Bobina de acero laminado en frío 1008

1008 carbon steel coil is primarily used in extruded, cold headed, cold upset, and cold pressed parts and forms. 1008 in the cold rolled condition is used for exposed or unexposed parts where bending, moderate drawing, forming and welding may be involved.

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

DETALLES DEL PRODUCTO

1008
Cold Rolled Steel Coil

1008
cold rolled steel coil contains about 1.2% manganese and
0.4% silicon. There are also nickel, aluminium, chromium, copper and molybdenum present in
small quantities in the carbon steels. AISI 1008 carbon steel coil has
excellent weldability, which includes projection, butt, spot and fusion, and
brazeability. 1008
cold rolled steel coil is mainly used in
automobile, printed metal pail, building, building materials, and bicycle,
etc. Besides, it
is the best material to manufacture organic coated strip.
