Steel 20CrMnTi vs A514
Steel · grade comparison
Steel 20CrMnTi and A514 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 400 MPa (58 ksi) for 20CrMnTi, about 90% more; tensile strength follows at 800 MPa (116 ksi) vs 620 MPa (89.9 ksi). In exchange, 20CrMnTi is the more ductile: elongation 22% versus 19% for A514, and A514 is harder (250 HB vs 187 HB). A514 runs hotter in service (400°C vs 350°C continuous). On the shop floor, 20CrMnTi machines more easily (good vs fair) and A514 welds better (good vs fair).
20CrMnTiChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
A514Choose it when strength drives the design, or when the part sees heat.
20CrMnTi vs A514: 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.

20CrMnTi vs A514 — frequently asked
Is A514 stronger than 20CrMnTi?
Yes. A514 has a typical yield strength of 760 MPa (110 ksi) against 400 MPa (58 ksi) for 20CrMnTi — about 90% more. Tensile strength is 800 MPa (116 ksi) vs 620 MPa (89.9 ksi).
Which is cheaper, 20CrMnTi or A514?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 20CrMnTi or A514?
20CrMnTi. Its machinability rates good (58/100) against fair (38/100) for A514; for welding the order is A514 first (good, 55/100) then 20CrMnTi (fair, 40/100).
