High Carbon Steel Roll Forming Material Guide: Coil Sizes, Strength, Properties & Applications
High Carbon Steel Roll Forming Material
1. Overview of High Carbon Steel in Roll Forming
High carbon steel is a specialized material used in roll forming where high strength, hardness, and wear resistance are required. It typically contains between 0.6% and 1.0% carbon, making it significantly stronger and harder than mild or low carbon steel.
In roll forming, high carbon steel is less commonly used than mild or cold rolled steel due to its reduced ductility and increased difficulty in forming. However, it is essential in applications where durability, load-bearing capacity, and resistance to wear are critical.
This material is often used in precision components, springs, blades, and industrial parts where strength and hardness outweigh the need for flexibility.
2. Material Composition & Structure
High carbon steel typically consists of:
- Iron (Fe): ~97–98%
- Carbon (C): 0.6–1.0%
- Manganese (Mn): 0.3–1.0%
- Trace elements: Silicon, sulfur, phosphorus
Structure:
- Fine grain structure when processed correctly
- High hardness due to carbon content
- Can be heat treated (quenched and tempered)
- Lower ductility compared to mild steel
The higher carbon content increases strength but reduces formability.

These properties make it significantly stronger but less flexible.
5. Coating Types (If Applicable)
High carbon steel is typically supplied uncoated but may be:
- Oiled for corrosion protection
- Heat treated for hardness
- Coated after forming if required
Coatings are less common compared to structural steels.
