Steel 1113 vs 1215

Steel · grade comparison

Steel 1113 and 1215 are both steel grades. 1113 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 250 MPa (36.3 ksi) for 1215, about 66% more; tensile strength follows at 495 MPa (71.8 ksi) vs 415 MPa (60.2 ksi). In exchange, 1215 is the more ductile: elongation 25% versus 10% for 1113, and 1113 is harder (170 HB vs 121 HB). 1215 runs hotter in service (400°C vs 350°C continuous).

1113Choose it when strength drives the design.

1215Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1113 vs 1215 — frequently asked

Is 1113 stronger than 1215?

Yes. 1113 has a typical yield strength of 415 MPa (60.2 ksi) against 250 MPa (36.3 ksi) for 1215 — about 66% more. Tensile strength is 495 MPa (71.8 ksi) vs 415 MPa (60.2 ksi).

Which is cheaper, 1113 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, 1113 or 1215?

1113, by a small margin. Both rate excellent for machinability — 92/100 against 85/100 for 1215; for welding the order is 1215 first (poor, 20/100) then 1113 (poor, 15/100).
