Steel A514 vs EN41B
Steel · grade comparison
Steel A514 and EN41B are both steel grades. EN41B is the stronger of the two: tensile strength 925 MPa (134 ksi) against 800 MPa (116 ksi) for A514, about 16% more. In exchange, A514 is the more ductile: elongation 19% versus 15% for EN41B, and EN41B is harder (269 HB vs 250 HB). EN41B runs hotter in service (450°C vs 400°C continuous). On the shop floor, EN41B machines more easily (50 vs 38 out of 100) and A514 welds better (good vs poor).
A514Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
EN41BChoose it when strength drives the design, or when the part sees heat.
A514 vs EN41B: 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 EN41B — frequently asked
Is EN41B stronger than A514?
Yes. EN41B has a typical tensile strength of 925 MPa (134 ksi) against 800 MPa (116 ksi) for A514 — about 16% more.
Which is cheaper, A514 or EN41B?
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 EN41B?
EN41B, by a small margin. Both rate fair for machinability — 50/100 against 38/100 for A514; for welding the order is A514 first (good, 55/100) then EN41B (poor, 20/100).
