AISI 1008 carbon steel is an extremely popular steel alloy that’s revered for its excellent formability, good weldability, and cost-effectiveness. It is often the material of choice for applications that require a balance between strength and ease of processing. This guide provides an in-depth look at AISI 1008 carbon steel, including its chemical composition, key properties, manufacturing methods, and typical applications.
At IMS, we offer the following advantages:
What is 1008 Steel?
AISI 1008 is classified as a low carbon steel that is characterized by its low hardness and excellent ductility. This steel grade is ideal for cold working processes such as bending, stamping, and deep drawing. Due to its mild nature, AISI 1008 steel is easy to weld and form, making it a favorite among fabricators and manufacturers.1008 Carbon Steel Chemical Composition
AISI 1008 carbon steel generally contains the following elements:- Carbon (C): 0.08–0.13%
- Manganese (Mn): Approximately 0.30–0.60%
- Phosphorus (P): Maximum 0.04%
- Sulfur (S): Maximum 0.05%
- Iron (Fe): Balance
1008 Steel Mechanical Properties
AISI 1008 carbon steel offers the perfect combination of formability, weldability, and cost-effectiveness, making it a versatile choice for many manufacturing and fabrication applications. Whether you need precision components for automotive use or durable parts for industrial equipment, AISI 1008 delivers consistent performance and quality. Properties include:High Ductility
The low carbon content in AISI 1008 allows it to be easily formed and shaped without cracking, making it ideal for applications involving deep drawing and extensive bending.Cold Workability
AISI 1008 carbon steel responds well to cold working processes, allowing manufacturers to achieve precise component geometries with smooth finishes.Weldability
AISI 1008 displays excellent welding characteristics and can be welded using conventional welding techniques without the need for special pre-heating or post-weld treatment, reducing production complexity and cost.Mechanical Strength
Although it is not as strong as higher carbon steels, AISI 1008 offers adequate strength for many non-critical structural and fabrication applications.Cost-Effective
Due to its low carbon content and ease of processing, AISI 1008 is a cost-effective option for a wide range of applications, while the ease of forming and minimal machining requirements contribute to reduced manufacturing costs and efficient production cycles.1008 Steel Physical Properties
