1.What are the key features of DC01?
Low Carbon Content: A very low carbon content (typically ≤ 0.12%) is key to its excellent formability and weldability.
Excellent Formability: It is particularly well-suited for cold forming operations such as bending, deep drawing, shallow drawing, flanging, hemming, and embossing.
Good Weldability: It can be welded using most common welding methods (spot welding, seam welding, MIG/MAG welding, etc.).
Excellent Surface Quality: The cold rolling process produces a smooth, uniform surface suitable for subsequent coating (e.g., painting, electroplating).
2.What are the mechanical properties of DC01?
Yield Strength (Rp0.2): 140 - 280 MPa (Values vary depending on delivery condition and thickness)
Tensile Strength (Rm): 270 - 410 MPa (Values vary depending on delivery condition and thickness)
Elongation at Break (A80mm): ≥ 28% - 34% (Minimum value varies depending on thickness and delivery condition; higher values indicate better formability)
Hardness: Typically in the range of 40 - 85 HRB (Rockwell B scale).
3.What is the availability status of DC01?
It is typically supplied in the annealed condition (most commonly, with a temper designation such as "A" or "DC01+Z," where Z indicates annealed).
The quenched and tempered condition (with a temper designation such as "C" or "H," which provides slightly higher strength and hardness but slightly reduced formability) is also available upon request.
4.What are the application areas of DC01?
Automotive Industry: Body panels, door inner panels, seat components, fuel tanks, structural parts, etc.
Home Appliance Industry: Refrigerator, washing machine, air conditioner casings, internal brackets, panels, etc.
Construction Industry: Lightweight structural parts, doors, window frames, blinds, ceiling panels, ventilation ducts, etc.
Furniture Industry: Office furniture, filing cabinets, drawers, brackets, etc.
General Engineering: Chassis, cabinets, instrument panels, brackets, hardware, stampings, containers, etc.
5.What is the surface treatment of DC01?
Typically supplied bare (uncoated).
However, DC01 is the most commonly used substrate for coated steel sheets, including hot-dip galvanized (GI), electrogalvanized (EG), and electrogalvanized zinc-nickel (ZN).
