1030, about 35% more; tensile strength follows at 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi). In exchange, 1030 is the more ductile: elongation 20% versus 18% for C56E2, and C56E2 is harder (180 HB vs 137 HB). 1030 runs hotter in service (400°C vs 300°C continuous). On the shop floor, 1030 machines more easily (good vs fair) and 1030 welds better (good vs poor).
1030Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C56E2Choose it when strength drives the design.
1030 vs C56E2: 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 C56E2 — frequently asked
Is C56E2 stronger than 1030?
Yes. C56E2 has a typical yield strength of 350 MPa (50.8 ksi) against 260 MPa (37.7 ksi) for 1030 — about 35% more. Tensile strength is 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, 1030 or C56E2?
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 C56E2?
1030. Its machinability rates good (55/100) against fair (45/100) for C56E2; for welding the order is 1030 first (good, 62/100) then C56E2 (poor, 25/100).
