7.85g/cm3 Galvanized Steel High Strength 40CR Alloy Steel Wear Resistant

40Cr Alloy Is A High-Strength Steel With Excellent Wear Resistance And Toughness.

40Cr Alloy is a high-strength, medium-carbon steel known for its excellent mechanical properties and versatility in various engineering and structural applications. This alloy is designed to offer a balance of strength, toughness, and wear resistance, making it suitable for components subjected to high stress and heavy loads.

Chemical Composition:

40Cr Alloy contains the following key elements:

• Carbon (C): 0.37-0.45% – The carbon content provides increased strength and hardness while maintaining good toughness and ductility.
• Manganese (Mn): 0.50-0.80% – Manganese improves tensile strength, hardness, and toughness. It also assists in deoxidizing the steel during production.
• Silicon (Si): ≤0.35% – Silicon enhances the steel’s deoxidization, which contributes to a cleaner alloy and improved mechanical properties.
• Chromium (Cr): 0.90-1.20% – Chromium adds to the alloy’s hardness and wear resistance, enhancing its ability to withstand abrasive conditions.
• Phosphorus (P): ≤0.035% – Low phosphorus content helps maintain the steel’s toughness and reduces the risk of brittleness.
• Sulfur (S): ≤0.035% – Sulfur is kept at a low level to minimize inclusions and improve machinability and overall strength.

Mechanical Properties:

40Cr Alloy is characterized by robust mechanical properties:

• Tensile Strength: 800-1000 MPa – High tensile strength makes it suitable for components that need to endure significant pulling or stretching forces.
• Yield Strength: ≥600 MPa – The yield strength indicates the alloy’s ability to resist deformation under stress, ensuring reliability in structural applications.
• Elongation: ≥12% – The elongation percentage demonstrates good ductility, allowing the material to be formed and shaped without breaking.
• Density: Approximately 7.85 g/cm³ – Typical for medium-carbon steels, providing a balanced strength-to-weight ratio.
• Hardness: HB 207-241 – The hardness range supports good wear resistance and machinability, making it ideal for high-stress applications.

Applications:

40Cr Alloy’s excellent mechanical properties and chemical composition make it suitable for a variety of demanding applications:

• Automotive Parts: Used in the production of engine components, crankshafts, camshafts, and gears that require high strength and wear resistance.
• Machinery Components: Ideal for parts such as shafts, spindles, and gears, which must withstand heavy loads and high stresses.
• Structural Elements: Employed in construction and structural engineering for components like beams, columns, and frames, where strength and durability are essential.
• Tools and Dies: Suitable for manufacturing tools and dies that require high hardness and resistance to wear, such as molds and cutting tools.
• General Engineering: Used in various engineering applications requiring a combination of strength, toughness, and machinability.

Summary:

40Cr Alloy is a high-strength medium-carbon steel designed to offer a robust combination of tensile strength, toughness, and wear resistance. Its balanced chemical composition and mechanical properties make it suitable for demanding applications in automotive parts, machinery components, structural elements, and tools. With its reliable performance and durability, 40Cr Alloy provides an excellent solution for a wide range of industrial uses.
