DC01, DC02, DC03, DC04 are steel grades of European standard DIN EN 10130, 10209 and DIN 1623, which are specified cold rolled steel. The grades are classified according to the maximum permissible yield strength.

DC01/DC02/DC03/DC04 Kaltgewalzte Stahlplatte

DC01, DC02, DC03, DC04 sind Stahlsorten der europäischen Normen DIN EN 10130, 10209 und DIN 1623, die als kaltgewalzter Stahl spezifiziert sind. Die Sorten werden nach der maximal zulässigen Streckgrenze klassifiziert.

Carbon Steel: Properties, Production, Examples and Applications

Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.

Types of carbon steel and their properties

Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:

Carbon content (wt.%)	Microstructure	Properties	Examples
Low-carbon steel	< 0.25	Ferrite, pearlite	Low hardness and cost. High ductility, toughness, machinability and weldability	AISI 304, ASTM A815, AISI 316L
Medium-carbon steel	0.25 – 0.60	Martensite	Low hardenability, medium strength, ductility and toughness	AISI 409, ASTM A29, SCM435
High-carbon steel	0.60 – 1.25	Pearlite	High hardness, strength, low ductility	AISI 440C, EN 10088-3

PRODUKTDETAILS

DC01/DC02/DC03/DC04
Cold Rolled Steel Plate

DC
steel plates have high tensile strength and elongation, giving them good
processing properties during the manufacturing process and is easy to bend,
stamp, form and weld. This makes DC steel plates widely used in the
manufacturing of automotive parts, home appliances, construction and other
parts that require high strength and precision. DC steel plates’ s low carbon content gives
them excellent weldability and machinability. They can be processed through
various welding and cutting processes, such as arc welding, gas shielded
welding, laser cutting, etc., to meet the needs of material processing
performance in different fields. Lastly, the carbon emission is low and meets
the requirements of environmental protection and sustainable development.
