Customized Galvanized Steel High Toughness 65MN Alloy With Good Ductility

65MN Alloy Is A High-Strength Medium-Carbon Steel With Excellent Toughness And Wear Resistance.

65MN Alloy is a high-strength medium-carbon steel known for its excellent mechanical properties, making it suitable for a variety of demanding applications. This steel grade is designed to offer enhanced strength, toughness, and wear resistance, which makes it ideal for use in automotive, machinery, and structural components.

Chemical Composition:

65MN Alloy contains the following key elements:

• Carbon (C): 0.60-0.70% – The higher carbon content compared to lower carbon steels provides increased strength and hardness while maintaining good ductility and toughness.
• Manganese (Mn): 0.90-1.20% – Manganese improves tensile strength and hardness, enhances the steel's toughness, and helps in deoxidizing the steel during the manufacturing process.
• Silicon (Si): ≤0.35% – Silicon contributes to the steel’s deoxidization and improves its mechanical properties and surface finish.
• Phosphorus (P): ≤0.035% – Low phosphorus content is maintained to avoid brittleness and ensure that the alloy remains tough and ductile.
• Sulfur (S): ≤0.035% – Sulfur is kept low to reduce inclusions and improve machinability and overall material strength.

Mechanical Properties:

65MN Alloy provides a strong set of mechanical properties suitable for a range of applications:

• Tensile Strength: 800-1000 MPa – The high tensile strength makes 65MN Alloy suitable for components that must endure significant pulling or stretching forces.
• Yield Strength: ≥500 MPa – The yield strength indicates the alloy’s capacity to withstand substantial stress without permanent deformation.
• Elongation: ≥12% – The elongation percentage shows good ductility, allowing the material to be deformed and shaped without breaking, which is important for various fabrication processes.
• Density: Approximately 7.85 g/cm³ – Typical for medium-carbon steels, providing a good balance between strength and weight.
• Hardness: HB 200-240 – The hardness range supports good wear resistance and machinability, making it suitable for high-stress applications.
