What is DC06 cold rolled steel?
DC06 cold rolled steel is an extra-deep drawing grade under the European EN 10130 standard. It is engineered to provide extremely high ductility, low yield strength and excellent forming performance, making it ideal for complex stamping and shaping operations. With smooth and uniform surface quality, DC06 steel is widely used in automotive body panels, high-end appliance casings and precision metal housings.

Why Manufacturers Upgrade from DC01 to DC06?
Customers who initially selected DC01 cold rolled steel often switch to DC06 because production issues-such as tearing, unstable forming and excessive tool wear-can be eliminated with DC06. Although DC06 steel price is slightly higher, reduced rejection rates and improved productivity lead to lower final cost per part, especially for automotive and home appliance industries.
Our company can also supply the following cold-rolled steel grades:
DC01 – Designed for basic forming processes such as bending, embossing, beading and standard drawing operations.
DC03 – Intended for more demanding forming applications, including deep drawing and more complex profiling.
DC04 – Suitable for applications requiring high levels of formability.
DC05 – A deep-drawing grade developed to meet very high forming requirements.
DC06 – A special deep-drawing grade engineered for the highest demands in cold forming.
DC07 – An ultra deep-drawing grade tailored for extreme and highly challenging forming operations.
FAQ
Q: What is DC06 cold-rolled steel?
A: DC06 is an ultra-deep drawing grade low-carbon soft steel defined by the European standard EN 10130. It belongs to the titanium-alloyed IF (interstitial-free) steel category and is known for its excellent cold formability and ductility, making it one of the highest-performing steels in terms of formability among cold-rolled sheets.
Q: What are the main characteristics of DC06?
A: Key characteristics include extremely low carbon content (typically a maximum of 0.01%), excellent ductility and deep drawing performance, and a smooth, clean surface finish. It also exhibits good dimensional stability and uniformity.
Q: What are the differences between DC06 and DC04?
A: DC06 is an ultra-deep drawing grade, possessing better formability and lower yield strength than DC04 (deep drawing grade). DC06 is suitable for manufacturing the most complex, large parts requiring the highest deformation capabilities, while DC04 is suitable for medium to complex deep-drawn parts.
