Chromium is one of the important metal which is used to improve the following characteristics of a material.
- To increase the abrasion resistance
- To provide the better hardness
- To improve the corrosion and the oxidation resistance
- To improve the temperature resistance
- With high C resists wear and abrasion
- Manganese is used to improve the hardness and strength of the material. It also acts as a desulfurizing agent.
- Vanadium is used to refine grain size. Steels containing vanadium have a much finer grain structure than steels of similar compositions without vanadium. Vanadium is used to improve the mechanical properties of the materials such as hardness and toughness.
- Cobalt improves strength at high temperatures and magnetic permeability. It contributes to red hardness by hardening ferrite. It is an alloying element is certain high-speed steels. Cobalt is used in martensitic steels, where it increases hardness and tempering resistance, especially at higher temperatures.
