Steel E6010 vs J506
Steel · grade comparison
Steel E6010 and J506 are both steel grades. J506 is the stronger of the two: yield strength 440 MPa (63.8 ksi) against 400 MPa (58 ksi) for E6010, about 10% more; tensile strength follows at 540 MPa (78.3 ksi) vs 480 MPa (69.6 ksi). J506 is harder — 170 HB against 155 HB for E6010 — which matters for wear surfaces and threads. On the shop floor, J506 sits in a lower cost tier (budget, $) than E6010 (standard, $$).
J506Choose it when strength drives the design, or when surface hardness matters.
E6010 vs J506: 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.
