BFS Metals Carbon Supplies

Grades of Carbon & Alloy Steel We Supply

There are four types of carbon steel based on the amount of carbon present in the alloy. Lower carbon steels are much softer and more easily formed, and steels with a higher carbon content are stronger but less ductile, and they become more difficult to machine and weld. Check below for the types of carbon steel BFS Metals supplies:

  • Low Carbon Steel – Composition of 0.05%-0.25% carbon and up to 0.4% manganese. Known as mild steel, it is a low-cost material that is easy to shape. While not as strong as higher-carbon steels, carburizing can increase its surface hardness.
  • Medium Carbon Steel – Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong, with long-wearing properties.
  • High Carbon Steel – Composition of 0.55%-0.95% carbon, with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.
  • Very High Carbon Steel - Composition of 0.96%-2.1% carbon. It is high carbon content makes it an extremely strong material. Due to it's brittleness, this grade requires extra special handling.
