| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Spheroidize annealed | Softest, most ductile state — choose for severe multi-station cold extrusion and deep upsetting. | 205 | 330 | 36 | 100 HB | — |
Annealed | General softening anneal when full spheroidization is not required, e.g. before moderate upsetting or re-drawing. | 215 | 350 | 33 | 105 HB | — |
Hot rolled | Mill-delivered hot-rolled coil for further drawing, annealing or light upsetting; cheapest starting condition. | 240 | 380 | 30 | 110 HB | — |
Lightly drawn / sized | Small reduction only to clean surface and hold diameter while keeping near-annealed ductility for heavy heading. | 300 | 400 | 20 | 118 HB | 11.5 % IACS |
+AC+CDefault Spheroidize annealed and cold drawn | Standard cold-heading wire delivery: soft spheroidized core with drawn size accuracy and phosphate/soap coating — default choice for fastener heading. | 360 | 440 | 14 | 128 HB | — |
Carburized and hardened | Applied to the finished cold-formed part when a hard wear-resistant case (typ. 0.1–0.6 mm) over a tough soft core is needed. | 360 | 550 | 12 | 60 HRC | — |
Hot rolled then cold drawn | Bright cold-drawn wire/bar with higher strength and good size/finish tolerance; for light heading, rivets and machined parts. | 440 | 520 | 10 | 150 HB | — |
What is C10E2C?
C10E2C is the special-quality, cold-heading version of C10E (1.1122) with tightened chemistry and surface controls, supplied mainly as wire and rod for cold forming and cross-referenced to 1010 and 10. Engineers specify it where multi-blow heading and cold extrusion demand consistent ductility and clean surface; in the default condition it gives 360 MPa yield, 440 MPa tensile, 14 % elongation and about 128 HB (72 HRB), with formability rated 93/100 and weldability 92/100. Conditions on file include +U, +A, +AC, +U+C, +AC+C, +LC and CH. Machinability is only 52/100 and the grade has no corrosion resistance; C15E2C is the alternative when a harder case or higher core strength is needed. C10E2C has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,495°C (2,723 °F). C10E2C has a yield strength of 360 MPa (52.2 ksi) and a tensile strength of 440 MPa (63.8 ksi) — weaker than 72% of steel grades. Elongation at break is 14% and the elastic modulus is 205 GPa (29.7 Msi).

Working with C10E2C
Is C10E2C easy to machine?
Gummy and prone to built-up edge in the annealed state — use sharp positive-rake tools, high speed and generous coolant; cold-drawn bar machines noticeably better than annealed wire.
Can C10E2C be welded?
Carbon equivalent ≈0.15, so all arc, resistance and projection welding processes work without preheat or post-weld heat treatment.
Can C10E2C be formed, bent or molded?
Excellent multi-blow cold heading and cold extrusion when supplied spheroidized with phosphate/soap or polymer lubricant; keep reductions per station within the wire's RA capability to avoid head cracks.

What surface finishes work on C10E2C?
No natural corrosion protection — specify zinc or zinc-nickel electroplating, mechanical galvanizing, zinc flake (Dacromet/Geomet), phosphate + oil or black oxide; watch hydrogen embrittlement rules only if case hardened.

C10E2C — frequently asked
What is C10E2C used for?
C10E2C is typically used for cold-headed bolts, rivets, wire products and small precision cold-formed parts. In short: cold-heading special quality; top formability in family; fastener wire and rod grade.
What is the yield strength of C10E2C?
C10E2C has a typical yield strength of 360 MPa (52.2 ksi) and a tensile strength of 440 MPa (63.8 ksi) — weaker than 72% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is C10E2C easy to machine?
Reasonably — machinability is rated fair (52/100, better than 52% of steel grades). Gummy and prone to built-up edge in the annealed state — use sharp positive-rake tools, high speed and generous coolant; cold-drawn bar machines noticeably better than annealed wire.
Can C10E2C be welded?
Yes — weldability is rated excellent (92/100). Carbon equivalent ≈0.15, so all arc, resistance and projection welding processes work without preheat or post-weld heat treatment.

Excellent multi-blow cold heading and cold extrusion when supplied spheroidized with phosphate/soap or polymer lubricant; keep reductions per station within the wire's RA capability to avoid head cracks.
What is the maximum service temperature of C10E2C?
C10E2C is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C10E2C +AC+C and C10E2C-CH?
+AC+C is the default condition — standard cold-heading wire delivery: soft spheroidized core with drawn size accuracy and phosphate/soap coating — default choice for fastener heading. CH: applied to the finished cold-formed part when a hard wear-resistant case (typ. 0.1–0.6 mm) over a tough soft core is needed. Yield strength is 360 MPa in +AC+C versus 360 MPa in CH.
How much does C10E2C cost?
