Steel DC01-CR
Properties of the CR condition, compared with the other DC01 tempers.
Standard stocked condition: bright, flat, tight-tolerance sheet for general bending, roll forming and light drawing.
What is DC01-CR?
DC01-CR is DC01 supplied in the CR condition — standard stocked condition: bright, flat, tight-tolerance sheet for general bending, roll forming and light drawing. DC01-CR has a yield strength of 210 MPa (30.5 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 98% of steel grades. Elongation at break is 34% and the elastic modulus is 210 GPa (30.5 Msi). DC01-CR 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). HR is the default condition FabDigit quotes; CR is available on request or by drawing note.

Other DC01 tempers and conditions
DC01 is also supplied in 3 other conditions. The full side-by-side table is on the DC01 overview.
- HRDefaultChoose for thicker, lower-cost parts where mill scale and looser thickness tolerance are acceptable.250 MPa yield · 120 HB
- GalvanizedPick for outdoor or humid service where paint alone is not enough; zinc gives sacrificial protection but limits welding, forming radius and service temperature.250 MPa yield · 105 HB
- CRStandard stocked condition: bright, flat, tight-tolerance sheet for general bending, roll forming and light drawing.210 MPa yield · 100 HB
- EGChoose when a smooth paintable surface and tight thickness control matter more than coating life — thin zinc for indoor enclosures and appliance panels.210 MPa yield · 100 HB
Working with DC01-CR
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-CR — frequently asked
What is DC01-CR used for?
DC01-CR 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-CR?
DC01-CR has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 98% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is DC01-CR 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-CR 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-CR?
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-CR 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-CR?
DC01-CR 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 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.
