Product Description

Product Description

 

X53CrMnNi21-9 steel, also known as 1.4871 in the European standard, is a high-performance heat-resistant stainless steel. 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

• 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%

Mechanical Properties (In Quenched & Tempered State at 565 °C)

• Tensile Strength: 560 MPa
• Yield Strength: 885 MPa
• Elongation (δ5/%): 8%
• Hardness: >302

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.

Heat Treatment Process

• Solution Treatment: Typically heated to 1100°C, held for a period, and then air-cooled. This process improves the material's toughness and strength.
• Aging Treatment: After deformation, aging at 225°C for an extended period is used to relieve internal stresses and improve fatigue strength.
• Cooling Medium: The cooling medium should be selected based on the material's specific requirements, with water or other suitable methods being used.

Performance Characteristics and Applications

• Corrosion Resistance: It exhibits excellent resistance to corrosion, making it suitable for the chemical engineering industry. It can withstand corrosion from various acids, alkalis, and salts.
• High-Temperature Strength: It demonstrates outstanding oxidation resistance and good mechanical properties in high-temperature environments, ranging from 850°C to 1000°C.
• Thermal Processing Performance: It is easily formable by processes such as forging and welding, making it suitable for manufacturing complex-shaped components.

Due to these superior properties, X53CrMnNi21-9 steel is widely used in industries such as chemical engineering, steam turbines, nuclear energy, and also in pharmaceutical and food processing sectors
