Choose for thicker, lower-cost parts where mill scale and looser thickness tolerance are acceptable.
What is DC01-HR?
DC01-HR is DC01 supplied in the HR condition — choose for thicker, lower-cost parts where mill scale and looser thickness tolerance are acceptable. DC01-HR has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 400 MPa (58 ksi) — weaker than 94% of steel grades. Elongation at break is 27% and the elastic modulus is 210 GPa (30.5 Msi). DC01-HR 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).

Working with DC01-HR
Is DC01 easy to machine?
Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge and burrs; ideal for punching, laser and shear cutting rather than turning.
Can DC01 be welded?
Excellent with all processes (RSW, MIG, TIG, laser, spot); galvanized versions need fume extraction, higher current and often a gap or Zn-compatible wire to avoid porosity.
Can DC01 be formed, bent or molded?
Very good cold formability — bend radii down to ~0.5–1×t, deep-draw modestly (use DC03/DC04/DC06 for severe draws); watch stretcher strain lines if the skin-pass has aged.
What surface finishes work on DC01?
Bare stock must be protected immediately — zinc plating, zinc phosphate + e-coat, powder coat or oil; galvanized sheet takes paint after a chromate/phosphate or Zn-compatible primer.
DC01 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.

|---|---|---|
| CEN 10130 ladle analysis max | ≤ 0.12 | 0.06 |
| Mn | ≤ 0.6 | 0.3 |

DC01-HR — frequently asked
What is DC01-HR used for?
DC01-HR is typically used for appliance panels, automotive body and bracket parts, electrical enclosures and cabinets, sheet metal chassis and covers, ductwork and housings and stamped brackets and clips. In short: european standard sheet.
What is the yield strength of DC01-HR?
DC01-HR has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 400 MPa (58 ksi) — weaker than 94% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is DC01-HR easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge and burrs; ideal for punching, laser and shear cutting rather than turning.
Can DC01-HR be welded?
Yes — weldability is rated excellent (95/100). Excellent with all processes (RSW, MIG, TIG, laser, spot); galvanized versions need fume extraction, higher current and often a gap or Zn-compatible wire to avoid porosity.
What surface finishes work on DC01-HR?
Bare stock must be protected immediately — zinc plating, zinc phosphate + e-coat, powder coat or oil; galvanized sheet takes paint after a chromate/phosphate or Zn-compatible primer.
Can DC01-HR be formed, bent or molded?
Very good cold formability — bend radii down to ~0.5–1×t, deep-draw modestly (use DC03/DC04/DC06 for severe draws); watch stretcher strain lines if the skin-pass has aged.
What is the maximum service temperature of DC01-HR?
DC01-HR 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 DC01-HR and DC01-CR?
HR is the default condition — choose for thicker, lower-cost parts where mill scale and looser thickness tolerance are acceptable. CR: standard stocked condition: bright, flat, tight-tolerance sheet for general bending, roll forming and light drawing. Yield strength is 250 MPa in HR versus 210 MPa in CR.
