What is C10C?
C10C is a low-carbon non-alloy steel of about 0.07–0.13 % C to EN 10263 (1.0214, equivalent to Ck10, 1010 and 10), produced specifically for cold heading and cold extrusion. Its ductility takes severe multi-blow upsetting, and it is stocked as wire, rod and coil for fastener manufacture, with roughly 400 MPa yield, 470 MPa tensile, 12 % elongation, 140 HB and 76 HRB in the cold-worked default state. Machinability is modest (score 50) and the bare surface has no corrosion resistance, so plating or phosphating is required. C15C is the usual choice when more strength is needed after forming. C10C 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). C10C has a yield strength of 400 MPa (58 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 60% of steel grades. Elongation at break is 12% and the elastic modulus is 207 GPa (30 Msi).

Working with C10C
Is C10C easy to machine?
Soft and gummy — expect stringy chips and built-up edge; use sharp positive-rake tooling, high speed and generous coolant, or specify a resulfurized grade if turning dominates.
Can C10C be welded?
Excellent weldability by all arc, resistance and projection processes; carbon equivalent ~0.20 so no preheat or PWHT needed in normal sections.
Can C10C be formed, bent or molded?
Designed for severe multi-blow cold heading and cold extrusion; use +AC or +AC+C with phosphate/soap or polymer lubricant for high upset ratios, and consider intermediate stress-relief for heavy reductions.

What surface finishes work on C10C?
No corrosion resistance in the bare state — zinc or zinc-nickel electroplate (with baking against hydrogen embrittlement), hot-dip galvanize, mechanical zinc, or phosphate-and-oil; takes paint and plating readily.

C10C — frequently asked
What is C10C used for?
C10C is typically used for cold-formed bolts and screws, rivets, cold-extruded fasteners and wire and rod products. In short: baseline cold-heading steel; weldability score 95; highest ductility in family.
What is the yield strength of C10C?
C10C has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 60% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is C10C easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 53% of steel grades). Soft and gummy — expect stringy chips and built-up edge; use sharp positive-rake tooling, high speed and generous coolant, or specify a resulfurized grade if turning dominates.
Can C10C be welded?
Yes — weldability is rated excellent (95/100). Excellent weldability by all arc, resistance and projection processes; carbon equivalent ~0.20 so no preheat or PWHT needed in normal sections.
What surface finishes work on C10C?
No corrosion resistance in the bare state — zinc or zinc-nickel electroplate (with baking against hydrogen embrittlement), hot-dip galvanize, mechanical zinc, or phosphate-and-oil; takes paint and plating readily.
Can C10C be formed, bent or molded?
Designed for severe multi-blow cold heading and cold extrusion; use +AC or +AC+C with phosphate/soap or polymer lubricant for high upset ratios, and consider intermediate stress-relief for heavy reductions.
What is the maximum service temperature of C10C?
C10C 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 C10C +C and C10C-CH?
+C is the default condition — standard stock condition: drawn wire/bar with good size tolerance, straightness and moderate strength for general cold-headed fasteners. CH: applied after cold forming when a wear-resistant hard case over a tough low-strength core is required (pins, small gears, self-drilling screws). Yield strength is 400 MPa in +C versus 400 MPa in CH.
