Bobine d'acier laminé à froid 1045

1045 cold rolled steel coil is a medium carbon structural steel with good hot and cold workability and good mechanical properties. It is widely used in the industrial machinery manufacturing industry.

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 [1]. 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

DÉTAILS DU PRODUIT

1045
Cold Rolled Steel Coil

AISI
1045 is a medium carbon steel designed to be able to function in areas
requiring greater strength and hardness. This steel possesses excellent size
accuracy, concentricity, and straightness which together minimize wear in
high speed applications. AISI 1045 can be formed into turned, ground and
polished coils that
can be machined unsymmetrically with limited distortion. They are often used in the production
of gears, shafts, axles, bolts, studs and
machine parts.
