Steel E6013 vs ER70S-2
Steel · grade comparison
Steel E6013 and ER70S-2 are both steel grades. ER70S-2 is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 400 MPa (58 ksi) for E6013, about 13% more; tensile strength follows at 560 MPa (81.2 ksi) vs 490 MPa (71.1 ksi). ER70S-2 is the more ductile: elongation 28% versus 25% for E6013. ER70S-2 runs hotter in service (400°C vs 350°C continuous). On the shop floor, E6013 sits in a lower cost tier (budget, $) than ER70S-2 (standard, $$).
E6013Choose it when cost is the deciding factor.
ER70S-2Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
E6013 vs ER70S-2: 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.
