Steel 1060-CD
Properties of the CD condition, compared with the other 1060 tempers.
Choose for bright, straight, close-tolerance bar with higher yield than hot rolled and good as-machined finish; residual stress can cause bow after heavy machining.
What is 1060-CD?
1060-CD is 1060 supplied in the CD condition — choose for bright, straight, close-tolerance bar with higher yield than hot rolled and good as-machined finish; residual stress can cause bow after heavy machining. 1060-CD has a yield strength of 670 MPa (97.2 ksi) and a tensile strength of 775 MPa (112 ksi) — stronger than 80% of steel grades. Elongation at break is 10% and the elastic modulus is 205 GPa (29.7 Msi). 1060-CD has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,400°C (2,552 °F). HR is the default condition FabDigit quotes; CD is available on request or by drawing note.

Working with 1060-CD
Is 1060 easy to machine?
Machine in the annealed or normalized state with rigid setups, sharp carbide or coated-carbide tooling, moderate speed and generous coolant; above ~35 HRC switch to grinding or ceramic/CBN tooling.
Can 1060 be welded?
Poor weldability (CE ≈ 0.7–0.8): preheat 200–300 °C, use low-hydrogen consumables, keep interpass heat, and post-weld stress relieve/temper immediately or expect underbead cracking.
Can 1060 be formed, bent or molded?
Cold form only in the annealed/spheroidized state and with generous bend radii; hot form 850–1100 °C, then normalize — heavy cold work needs intermediate anneals.
What surface finishes work on 1060?
No inherent corrosion resistance — oil, black oxide, phosphate, zinc plate, hard chrome or paint; hardened surfaces polish and hold a fine grind, and induction hardening plus grinding is common for wear surfaces.

1060-CD — frequently asked
What is 1060-CD used for?
1060-CD is typically used for coil and leaf springs, knife blanks, wear plates, hand tools, shafts and agricultural blades and tines. In short: medium-high carbon bar.
What is the yield strength of 1060-CD?
1060-CD has a typical yield strength of 670 MPa (97.2 ksi) and a tensile strength of 775 MPa (112 ksi) — stronger than 80% of steel grades. Strength varies by condition: see the 9 listed tempers.
Is 1060-CD easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 53% of steel grades). Machine in the annealed or normalized state with rigid setups, sharp carbide or coated-carbide tooling, moderate speed and generous coolant; above ~35 HRC switch to grinding or ceramic/CBN tooling.
Can 1060-CD be welded?
Not readily — weldability is rated poor (25/100). Poor weldability (CE ≈ 0.7–0.8): preheat 200–300 °C, use low-hydrogen consumables, keep interpass heat, and post-weld stress relieve/temper immediately or expect underbead cracking.
What surface finishes work on 1060-CD?
No inherent corrosion resistance — oil, black oxide, phosphate, zinc plate, hard chrome or paint; hardened surfaces polish and hold a fine grind, and induction hardening plus grinding is common for wear surfaces.
Can 1060-CD be formed, bent or molded?
Cold form only in the annealed/spheroidized state and with generous bend radii; hot form 850–1100 °C, then normalize — heavy cold work needs intermediate anneals.
What is the maximum service temperature of 1060-CD?
1060-CD is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1060-HR and 1060-HDW?
HR is the default condition — default stock form for bar, plate and flat: cheapest, adequate strength, to be machined and then heat treated if hardness is needed. HDW: wire condition for coil and tension springs wound cold and only stress-relieved; strength rises sharply as diameter falls. Yield strength is 370 MPa in HR versus 1,300 MPa in HDW.
