Steel DC06-LC
Supply condition
EN DC06
LC = annealed last (not skin-passed), maximum softness
Ordered when the very lowest yield and no roughness imprint are needed; must be formed promptly and can show slight stretcher-strain risk on non-IF grades (IF chemistry makes DC06 essentially non-aging).

Hot-dip galvanized extra-deep-drawing sheet | Ordered when heavier zinc (Z100–Z275) corrosion protection is required; zinc layer slightly raises friction and reduces the achievable draw ratio versus bare DC06. | 150 | 300 | 41 | 88 HB | 13 % IACS |
Electrolytically zinc coated (EN 10152), e.g. ZE25/25 | Choose for painted automotive body panels needing corrosion protection with the smoothest coated surface; thin zinc layer keeps deep-drawing behaviour almost unchanged. | 155 | 305 | 41 | 90 HB | 13 % IACS |
What is DC06-LC?
DC06-LC is DC06 supplied in the LC condition — ordered when the very lowest yield and no roughness imprint are needed; must be formed promptly and can show slight stretcher-strain risk on non-IF grades (IF chemistry makes DC06 essentially non-aging). DC06-LC has a yield strength of 130 MPa (18.9 ksi) and a tensile strength of 285 MPa (41.3 ksi) — weaker than 100% of steel grades. Elongation at break is 45% and the elastic modulus is 210 GPa (30.5 Msi). DC06-LC has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,500°C (2,732 °F). CR is the default condition FabDigit quotes; LC is available on request or by drawing note.

Working with DC06-LC
Is DC06 easy to machine?
Very soft and gummy — use sharp positive-rake tools, high speed and flood coolant to avoid burrs and built-up edge; blanking and laser cutting are preferred over milling.
Can DC06 be welded?
Excellent for resistance spot, MAG and laser welding thanks to ultra-low C, P, S; zinc-coated variants need higher electrode force/current and fume extraction.
Can DC06 be formed, bent or molded?
Best-in-class deep drawing (r₉₀ ≥ 1.8, n₉₀ ≥ 0.22, non-aging) — multi-stage draws, hemming and stretch forming succeed without intermediate annealing; watch low dent resistance and springback-free but low-strength parts.
What surface finishes work on DC06?
Takes phosphating, e-coat and powder paint readily; bare sheet must be oiled or coated immediately as it rusts fast; electro- or hot-dip zinc plus e-coat is the standard automotive system.

DC06-LC — frequently asked
What is DC06-LC used for?
DC06-LC is typically used for automotive body panels, complex stampings and appliance shells. In short: highest-formability DC grade; non-aging IF steel; class-A panel surface.
What is the yield strength of DC06-LC?
DC06-LC has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 285 MPa (41.3 ksi) — weaker than 100% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is DC06-LC easy to machine?
Not especially — machinability is rated fair (40/100, worse than 77% of steel grades). Very soft and gummy — use sharp positive-rake tools, high speed and flood coolant to avoid burrs and built-up edge; blanking and laser cutting are preferred over milling.
Can DC06-LC be welded?
Yes — weldability is rated excellent (96/100). Excellent for resistance spot, MAG and laser welding thanks to ultra-low C, P, S; zinc-coated variants need higher electrode force/current and fume extraction.
What surface finishes work on DC06-LC?
Takes phosphating, e-coat and powder paint readily; bare sheet must be oiled or coated immediately as it rusts fast; electro- or hot-dip zinc plus e-coat is the standard automotive system.
Can DC06-LC be formed, bent or molded?
Best-in-class deep drawing (r₉₀ ≥ 1.8, n₉₀ ≥ 0.22, non-aging) — multi-stage draws, hemming and stretch forming succeed without intermediate annealing; watch low dent resistance and springback-free but low-strength parts.
What is the maximum service temperature of DC06-LC?
DC06-LC is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between DC06-CR and DC06-LC?
CR is the default condition — standard stock condition: continuous-annealed and skin-passed coil/sheet, non-aging for 6 months, for general deep-drawn body and appliance panels. LC: ordered when the very lowest yield and no roughness imprint are needed; must be formed promptly and can show slight stretcher-strain risk on non-IF grades (IF chemistry makes DC06 essentially non-aging). Yield strength is 150 MPa in CR versus 130 MPa in LC.
