About this product

Bright/cold drawn steel is produced using hot rolled bars or coil, the process takes place at room temperature and produces a product with excellent dimensional and machining characteristics but poor bending and forming properties.

Hot rolled material is pickled in acid to remove the surface scale, water rinsed and coated in a lubricant to aid the drawing process. The end of the material is then pointed (reduced in cross sectional area) to around 300 mm up from the end to enable it to move through a carbide die which will produce the bars dimensions. The pointed section of the material is then gripped and used to hydraulically pull the remaining material through the die, reducing the cross sectional area and increasing the length (no material is removed during this process). The typical reduction through the die is around 1.5 mm however a reduction of up to around 3 mm and several passes can be required to produce high tensile materials and complex shapes.

Bright/cold drawn materials are generally not suitable for bending and forming applications as the process imparts some work hardening stress into the material which should be countered with thermal stress relieving or annealing. The process does however greatly increase the materials tensile strength, machinability, surface finish, sectional dimensional accuracy and straightness.

Tolerances start around –0.05 mm depending on size and material application, with bar lengths available in 3 – 3.6 metres as standard. 6 metre bars are available in a limited number of sizes but are not commonly produced due to straightness tolerances and the materials end use (mainly machining and engineering). Unlike hot rolled bars of the same profile, bright/cold drawn material is still available to imperial dimensions in the UK as standard for machining or direct use.
