Steel A182 F5a vs A514
Steel · grade comparison
Steel A182 F5a and A514 are both steel grades. A514 is the stronger of the two: yield strength 760 MPa (110 ksi) against 480 MPa (69.6 ksi) for A182 F5a, about 58% more; tensile strength follows at 800 MPa (116 ksi) vs 690 MPa (100 ksi). In exchange, A182 F5a is the more ductile: elongation 24% versus 19% for A514, and A514 is harder (250 HB vs 215 HB). A182 F5a runs hotter in service (600°C vs 400°C continuous) and A514 conducts heat better (42 W/m·K vs 36 W/m·K). On the shop floor, A182 F5a machines more easily (48 vs 38 out of 100) and A514 welds better (good vs fair).
A182 F5aChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
A514Choose it when strength drives the design, or when it will be welded.
A182 F5a 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.

A182 F5a vs A514 — frequently asked
Is A514 stronger than A182 F5a?
Yes. A514 has a typical yield strength of 760 MPa (110 ksi) against 480 MPa (69.6 ksi) for A182 F5a — about 58% more. Tensile strength is 800 MPa (116 ksi) vs 690 MPa (100 ksi).
Which is cheaper, A182 F5a 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, A182 F5a or A514?
A182 F5a, by a small margin. Both rate fair for machinability — 48/100 against 38/100 for A514; for welding the order is A514 first (good, 55/100) then A182 F5a (fair, 40/100).
