SAE 1008 carbon steel

Introduction

We manufacture forging ingots, billets, and blooms in carbon steel specifically for SAE 1008, designed for very low carbon applications where excellent formability, high ductility, and easy weldability are required.

SAE 1008 is a very low carbon, unalloyed steel with approximately 0.08% carbon content. It offers superior ductility and high machinability, making it ideal for deep drawing, forming, and fabrication in automotive, packaging, and general engineering applications with low mechanical loads.

Chemical composition

Element Content (%) Function / effect
Carbon (c) 0.06 – 0.10 Provides very low strength with excellent ductility and formability
Manganese (mn) 0.30 – 0.60 Improves toughness and machinability
Phosphorus (p) 0.040 max Controlled to prevent brittleness
Sulphur (s) 0.050 max Improves machinability when controlled
Silicon (si) 0.10 – 0.30 Acts as deoxidizer and improves strength
Chromium (cr) Nil Not intentionally added
Nickel (ni) Nil Not present
Molybdenum (mo) Nil Not present
Other elements No significant alloying additions

Mechanical properties

(Properties may vary depending on section size and heat treatment conditions)

  • Tensile strength: 350 – 440 MPa
  • Yield strength: 180 – 270 MPa
  • Elongation: 30 – 40 %
  • Hardness: 100 – 130 HB

Heat treatment

  • Annealing: improves softness and formability

Why choose Sae 1008 for your application?

Sae 1008 Is Ideal For Applications That Demand Maximum Formability, Excellent Surface Quality, And Consistent Manufacturing Performance. Its Ultra-Low Carbon Content Makes The Steel Extremely Soft And Ductile, Allowing It To Withstand Deep Drawing, Bending, Stamping, And Other Severe Cold Forming Operations Without Cracking Or Failure.

The Grade Also Offers Uniform Microstructure And Good Grain Flow, Which Helps Achieve Smooth, Defect-Free Surfaces And High Dimensional Accuracy In Finished Products. This Results In Better Aesthetics And Reduced Need For Additional Finishing Operations.

Sae 1008 Provides Excellent Weldability, Making It Suitable For Fabricated And Assembled Components Without Special Heat Treatment Requirements. It Also Ensures Low Tool Wear And Easy Machining, Which Improves Production Efficiency.
