EN24 Alloy Steel Flats Description
EN24 is a high-performance alloy steel known for its strength, toughness, and wear resistance. It is commonly used in applications where high strength and durability are essential. Heres a detailed description of EN24 alloy steel flats:
Material Composition
- Carbon (C) 0.30% - 0.40%
- Chromium (Cr) 1.00% - 1.40%
- Nickel (Ni) 1.40% - 1.70%
- Manganese (Mn) 0.60% - 0.90%
- Silicon (Si) 0.20% - 0.35%
- Sulfur (S) Up to 0.035%
- Phosphorus (P) Up to 0.035%
Properties
- Hardness EN24 can be heat-treated to achieve a hardness range of 28 to 32 HRC (Rockwell Hardness) or higher, depending on the specific treatment and application requirements.
- Tensile Strength Offers excellent tensile strength, often exceeding 850 MPa (megapascals) after heat treatment.
- Impact Toughness Known for good impact toughness, making it suitable for high-stress applications.
- Wear Resistance Provides good wear resistance due to its alloying elements, particularly chromium and nickel.
Applications
- Automotive Components Used in the manufacturing of high-stress components like crankshafts, camshafts, and gear shafts.
- Engineering Parts Ideal for structural components such as axles, gears, and machine parts requiring high strength and durability.
- Tooling Suitable for tools and dies that require high toughness and wear resistance.
Surface Finish
- Standard Finish EN24 flats are typically supplied with a standard mill finish but can be further processed to achieve specific surface conditions, such as ground or polished surfaces.
- Custom Finishing Available in custom finishes depending on the application requirements.
Heat Treatment
- Hardening Heat to approximately 820C - 850C (1500F - 1560F) and quench in oil or water. The specific temperature and quenching medium may vary based on the required hardness.
- Tempering To achieve the desired properties and relieve internal stresses, tempering is performed at temperatures ranging from 500C - 650C (932F - 1202F), depending on the desired hardness and application.
Dimensions
- Thickness and Width Available in a variety of thicknesses and widths, tailored to meet specific project requirements.
- Length Typically offered in standard lengths, with custom lengths available upon request.
Advantages
- High Strength EN24 offers superior strength and toughness, making it suitable for demanding applications.
- Versatility Versatile in use for various engineering and automotive applications.
- Customizable Can be heat-treated and machined to specific requirements to achieve optimal performance.
EN24 alloy steel flats are a reliable choice for high-stress applications requiring both strength and durability. Their properties make them well-suited for use in automotive, engineering, and tooling applications where high performance is essential.
