12Cr1MoV Alloy High Strength Low Alloy Steel 7.85g/cm3

12Cr1MoV Alloy Is A High-Strength Steel With Excellent High-Temperature And Wear Resistance.

12Cr1MoV Alloy is a high-strength, low-alloy steel specifically designed for applications requiring excellent high-temperature strength and resistance to thermal fatigue. It is commonly used in the production of components subjected to high temperatures and pressures, particularly in the power generation and petrochemical industries.

Chemical Composition:

12Cr1MoV Alloy includes the following key elements:

• Carbon (C): 0.10-0.15% – The low carbon content helps to maintain the alloy's toughness and ductility while contributing to its strength.
• Manganese (Mn): 0.40-0.70% – Manganese enhances the steel's hardness and tensile strength and aids in the deoxidation process during steelmaking.
• Silicon (Si): 0.20-0.35% – Silicon improves the steel's deoxidation and overall mechanical properties.
• Chromium (Cr): 0.90-1.20% – Chromium increases the alloy's hardness, wear resistance, and high-temperature strength, contributing to its durability in harsh conditions.
• Molybdenum (Mo): 0.40-0.60% – Molybdenum enhances high-temperature strength and resistance to thermal fatigue and creep.
• Vanadium (V): 0.10-0.20% – Vanadium improves the alloy's strength, hardness, and resistance to wear and thermal shock.
• Phosphorus (P): ≤0.025% – Low phosphorus content ensures the alloy's toughness and minimizes brittleness.
• Sulfur (S): ≤0.025% – Low sulfur content reduces the risk of inclusions and enhances machinability and strength.

Mechanical Properties:

12Cr1MoV Alloy provides outstanding mechanical properties suited for high-temperature applications:

• Tensile Strength: 550-700 MPa – The high tensile strength makes it suitable for components that must withstand significant pulling or stretching forces, especially at elevated temperatures.
• Yield Strength: ≥340 MPa – This yield strength ensures the alloy’s ability to resist deformation under stress, critical for maintaining integrity in high-pressure environments.
• Elongation: ≥12% – The elongation percentage indicates good ductility, allowing the material to be deformed and shaped without breaking.
• Density: Approximately 7.85 g/cm³ – Typical for alloy steels, providing a balanced strength-to-weight ratio.
• Hardness: HB 200-220 – The hardness range supports good wear resistance and machinability, making it suitable for high-stress applications.

Applications:

12Cr1MoV Alloy is designed for use in high-temperature and high-pressure environments:

• Power Generation: Used in the manufacture of boiler components, such as steam pipes and turbine blades, where high strength and resistance to thermal fatigue are required.
• Petrochemical Industry: Employed in the production of pressure vessels, reactors, and other components subjected to high temperatures and corrosive environments.
• Chemical Industry: Suitable for components in chemical processing equipment that need to withstand high temperatures and aggressive chemicals.
• High-Pressure Equipment: Used in the construction of pipelines, vessels, and fittings that operate under high-pressure conditions.

Summary:

12Cr1MoV Alloy is a high-strength, low-alloy steel specifically engineered for high-temperature applications. Its chemical composition, including chromium, molybdenum, and vanadium, provides excellent strength, wear resistance, and resistance to thermal fatigue. This alloy is widely used in power generation, petrochemical, and high-pressure equipment where durability and performance under extreme conditions are critical.
