Working with 1022-CD
Is 1022 easy to machine?
Machines like 1018/1020 — gummy in the annealed state, best in cold-drawn or normalized condition with sharp positive-rake tools, high speed and generous coolant; expect ~65–70 % of 1212.
Can 1022 be welded?
Readily welded by all arc, resistance and flash processes with E70XX/ER70S-x filler; carbon equivalent ≈0.40 so preheat only for heavy sections or restrained joints, and never weld after carburizing.
Can 1022 be formed, bent or molded?
Excellent cold heading, bending and drawing in HR/annealed condition; cold-drawn bar has reduced ductility and may need stress relief before severe forming.
What surface finishes work on 1022?
No inherent corrosion protection — zinc/electro-zinc plate, phosphate + oil, black oxide, paint or e-coat; polishes only to a moderate lustre and can be case-hardened before final grinding.
1022 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.

What is 1022-CD used for?
1022-CD is typically used for fasteners, pinion shafts and light forgings. In short: cold-heading carbon bar.
What is the yield strength of 1022-CD?
1022-CD has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 475 MPa (68.9 ksi) — weaker than 60% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is 1022-CD easy to machine?
Reasonably — machinability is rated good (64/100, better than 92% of steel grades). Machines like 1018/1020 — gummy in the annealed state, best in cold-drawn or normalized condition with sharp positive-rake tools, high speed and generous coolant; expect ~65–70 % of 1212.
Can 1022-CD be welded?
Yes — weldability is rated excellent (88/100). Readily welded by all arc, resistance and flash processes with E70XX/ER70S-x filler; carbon equivalent ≈0.40 so preheat only for heavy sections or restrained joints, and never weld after carburizing.

Can 1022-CD be formed, bent or molded?
Excellent cold heading, bending and drawing in HR/annealed condition; cold-drawn bar has reduced ductility and may need stress relief before severe forming.
What is the maximum service temperature of 1022-CD?
1022-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 1022-HR and 1022-CD?
HR is the default condition — cheapest and most stocked form; pick for weldments, machined parts with generous stock allowance, and blanks to be carburized. CD: pick for straight, on-size bright bar going straight to turning/milling or to screw-machine work with better chip control. Yield strength is 235 MPa in HR versus 400 MPa in CD.
Can FabDigit make parts in 1022-CD?
Yes — 1022-CD is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
