Steel A514 vs En30B
Steel · grade comparison
Steel A514 and En30B are both steel grades. En30B is the stronger of the two: yield strength 980 MPa (142 ksi) against 760 MPa (110 ksi) for A514, about 29% more; tensile strength follows at 1,150 MPa (167 ksi) vs 800 MPa (116 ksi). In exchange, A514 is the more ductile: elongation 19% versus 13% for En30B, and En30B is harder (340 HB vs 250 HB). A514 runs hotter in service (400°C vs 350°C continuous) and A514 conducts heat better (42 W/m·K vs 34 W/m·K). On the shop floor, A514 machines more easily (fair vs poor), A514 welds better (good vs poor), and A514 sits in a lower cost tier (standard, $$) than En30B (premium, $$$).
A514Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
En30BChoose it when strength drives the design.
A514 vs En30B: 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.
