It is also important to note that the mechanical properties of EN 45 bright steel can be affected by factors such as temperature, stress, and the rate of loading, and can vary depending on the specific application for which it is being used.

It is a high carbon steel which have good hardenability, good wear resistance and high compressive strength.

EN 45 Bright Bar Shapes

EN 45 bright steel bar is available in a variety of shapes, including round, square, hexagonal, and flat. The most common shape is round, with diameters ranging from 3mm to 130mm. It is also available in square, hexagonal and flat shapes. The size and shape of the bar can be customized to meet the specific needs of the application.

EN 45 bright steel bar can also be produced in custom shapes and sizes to meet specific requirements. The bar is typically supplied in the as-drawn or as-rolled condition, but can also be supplied in heat-treated condition, depending on the application. Some common forms of EN 45 bright steel bar are:

Round bars

Square bars

Flat bars

Hexagonal bars

Profiles

Shafts

Spindles

It is mainly used for manufacturing gears, shafts and other mechanical components.

EN 45 Bright Bar Sizes

EN 45 bright steel bar is available in a range of sizes, with the most common size being round with diameters ranging from 3mm to 130mm. The size of the bar can vary depending on the specific application and the manufacturer.

EN 45 bright steel bar can also be produced in custom sizes to meet specific requirements. The size and shape of the bar can be customized to meet the specific needs of the application. For example, round bars can be produced with diameter of 3mm to 130mm, square bars can be produced in sizes ranging from 6mm to 130mm, and flat bars can be produced with thickness of 3mm to 25mm and widths of 20mm to 250mm.

EN 45 Bright Bar Equivalent Grades

EN 45 bright steel is an equivalent to the following grades:

SAE 1045
