AISI 1008 Alloy Is A Low-Carbon Steel With Excellent Formability, Weldability, And Machinability.

AISI 1008 Alloy is a low-carbon steel widely used for its excellent formability, weldability, and machinability. It is characterized by its low carbon content, which provides a balance of strength, ductility, and toughness, making it suitable for a variety of applications, including automotive and structural components.

Chemical Composition:

AISI 1008 Alloy includes the following key elements:

• Carbon (C): 0.08-0.13% – The low carbon content ensures good formability and ductility while keeping strength moderate.
• Manganese (Mn): 0.30-0.60% – Manganese enhances hardness and tensile strength, and aids in the deoxidation process during steelmaking.
• Silicon (Si): ≤0.35% – Silicon contributes to the steel's deoxidization and overall mechanical properties.
• Phosphorus (P): ≤0.04% – Low phosphorus content helps maintain the steel's toughness and reduces brittleness.
• Sulfur (S): ≤0.05% – Sulfur is kept low to minimize inclusions and improve machinability and overall material strength.

Mechanical Properties:

AISI 1008 Alloy is known for its good mechanical properties suited for various applications:

• Tensile Strength: 340-440 MPa – The tensile strength ensures the material can withstand moderate pulling or stretching forces.
• Yield Strength: ≥205 MPa – The yield strength indicates the alloy's ability to resist deformation under stress, providing reliability in structural applications.
• Elongation: ≥35% – The high elongation percentage demonstrates excellent ductility, allowing the material to be easily formed and shaped.
• Density: Approximately 7.85 g/cm³ – Typical for low-carbon steels, providing a good balance between strength and weight.
• Hardness: HB 80-100 – The hardness range supports good machinability and surface finish, making it suitable for various fabrication processes.
