Application:

In the petrochemical industry, it is often used to manufacture components of heat exchangers, high-temperature pipelines and reaction vessels. In the power industry, it can be used to manufacture high-temperature components such as superheater tubes and reheater tubes. In the field of food processing, it is suitable for manufacturing equipment parts with high requirements for hygiene and corrosion resistance. In the aerospace field, it can be used in engine components and high-temperature structural parts. In the pharmaceutical industry, it can be used as a material for manufacturing reactors and transmission pipelines.

Physical Properties:

1. Density: Usually around about 7.93 g/cm ³.

2. Melting Point: Around 1398 – 1427 ° C.

3. Thermal Conductivity: Relatively low, around 16.3 W/(m · K). Lower thermal conductivity means it does not perform well in heat transfer, but has an advantage in some applications where insulation is required or temperature stability is maintained.

4. Resistivity: Higher, around 0.73 Ω · mm ²/m. Higher resistivity makes it possible that it may require special consideration in certain electrical applications.

Chemical properties:

1. Main components: contains chromium (Cr) about 17 – 19%, nickel (Ni) about 9 – 13%, and niobium (Nb) and other elements.

2. Corrosion resistance: has excellent oxidation resistance and corrosion resistance, able to resist the erosion of a variety of acids, alkalis and salt solutions. In chemical equipment, can be in contact with corrosive media for a long time without being severely corroded.

3. Oxidation resistance: can form a stable oxide layer in high temperature environment, effectively prevent further oxidation. Commonly used in high temperature heating equipment components, such as heat exchangers.

4. Stability: under normal conditions of use, the chemical composition is stable, not prone to phase change and component segregation. This guarantees the consistency and reliability of material properties.
