Steel DC01 Galvanized
Properties of the Galvanized condition, compared with the other DC01 tempers.
Pick for outdoor or humid service where paint alone is not enough; zinc gives sacrificial protection but limits welding, forming radius and service temperature.
What is DC01 Galvanized?
DC01 Galvanized is DC01 supplied in the Galvanized condition — pick for outdoor or humid service where paint alone is not enough; zinc gives sacrificial protection but limits welding, forming radius and service temperature. DC01 Galvanized has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 340 MPa (49.3 ksi) — weaker than 94% of steel grades. Elongation at break is 26% and the elastic modulus is 210 GPa (30.5 Msi). DC01 Galvanized 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; Galvanized is available on request or by drawing note.

Working with DC01 Galvanized
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.

DC01 Galvanized — frequently asked
What is DC01 Galvanized used for?
DC01 Galvanized 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 Galvanized?
DC01 Galvanized has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 340 MPa (49.3 ksi) — weaker than 94% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is DC01 Galvanized 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 Galvanized be welded?
Yes — weldability is rated good (65/100). 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 Galvanized?
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 Galvanized 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 Galvanized?
DC01 Galvanized is rated for continuous use to about 200°C (392 °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.
