Carburising is a process widely used in the metallurgical industry to increase the surface hardness of steel. This thermochemical treatment uses a gaseous agent, known as the carburising agent, to diffuse carbon into the surface of the steel. The process typically takes place at temperatures between 850°C and 950°C. It increases the surface hardness of the steel, making it more resistant to wear and mechanical stress.
Once carburising is complete, the steel has significantly improved surface hardness. This is achieved through the combination with hardening and tempering, which give the steel surface the desired hardness. This surface hardness makes the steel more resistant to wear and mechanical stress. The treatment also improves the toughness and fatigue strength of the material, and leaves a clean, residue-free surface.
What is carburising used for?
Carburising produces extremely hard surfaces that significantly improve the material’s wear resistance. This makes the steel suitable for applications requiring greater durability and resistance to deterioration. Carburising also improves the toughness and fatigue strength of the material’s core.
Another advantage of carburising is a clean surface free of unwanted residues. This is particularly important for applications requiring a high-quality appearance.
