Steel 5015 vs SCM415
Steel · grade comparison
Steel 5015 and SCM415 are both steel grades. SCM415 is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 285 MPa (41.3 ksi) for 5015, about 51% more; tensile strength follows at 640 MPa (92.8 ksi) vs 415 MPa (60.2 ksi). In exchange, 5015 is the more ductile: elongation 32% versus 22% for SCM415, and SCM415 is harder (180 HB vs 121 HB). 5015 conducts electricity better (9.5 % IACS vs 7.8 % IACS). On the shop floor, 5015 welds better (very good vs good) and 5015 sits in a lower cost tier (budget, $) than SCM415 (standard, $$).
5015Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
SCM415Choose it when strength drives the design.
5015 vs SCM415: 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.
