What is 1006-CD?
1006-CD is 1006 supplied in the CD condition — use when tighter tolerance, straightness and ~60 % higher yield are needed; ductility and formability drop. 1006-CD has a yield strength of 285 MPa (41.3 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 89% of steel grades. Elongation at break is 20% and the elastic modulus is 205 GPa (29.7 Msi). 1006-CD has a density of 7.87 g/cm³ (0.284 lb/in³), heavier than 91% of steel grades. It melts at 1,515°C (2,759 °F). HR is the default condition FabDigit quotes; CD is available on request or by drawing note.

Working with 1006-CD
Is 1006 easy to machine?
Gummy and prone to built-up edge — use sharp positive-rake tooling, high speed, generous coolant, or cold-drawn/normalized stock for better finish; consider 1215/12L14 if machining dominates.
Can 1006 be welded?
Excellent by all processes (RSW, MIG, TIG, SMAW, laser) with no preheat or PWHT; ER70S-6/E7018 filler over-matches the base metal.
Can 1006 be formed, bent or molded?
Outstanding cold formability — deep drawing, roll forming, cold heading and thread rolling; watch for stretcher strains in non-IF grades (temper roll or use a killed, aged-resistant grade).
What surface finishes work on 1006?
No corrosion resistance bare: zinc electroplate/galvanize, phosphate + e-coat or paint; also carburizes readily to a hard case (58–62 HRC) with a soft, tough core.
1006 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| CSAE/AISI 1006, heat analysis | ≤ 0.08 | 0.06 |
| Mn | ≤ 0.35 | 0.3 |
| P | ≤ 0.03 | 0.02 |

1006-CD — frequently asked
What is 1006-CD used for?
1006-CD is typically used for refrigerator panels, washing machine bodies, deep-drawn stampings, cold-headed fasteners, drawn wire, nails and chain and welded tube and pipe. In short: economical; basic shaping.
What is the yield strength of 1006-CD?
1006-CD has a typical yield strength of 285 MPa (41.3 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 89% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1006-CD easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 53% of steel grades). Gummy and prone to built-up edge — use sharp positive-rake tooling, high speed, generous coolant, or cold-drawn/normalized stock for better finish; consider 1215/12L14 if machining dominates.
Can 1006-CD be welded?
Yes — weldability is rated excellent (95/100). Excellent by all processes (RSW, MIG, TIG, SMAW, laser) with no preheat or PWHT; ER70S-6/E7018 filler over-matches the base metal.
What surface finishes work on 1006-CD?
No corrosion resistance bare: zinc electroplate/galvanize, phosphate + e-coat or paint; also carburizes readily to a hard case (58–62 HRC) with a soft, tough core.
Can 1006-CD be formed, bent or molded?
Outstanding cold formability — deep drawing, roll forming, cold heading and thread rolling; watch for stretcher strains in non-IF grades (temper roll or use a killed, aged-resistant grade).
What is the maximum service temperature of 1006-CD?
1006-CD is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1006-HR and 1006-CD?
HR is the default condition — default, cheapest form: wire rod, merchant bar and hot-rolled coil for forming, welding and re-drawing. CD: use when tighter tolerance, straightness and ~60 % higher yield are needed; ductility and formability drop. Yield strength is 170 MPa in HR versus 285 MPa in CD.
