What it solves: predictable forming, paint-ready surface, and stable weldability—so your press line runs quieter, coating defects drop, and first-pass yield improves.
Who it’s for: automotive inners/brackets, appliance shells, HVAC ducting, electrical enclosures, shelving, and light fabrication.
Why now: DC01 offers a tighter thickness window and cleaner surface versus general carbon steel sheet—ideal when OEE and cosmetic quality are KPIs.

PRODUCT DESCRIPTION
DC01 is the “steady hand” in cold-rolled mild steels: low carbon for effortless shaping, a satin-matte finish that takes paint evenly, and mechanicals tuned for repeatability. On the shop floor, blanks feed flat, the die closes with less chatter, and edges shear with a clean, almost glassy feel. Weld puddles wet out smoothly with minimal spatter; powder, e-coat, and wet paint level consistently with fewer fish-eyes. If you’ve been juggling mixed heats or inconsistent imports, moving to a controlled DC01 program typically cuts rework loops and stabilizes takt time—small deltas that add up across thousands of parts.

Fewer paint defects, faster PPAPs
Skin-pass finish + controlled roughness deliver uniform coating hold-out.
Result: fewer touch-ups, quicker correlation from lab panels to line runs.
Tighter thickness control, safer forming window
Stable gauge reduces draw variability and spring-back guesswork.
Result: quicker die-tryout, lower scrap in multi-cavity tools.
Low-carbon weldability, cleaner beads
Predictable spot/MIG parameters with low spatter.
Result: less post-grind, faster downstream assembly.
Supply assurance for phased ramps
30,000 t/month capacity + 5-ton MOQ.
Result: pilot, SOP, and surge protection without bloating inventory.
1) Standards & Equivalents
EN 10130 DC01 (1.0330); legacy St12/FeP01.
Electro-galvanized variant: DC01+ZE (EN 10152) when corrosion pre-coating is needed.
Adjacent grades to extend formability margin: DC03–DC07.
2) Chemistry & Mechanicals (typical design screen)
Max C ≤ 0.12, Mn ≤ 0.60; YS up to 280 MPa; TS 270–410 MPa; A80 ≥ 28%.
Use these for early DFM; lock final values in PO/spec.
3) Surface Classes & Finish
Class A/B for cosmetic requirements; finish options from extra-smooth to matte.
Supply state: oiled / non-oiled / DOS per your paint line practice.
4) Dimensional Tolerances (EN 10131 practice)
Cold-rolled sheets in this class typically target narrow thickness tolerances (e.g., ~±0.06 mm at 1.0 mm as a working cue).
Final tolerances to follow EN tables and PO agreement by thickness/width.
5) Processing Guidance
Forming: bending, beading, simple draw; for aggressive draws, consider DC03+.
Cutting: 5–7% clearance helps keep burr minimal and preserves the surface.
Welding: consistent spot/MIG response; standard parameters by thickness.
Coating: degrease per system; surface accepts powder, e-coat, and wet paint.
Storage: keep dry; FIFO; long storage can slightly age low-carbon formability.
6) Applications
Automotive inner panels/brackets, appliance housings, HVAC, shelving, enclosures, light-gauge fabrication.
7) Commercials Buyers Expect
MOQ options, free samples, coil weights 2–20 t, packaging for export (edge protection + VCI), certificates, and processing services (slitting, cutting, punching, decoiling).
Forming: Start air-bend radii ≈1.0–1.5×t; manage binder force and lube to control draw-in. Skin-pass improves flatness and reduces stretcher-strain marks.
Cutting: Keep tooling sharp; use conservative clearance to maintain a crisp, satin edge.
Welding: Spot weld schedules are stable; MIG beads lay smooth with predictable HAZ—good news for cosmetic panels.
Coating: Oil selection should match your pretreatment; non-oiled is fine for tightly controlled in-house lines, DOS for longer transit or humid lanes.
Storage: Dry, covered, strapped; prioritize recent heats for the tightest forming jobs.
Packaging: seaworthy wrap, edge protectors, VCI film/paper; coil IDs and weights aligned to typical decoilers (2–20 t).
Tolerances: supplied per EN 10131; confirm restricted class if your dies are tight.
Surface: A/B cosmetic classes; extra-smooth/smooth/matt per RA requirement; oiled/non-oiled/DOS to balance corrosion vs. paint prep.
Operational reliability: large monthly capacity keeps your line fed through pilot, ramp, and seasonal peaks.
Low barrier to start: 5-ton MOQ + free samples accelerate PPAP and fixtures buy-off.
Surface discipline: multiple oiling options to match your coating route, cutting your pre-paint prep time.
Standards fluency: multi-standard documentation (AISI/ASTM/JIS/SUS/DIN/GB) smooths cross-plant qualification.
Support that speaks “press & paint”: commercial + process engineers available from RFQ to SOP.
Q1. Is DC01 equivalent to SPCC/CR1?
They’re parallel concepts under different systems. DC01 (EN 10130) broadly aligns with common commercial cold-rolled mild steels like CR1 or JIS SPCC in intent and use. Always validate per your drawing’s thickness tolerance, surface class, and coating route before substitution.
Q2. How deep can I draw with DC01?
DC01 handles bending, coining, beading, and simple draws well. For aggressive draws (tight radii, high wall heights, complex bead patterns), step to DC03–DC06 to gain elongation and lower yield. That approach typically shortens tool try-outs and reduces split/scratch risk.
Q3. Should I order oiled or non-oiled?
If your pretreatment is tightly controlled and transit is short, non-oiled can save cleaning steps. For longer logistics chains or humid climates, specify DOS oiled to reduce corrosion risk without hurting paint adhesion—just align with your cleaning chemistry.
Q4. What about thickness tolerance for nesting/dies?
Use EN 10131 as the baseline. Many buyers designing around 1.0-mm DC01 assume ≈±0.06 mm as a working cue, then lock the exact tolerance in the PO to match their dies and cosmetic targets.
Q5. Can you supply DC01+ZE (electro-galvanized)?
Yes. If you need corrosion protection before painting or want a pre-coated inner, specify DC01+ZE per EN 10152 with coating weight and surface class in the RFQ.
