Steel A514 vs EN19
Steel · grade comparison
Steel A514 and EN19 are both steel grades, both high strength steel. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 520 MPa (75.4 ksi) for EN19, about 46% more. A514 is harder — 250 HB against 235 HB for EN19 — which matters for wear surfaces and threads. EN19 conducts electricity better (7.8 % IACS vs 7 % IACS). On the shop floor, EN19 machines more easily (52 vs 38 out of 100) and A514 welds better (good vs fair).
A514Choose it when strength drives the design, or when surface hardness matters.
EN19Choose it when the part is machined in volume.
A514 vs EN19: 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.

A514 vs EN19 — frequently asked
Is A514 stronger than EN19?
Yes. A514 has a typical yield strength of 760 MPa (110 ksi) against 520 MPa (75.4 ksi) for EN19 — about 46% more. Tensile strength is 800 MPa (116 ksi) vs 800 MPa (116 ksi).
Which is cheaper, A514 or EN19?
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, A514 or EN19?
EN19, by a small margin. Both rate fair for machinability — 52/100 against 38/100 for A514; for welding the order is A514 first (good, 55/100) then EN19 (fair, 40/100).
