LOW (MILD) CARBON STEEL STRIP
Low carbon steels contains up to 0.25% Carbon contents.
The largest category of this class of steel is flat rolled products (sheet or strip),
usually in the cold rolled & annealed condition.

Application
DC01: Mainly for commercial, can only be bent and formed, and no stamping is allowed. General shaping and processing of refrigerator and other household appliances hell,oil drums,steel furniture.
DC03: Mainly for drawing quality. And it usually used to made auto parts and electrical parts, etc.
DC04: Mainly used for deep drawing and simple metal stamping parts of daily necessities, such as auto parts, electrical products and other products with high ductility requirements.
DC05 : Used for stamping high-demand products such as auto parts and electrical products. It has high tensile strength and good toughness.
DC06:Super stamping steel, is mainly used for steel plates and belts of ultra-deep drawing automobile parts
