Introduction
Ultra-high carbon steel is a form of steel that has carbon content ranging from 1.20-2.00%. It is characterised with its high formability and superior plasticity, making it suitable for a variety of applications such as in automobiles, aerospace and construction. The production of Ultra-high carbon steel is a complex process and requires careful control of temperature and other parameters.
Composition
Ultra-high carbon steels are typically composed of iron, carbon and small amounts of manganese, silicon and sulphur. The increased carbon content of the steel increases its strength, ductility and durability.
Properties
Ultra-high carbon steels possess superior plasticity and formability which is not found in low or medium carbon steels. The steel is typically used for components that need to be formed into complex shapes such as car wheels, crankshafts and camshafts. The increased carbon content makes it more wear and tear resistant, hence increasing its longevity.
The higher carbon content also affects the welding properties of the steel, making it difficult to weld. The high carbon content also has an effect on the steel’s wear resistance – making it prone to wear especially in high temperature and pressure applications.
Production
Ultra-high carbon steels are produced using different methods such as the basic oxygen furnace, open hearth and the electric arc furnace. The steel is produced by heating the material to the required temperature in order to gain the desired properties. The high carbon content of the steel requires careful control of temperature and other parameters, such as alloy composition and oxygen content, during different stages of the production process.
Applications
Ultra-high carbon steels find a variety of applications in different industries. It is used to produce automotive components such as crankshafts, camshafts, connecting rods and valve springs. It is also used for construction parts, aerospace components and cutting tools in industrial equipment.
Conclusion
Ultra-high carbon steel is a high carbon steel with a carbon content ranging from 1.20-2.00%. The increased carbon content of the steel allows it to possess superior plasticity and formability, making it suitable for various applications such as in automobiles, aerospace and construction. The production of ultra-high carbon steel is a complex process as it requires careful control of temperature and other parameters during different stages of the process.
