Steel 1035 vs 56Mn4
Steel · grade comparison
Steel 1035 and 56Mn4 are both steel grades. 56Mn4 is the stronger of the two: yield strength 400 MPa (58 ksi) against 320 MPa (46.4 ksi) for 1035, about 25% more; tensile strength follows at 690 MPa (100 ksi) vs 585 MPa (84.8 ksi). In exchange, 1035 is the more ductile: elongation 18% versus 15% for 56Mn4, and 56Mn4 is harder (205 HB vs 163 HB). 1035 runs hotter in service (425°C vs 350°C continuous) and 1035 conducts electricity better (10.8 % IACS vs 8.5 % IACS). On the shop floor, 1035 machines more easily (good vs fair) and 1035 welds better (good vs poor).
1035Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
56Mn4Choose it when strength drives the design.
1035 vs 56Mn4: 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.

1035 vs 56Mn4 — frequently asked
Is 56Mn4 stronger than 1035?
Yes. 56Mn4 has a typical yield strength of 400 MPa (58 ksi) against 320 MPa (46.4 ksi) for 1035 — about 25% more. Tensile strength is 690 MPa (100 ksi) vs 585 MPa (84.8 ksi).
Which is cheaper, 1035 or 56Mn4?
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, 1035 or 56Mn4?
1035. Its machinability rates good (60/100) against fair (48/100) for 56Mn4; for welding the order is 1035 first (good, 55/100) then 56Mn4 (poor, 25/100).
