Steel 1006 vs C17C

Steel · grade comparison

Steel 1006 and C17C are both steel grades. C17C is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 170 MPa (24.7 ksi) for 1006, about 165% more; tensile strength follows at 550 MPa (79.8 ksi) vs 300 MPa (43.5 ksi). In exchange, 1006 is the more ductile: elongation 30% versus 12% for C17C, and C17C is harder (160 HB vs 86 HB). 1006 runs hotter in service (400°C vs 300°C continuous) and 1006 conducts heat better (65 W/m·K vs 51 W/m·K). On the shop floor, C17C machines more easily (good vs fair).

1006Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C17CChoose it when strength drives the design, or when the part is machined in volume.

1006 vs C17C — frequently asked

Is C17C stronger than 1006?

Yes. C17C has a typical yield strength of 450 MPa (65.3 ksi) against 170 MPa (24.7 ksi) for 1006 — about 165% more. Tensile strength is 550 MPa (79.8 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1006 or C17C?

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, 1006 or C17C?

C17C. Its machinability rates good (55/100) against fair (45/100) for 1006; for welding the order is 1006 first (excellent, 97/100) then C17C (excellent, 92/100).
