1020 Hot Rolled Steel

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.

The term steel refers to iron whereby 0.02 to 1.7% carbon has been added. It is used commonly in the manufacturing of automobiles, homes, cutlery, appliances and magnetic cores. Steel does however, have poor corrosion resistance. There are many different types of steel and various alloys and applications for each type. 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.

1020 Hot Rolled Steel is a very commonly used plain carbon steel. It has a small amount of carbon content, typically 0.20% with approximately0.50% manganese. Its strength and ductility provides a great combination for a variety of manufacturing opportunities and it may be carburized or hardened.

1020 Hot Rolled Steel is used in simple structural applications.
