Classification
Heat resistant steel can be classified into several types based on chemical composition, microstructure and purpose Common classifications include:
Martensitic heat resistant steel: These steels are known for their high strength and hardness, as well as their ability to retain their mechanical properties at high temperatures They are often used in applications such as steam turbine blades and high-temperature machine parts.
Austenitic heat resistant steel: These steels are characterized by high temperature strength, corrosion resistance and good weldability They are widely used for making parts of furnaces, heat exchangers and other high temperature devices.
Ferritic Heat Resistant Steel: These steels have a ferritic microstructure and are known for their resistance to high temperature oxidation They are often used in applications such as automotive exhaust systems and industrial furnaces.
Precipitation Hardened Heat Resistant Steel: These steels can achieve high strength through precipitation hardening, making them suitable for high temperature applications such as aerospace components and high temperature fasteners.
