Steel E6010-AW vs E6010-SR
Steel · E6010 temper comparison
E6010-AW and E6010-SR are two conditions of the same steel grade, E6010: AW (as-welded deposit) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. E6010-AW is the stronger of the two: yield strength 400 MPa (58 ksi) against 370 MPa (53.7 ksi) for E6010-SR, about 8% more; tensile strength follows at 480 MPa (69.6 ksi) vs 455 MPa (66 ksi). E6010-AW is harder — 155 HB against 145 HB for E6010-SR — which matters for wear surfaces and threads.
E6010-AWChoose it when strength drives the design, or when surface hardness matters.
E6010-AW vs E6010-SR: 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.

E6010-AW vs E6010-SR — frequently asked
Is E6010-AW stronger than E6010-SR?
Yes. E6010-AW has a typical yield strength of 400 MPa (58 ksi) against 370 MPa (53.7 ksi) for E6010-SR — about 8% more. Tensile strength is 480 MPa (69.6 ksi) vs 455 MPa (66 ksi).
Which condition does FabDigit quote by default, AW or SR?
AW is the default E6010 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose E6010-AW over E6010-SR?
Pick E6010-AW when strength drives the design, or when surface hardness matters.
