Steel E335 +AR vs E335 +C
Steel · E335 temper comparison
E335 +AR and E335 +C are two conditions of the same steel grade, E335: +AR (hot rolled) versus +C (cold drawn). The chemistry is identical, so every difference below comes from the condition. E335 +C is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 355 MPa (51.5 ksi) for E335 +AR, about 58% more; tensile strength follows at 700 MPa (102 ksi) vs 620 MPa (89.9 ksi). In exchange, E335 +AR is the more ductile: elongation 18% versus 10% for E335 +C, and E335 +C is harder (210 HB vs 180 HB).

E335 +AR vs E335 +C: 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.

E335 +AR vs E335 +C — frequently asked
Is E335 +C stronger than E335 +AR?
Yes. E335 +C has a typical yield strength of 560 MPa (81.2 ksi) against 355 MPa (51.5 ksi) for E335 +AR — about 58% more. Tensile strength is 700 MPa (102 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, +AR or +C?
+AR is the default E335 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.
Which welds better, E335 +AR or E335 +C?
E335 +AR. Its weldability rates fair (45/100) against fair (40/100) for E335 +C.
