Hot Rolled Bar Stock

The term steel refers to iron whereby 0.02 to 1.7% carbon has been added. There are many different types of steel and various alloys and applications for each type. It is used commonly in the manufacturing of automobiles, homes, cutlery, appliances and magnetic cores just to name a few. Generally steel is low cost and it is easy to finish with paint or other coatings. This makes steel a popular choice for many different types of products. Steel does however, have poor corrosion resistance.

Hot Rolled Bar Stock is commonly coated with a bluish-gray oxide scale that prevents rusting. Steel is however; highly corrosive and will eventually rust. Proper coatings must be used in order to provide maximum adhesion to the steel. The steel must be prevented from contacting with oxygen. There are a full range of hot rolled bar stock available in many sizes and shapes to fit your manufacturing needs.

In steel manufacturing, rolling is a forming process whereby metal materials are passed through a pair of rollers. There are different types of rolling; the most common are hot rolling and cold rolling. Rolling is classified according to the temperature of the metal rolled. Cold rolling is the process that occurs when the metal is below its recrystallization temperature. When the metal is higher than its recrystallization temperature it is referred to as hot rolling.

The numeric system that describes types of steel helps to determine the alloying ingredients by the first two digits of the alloy number, and the last two digits refer to the carbon content. Generally, as carbon is added, machinability and weldability decreases but strength increases.
