Understanding 1018 Cold Drawn Steel
What is 1018 Cold Drawn Steel?
1018 cold drawn steel is a low-carbon steel alloy that has undergone a cold working process to improve its mechanical properties and dimensional accuracy. The “1018” designation refers to its specific chemical composition, with the first two digits indicating the carbon content (0.18%) and the following two digits representing other alloying elements.
The Cold Drawing Process
The cold drawing process involves pulling steel through a series of dies to reduce its cross-sectional area. This process results in increased strength, improved surface finish, and enhanced dimensional accuracy. Cold drawing also imparts residual stresses that can improve the fatigue resistance of the steel.
Chemical Composition
The chemical composition of 1018 steel is relatively simple, consisting primarily of iron, carbon, manganese, and small amounts of other elements such as phosphorus and sulfur. This simple composition contributes to its excellent weldability and machinability.
Mechanical Properties
Strength and Durability
1018 cold drawn steel offers a good balance of strength and ductility. The cold working process increases its tensile strength and yield strength, making it suitable for applications that require a combination of toughness and hardness. This increased strength allows for the production of thinner, lighter components without compromising structural integrity.
Machinability
One of the most significant advantages of 1018 cold drawn steel is its excellent machinability. The free-machining characteristics of this material allow for easy cutting and shaping, reducing machining time and costs. This is due to the presence of sulfur and phosphorus in the steel, which act as lubricants during the machining process.
Formability
1018 steel exhibits good formability, making it suitable for various forming processes such as bending, drawing, and stamping. This property is essential for producing complex shapes and components. The cold drawing process improves the formability of the steel by breaking up the grain structure and aligning the grains in the direction of the drawing.

FAQ
What is the difference between 1018 hot rolled and cold drawn steel?
Hot rolled steel is produced by rolling steel at high temperatures, resulting in a lower strength and poorer surface finish than cold drawn steel. Cold drawn steel, on the other hand, is produced by pulling steel through dies at room temperature, resulting in higher strength, better surface finish, and improved dimensional accuracy.
Can 1018 cold drawn steel be welded?
Yes, 1018 cold drawn steel is highly weldable. However, it is important to use appropriate welding techniques and filler metals to ensure high-quality welds.
What is the heat treatment process for 1018 steel?
1018 steel can be heat treated to improve its mechanical properties. Common heat treatments include annealing, normalizing, and tempering. Annealing is used to soften the steel and relieve stresses, while normalizing is used to refine the grain structure and improve mechanical properties. Tempering is used to increase the toughness and ductility of the steel.
How does 1018 cold drawn steel compare to stainless steel?
1018 cold drawn steel is less expensive than stainless steel and offers good mechanical properties, but it is not as corrosion-resistant as stainless steel. Stainless steel is more suitable for applications that require high corrosion resistance, such as food processing equipment and marine environments.
