What is 1022 Normalized?
1022 Normalized is 1022 heat treated to Normalized — pick for uniform fine-grain structure and better toughness/consistency before machining, carburizing or in welded structures. 1022 Normalized has a yield strength of 310 MPa (45 ksi) and a tensile strength of 455 MPa (66 ksi) — weaker than 83% of steel grades. Elongation at break is 32% and the elastic modulus is 205 GPa (29.7 Msi). 1022 Normalized has a density of 7.87 g/cm³ (0.284 lb/in³), heavier than 91% of steel grades. It melts at 1,425°C (2,597 °F).

Other 1022 tempers and conditions
1022 is also supplied in 5 other conditions. The full side-by-side table is on the 1022 overview.
- HRDefaultCheapest and most stocked form; pick for weldments, machined parts with generous stock allowance, and blanks to be carburized.235 MPa yield · 121 HB
- CarburizedChoose when a wear-resistant hard case (58–62 HRC) over a tough low-carbon core is needed, e.g. pins, bushings, light gears, self-drilling screws.490 MPa yield · 60 HRC
- CDPick for straight, on-size bright bar going straight to turning/milling or to screw-machine work with better chip control.400 MPa yield · 137 HB
- CRChoose for stamped, formed or cold-headed sheet parts needing a clean surface and tighter thickness tolerance.380 MPa yield · 135 HB
- NormalizedPick for uniform fine-grain structure and better toughness/consistency before machining, carburizing or in welded structures.310 MPa yield · 131 HB
- AnnealedUse when maximum ductility for severe cold forming, deep drawing or stress relief after heavy cold work is required.275 MPa yield · 111 HB
Working with 1022 Normalized
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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| CSAE J403 / ASTM A29 grade 1022 | 0.18 – 0.23 | 0.21 |
| Mn | 0.7 – 1 | 0.85 |

| S0.035 max for SAE J403 non-resulfurized wire | ≤ 0.05 | 0.03 |
| Sinot specified for all product forms; typical for killed steel | 0.15 – 0.35 | 0.25 |

1022 Normalized — frequently asked
What is 1022 Normalized used for?
1022 Normalized is typically used for fasteners, pinion shafts and light forgings. In short: cold-heading carbon bar.
What is the yield strength of 1022 Normalized?
1022 Normalized has a typical yield strength of 310 MPa (45 ksi) and a tensile strength of 455 MPa (66 ksi) — weaker than 83% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is 1022 Normalized easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% 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 Normalized be welded?
Yes — weldability is rated excellent (92/100). 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 Normalized 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 Normalized?
1022 Normalized 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.
