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).
Advantages
- Conducts heat well — 52 W/m·K (30 BTU/hr·ft·°F), better than 98% of steel grades
- Readily welded — 95/100, better than 97% of steel grades
- High electrical conductivity — 10.8 % IACS, better than 94% of steel grades
- Ductile — tolerates forming and impact — 27%, better than 86% of steel grades
- Forms and bends easily — 70/100, better than 86% of steel grades
Limitations
- Low strength — 250 MPa (36.3 ksi), worse than 94% of steel grades

Chemical & Environmental3
Corrosion resistance is not recommended (10/100), worse than 86% of steel grades.
Sustainability4
Producing a kilogram of DC01-HR takes about 25 MJ of energy and emits 2.1 kg of CO₂ — less than 82% of steel grades. Typical recycled content is 25%.
Manufacturability8
DC01-HR's machinability is good (55/100, better than 62% of steel grades); weldability excellent (95/100); formability very good (70/100).
Common Calculations5
Values are nominal handbook figures for design screening. Confirm any required mill or lot documentation when quoting.
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 |
| P | ≤ 0.05 | 0.02 |
| S | ≤ 0.05 | 0.02 |
| Sitypical for Al-killed CR sheet, not always specified | ≤ 0.05 | 0.02 |

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 2 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.
