Steel 1006 vs C15E

Steel · grade comparison

Steel 1006 and C15E are both steel grades. C15E is the stronger of the two: yield strength 325 MPa (47.1 ksi) against 170 MPa (24.7 ksi) for 1006, about 91% more; tensile strength follows at 425 MPa (61.6 ksi) vs 300 MPa (43.5 ksi). C15E is the more ductile: elongation 35% versus 30% for 1006, and C15E is harder (121 HB vs 86 HB). 1006 conducts heat better (65 W/m·K vs 51 W/m·K).

C15EChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

1006 vs C15E — frequently asked

Is C15E stronger than 1006?

Yes. C15E has a typical yield strength of 325 MPa (47.1 ksi) against 170 MPa (24.7 ksi) for 1006 — about 91% more. Tensile strength is 425 MPa (61.6 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1006 or C15E?

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.

When should I choose 1006 over C15E?

Pick C15E when strength drives the design, or when the part is bent, formed or impact-loaded.
