Cold-rolled sheet steel is manufactured by further processing hot-rolled sheet through multiple stages, including pickling, cold reduction, annealing, and temper rolling.
Unlike hot-rolled steel, cold-rolled steel undergoes cold reduction to achieve precise mechanical properties, improved surface finish, consistent gauge tolerance, and excellent strip shape control. Due to these enhanced characteristics, cold-rolled sheets provide superior performance in applications that demand deep drawing as well as complex bending and forming operations.

FAQ
1. What is DC07 steel?
DC07 is a cold-rolled low-carbon steel grade manufactured according to DIN EN 10130 (uncoated) or DIN EN 10152 (electrolytically galvanized) standards. It belongs to the ultra-deep drawing steel category and possesses excellent cold forming properties.
2. What are the main characteristics of DC07?
The main characteristics of DC07 include extremely low yield strength, ultra-high total elongation, and excellent deep drawing and stretch forming capabilities.
3. What applications is DC07 suitable for?
DC07 is particularly suitable for manufacturing parts requiring extremely complex forming requirements, such as automotive side panels, oil pans, floor panels, mufflers, exhaust pipe fittings, and fuel tanks.
4. What are the differences between DC07 and DC01, DC03, DC04, DC05, and DC06?
The main difference between these grades lies in their formability. DC01 is suitable for simple forming operations; as the grade number increases, the forming requirements and capabilities also increase, with DC07 being the ultra-deep drawing steel with the strongest formability among them.
