Steel 1110 vs 1215
Steel · grade comparison
Steel 1110 and 1215 are both steel grades. 1110 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 250 MPa (36.3 ksi) for 1215, about 52% more; tensile strength follows at 440 MPa (63.8 ksi) vs 415 MPa (60.2 ksi). In exchange, 1215 is the more ductile: elongation 25% versus 15% for 1110. On the shop floor, 1110 welds better (fair vs poor).
1110Choose it when strength drives the design, or when it will be welded.
1215Choose it when the part is bent, formed or impact-loaded.
1110 vs 1215: 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.

1110 vs 1215 — frequently asked
Is 1110 stronger than 1215?
Yes. 1110 has a typical yield strength of 380 MPa (55.1 ksi) against 250 MPa (36.3 ksi) for 1215 — about 52% more. Tensile strength is 440 MPa (63.8 ksi) vs 415 MPa (60.2 ksi).
Which is cheaper, 1110 or 1215?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1110 or 1215?
1215. Its machinability rates excellent (85/100) against very good (78/100) for 1110; for welding the order is 1110 first (fair, 45/100) then 1215 (poor, 20/100).
