DIFFERENCE BETWEEN BLACK STEEL AND BRIGHT DRAWN STEEL

Metal Man KnowsCustomers often ask us about the differences between black steel and bright drawn steel. There are some fundamental differences between these two types of metal. These differences relate to the ways these metals are processed at the mill, and not the product specification or grade.

Black Steel
Black steel is created through a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Black steel is typically cheaper than bright drawn steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with bright drawn). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to bright drawn.

Uses: Black products like black steel bars are used in the welding and construction trades to make railroad tracks and I-beams, for example. Black steel is used in situations where precise shapes and tolerances are not required.

Bright drawn
Bright drawn steel is essentially black steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term bright drawn is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products.

When referring to bar products, the term used is “cold finishing”, which usually consists of cold drawing and/or turning, grinding and polishing. This process results in higher yield points and has four main advantages:

Cold drawing increases the yield and tensile strengths, often eliminating further costly thermal treatments.
Turning gets rid of surface imperfections.
Grinding narrows the original size tolerance range.
Polishing improves surface finish.
All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to black steel.

Cold finished bars are typically harder to work with than black steel due to the increased carbon content. However, this cannot be said about bright drawn sheet and black steel sheet. With these two products, the bright drawn product has low carbon content and it is typically annealed, making it softer than black steel sheet.

Uses: Any project where tolerances, surface condition, concentricity, and straightness are the major factors.
