Steel A514 vs En47
Steel · grade comparison
Steel A514 and En47 are both steel grades. En47 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 760 MPa (110 ksi) for A514, about 91% more; tensile strength follows at 1,600 MPa (232 ksi) vs 800 MPa (116 ksi). In exchange, A514 is the more ductile: elongation 19% versus 8% for En47, and En47 is harder (425 HB vs 250 HB). A514 runs hotter in service (400°C vs 250°C continuous) and En47 conducts electricity better (7.8 % IACS vs 7 % IACS). On the shop floor, A514 machines more easily (fair vs poor), A514 welds better (good vs poor), and En47 sits in a lower cost tier (budget, $) than A514 (standard, $$).
A514Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
En47Choose it when strength drives the design, or when cost is the deciding factor.
A514 vs En47: 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.
