Cold rolled steel coil
Cold rolled steel coil is the abbreviation of cold-rolled plain carbon structural plate, also known as cold-rolled sheet, commonly known as the cold plate. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling steel plate thickness is less than 4mm. Due to the rolling at room temperature, do not produce iron oxide, so cold plate surface quality, high dimensional accuracy, coupled with the annealing, mechanical and technological properties are superior to hot-rolled steel sheet, in many areas, especially household electrical appliance manufacturing, has been gradually replaced with its hot-rolled steel sheet
DC01 steel (1.0330 material) is a European standard cold-rolled quality low-carbon steel flat product for cold forming. Note: DIN 1623 has been replaced by DIN EN 10130, and the designation ST12 has been replaced by DC01.
The main difference between hot and cold rolled steel is in how they are processed. Hot rolled steel is steel that has been rolled at high temperatures, while cold rolled steel is essentially hot rolled steel that is further processed in cold reduction materials
Because of its advantages over hot rolled steel, cold rolled steel is more expensive. Also, because cold rolled steel is tougher to manipulate, it's takes more time and can cost more to take it through similar processes.
DC01 Steel Properties
Low Carbon, High Toughness – With ≤0.12% carbon, DC01 resists brittleness and absorbs impact, ideal for structural and safety components.
Cold-Rolled, Smooth Surface – Precision cold rolling ensures a flawless finish, consistent thickness, and suitability for coatings.
Excellent Formability – High tensile strength and ductility allow complex shaping without cracking, reducing waste and costs.
Electroplated Zinc Protection – Uniform coatings (ZE25, ZE50, etc.) prevent rust, extending lifespan and lowering maintenance.
Strong Weldability – Low carbon enhances weld strength, ensuring durable, stable connections, even after electrogalvanizing.
Versatile Surface Grades – DC01-A and DC01-B options meet diverse quality needs, from automotive to appliance applications.
Eco-Friendly & Recyclable – Low-carbon production reduces waste and supports sustainability.

FAQ
What is DC01 steel used for?
DC01 steel is mainly used in automotive panels, appliance housings, furniture, electrical enclosures, and precision-formed components where smooth surface finish and dimensional accuracy are essential.
Is DC01 good for welding?
Yes. DC01 steel has excellent weldability due to its low carbon content, making it suitable for spot, seam, and arc welding without significant risk of cracking or distortion.
What is the difference between DC01 and DC03?
The main difference lies in formability; DC03 contains slightly lower carbon and higher elongation than DC01, allowing it to withstand deeper drawing and more complex forming operations.
