Q:

What is 1018 steel?

A:

Quick Answer

The metal 1018 steel has a carbon content of 0.18 percent. It is the most common of the cold-rolled steels. It combines the typical traits of steel, such as ease of machining, strength and some ductility for good weldability.

Full Answer

Steel is iron with carbon and other materials added. The number indicates what elements were included in the alloy. According to OnlineMetals.com, higher carbon content leads to greater strength, but makes welding and machining the metal more difficult; however, 1018 steel is a mild steel with low carbon and is available in a variety of shapes, such as bars, rods, sheets and strips.

    What is fully killed steel?

    A:

    Fully killed steel is steel that has had all of its oxygen content removed and is typically combined with an agent before use in applications, such as casting. The four levels of steel kill include fully killed steel with all oxygen removed, semi-killed steel with the partial removal of oxygen, rimmed steel and capped steel.

  • Q:

    How is iron converted to steel?

    A:

    The element iron is converted to the alloy commonly called steel by controlling the percentage of carbon in the product, which is usually 0.25 percent to 1.5 percent of the final alloy content. The first economical method for producing steel in large quantities was the Bessemer furnace, which was invented in the mid 1850s and introduced a stream of air to the molten metal that enabled better control over the carbon content. In the modern process, high-purity oxygen is pumped into the furnace instead, which avoids adding the impurities found in ordinary air.
