Steel A514 Grade B vs Hardox 600
Steel · grade comparison
Steel A514 Grade B and Hardox 600 are both steel grades. Hardox 600 is the stronger of the two: yield strength 1,650 MPa (239 ksi) against 760 MPa (110 ksi) for A514 Grade B, about 117% more; tensile strength follows at 2,000 MPa (290 ksi) vs 820 MPa (119 ksi). In exchange, A514 Grade B is the more ductile: elongation 19% versus 7% for Hardox 600, and Hardox 600 is harder (600 HB vs 255 HB). A514 Grade B runs hotter in service (400°C vs 250°C continuous) and A514 Grade B conducts heat better (42 W/m·K vs 30 W/m·K). On the shop floor, A514 Grade B machines more easily (fair vs not recommended), A514 Grade B welds better (good vs poor), and A514 Grade B sits in a lower cost tier (budget, $) than Hardox 600 (standard, $$).
A514 Grade BChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Hardox 600Choose it when strength drives the design.
A514 Grade B vs Hardox 600: 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.
