1.4871 Material Equivalent to X53CrMnNiN21-9
1.4871 is a high-performance heat-resistant stainless steel, commonly used in applications that require high temperature resistance, corrosion resistance, and high strength. It is widely used in industries such as chemical, energy, and aerospace, particularly in high-temperature components like boilers, reactors, valves, and steam pipelines.
Chemical Composition
1.4871 (also known as X53CrMnNiN21-9) has a chemical composition similar to its equivalent materials, primarily consisting of:
Chromium (Cr): 20.0–22.0%
Nickel (Ni): 3.25–4.50%
Manganese (Mn): 8.00–10.00%
Nitrogen (N): 0.38–0.50%
Carbon (C): 0.48–0.58%
Silicon (Si): Max. 0.45%
Phosphorus (P): Max. 0.045%
Sulfur (S): Max. 0.030%
Performance Characteristics
High-Temperature Resistance: The high chromium content of 1.4871 gives it excellent oxidation resistance and thermal fatigue resistance, making it suitable for prolonged exposure to high-temperature and corrosive environments.
Corrosion Resistance: The high nickel and nitrogen content enhances the material's corrosion resistance, particularly in high-temperature gases, steam, and acidic environments.
Wear Resistance: The high manganese content and hardness make this material perform excellently in high-pressure and abrasive environments, extending the lifespan of equipment.
Main Applications
Boilers and Reactors: Suitable for high-temperature, high-pressure environments in the chemical and petrochemical industries.
Valves and Pipe Components: Due to its excellent corrosion and high-temperature resistance, it is commonly used for valves, pipe fittings, and other critical components.
High-Temperature Steam Equipment: Widely used in steam systems in nuclear power plants and thermal power plants.
Equivalent Materials
X53CrMnNiN21-9: In Chinese standards, 1.4871 is designated as X53CrMnNiN21-9, indicating similar chemical composition and performance.
21-4N / SUH35: These are other international standard designations for the material, indicating similar characteristics in terms of high-temperature resistance, corrosion resistance, and strength.
