Steel 35NiCrMo16 vs A514
Steel · grade comparison
Steel 35NiCrMo16 and A514 are both steel grades. 35NiCrMo16 is the stronger of the two: yield strength 1,150 MPa (167 ksi) against 760 MPa (110 ksi) for A514, about 51% more; tensile strength follows at 1,350 MPa (196 ksi) vs 800 MPa (116 ksi). In exchange, A514 is the more ductile: elongation 19% versus 11% for 35NiCrMo16, and 35NiCrMo16 is harder (400 HB vs 250 HB). 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, $$) than 35NiCrMo16 (premium, $$$).
35NiCrMo16Choose it when strength drives the design.
A514Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
35NiCrMo16 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.
