Meehanite HSV Heat Resisting Cast Iron Product Information -:- For detailed product information, please contact sales. -: **Product Name:** Meehanite HSV (High-Strength, Heat-Resisting, Vanadium Alloyed) Cast Iron --- ### **1. Product Overview** Meehanite HSV is a proprietary, alloyed spheroidal graphite (SG) or ductile iron engineered for superior performance in extreme elevated-temperature and high-stress environments. Building upon the foundation of standard heat-resistant grades, the "V" designation signifies the strategic addition of **Vanadium**, which significantly enhances high-temperature tensile strength, creep resistance, and microstructural stability. This grade is specifically developed for applications where conventional high-silicon molybdenum (SiMo) ductile irons approach their performance limits. The Meehanite manufacturing process ensures precise control over the nodular graphite structure and matrix, guaranteeing the consistent and reliable properties required for critical high-heat components. --- ### **2. Chemical Composition (Typical Range)** The composition of Meehanite HSV is carefully balanced to optimize its high-temperature capabilities. The vanadium addition is its key distinguishing feature. * **Carbon (C):** 3.2 - 3.6% * **Silicon (Si):** 2.0 - 2.8% (Promotes ferrite stability and oxidation resistance). * **Manganese (Mn):** < 0.5% * **Phosphorus (P):** < 0.04% * **Sulfur (S):** < 0.015% * **Magnesium (Mg):** 0.03 - 0.06% (Nodularizing agent). * **Molybdenum (Mo):** 0.3 - 1.0% (Enhances high-temperature strength and hardenability). * **Vanadium (V):** 0.1 - 0.3% (Primary alloying element; forms stable, fine carbides that impede dislocation movement and retard creep deformation at high temperatures). * **Microstructure:** A fully ferritic matrix is typically targeted for optimal long-term heat resistance. Vanadium carbides (VC) are finely dispersed within this ferritic matrix, providing precipitation strengthening without significantly compromising ductility or thermal fatigue resistance. --- ### **3. Physical & Mechanical Properties** **A. Room Temperature Properties (As-Cast or Annealed):** * **Tensile Strength:** 500 - 600 MPa * **Yield Strength (0.2% Offset):** 350 - 420 MPa * **Elongation:** 8 - 15% * **Hardness:** 170 - 220 HB * **Impact Toughness:** Good (Superior to flake graphite irons). **B. Key Elevated Temperature Performance Characteristics:** * **Maximum Continuous Service Temperature:** Up to **750°C (1382°F)**. * **Short-Term Peak Temperature:** Up to **850°C (1562°F)**. * **Superior Creep Strength:** The vanadium carbides provide exceptional resistance to slow, time-dependent deformation under sustained load at high temperature, a critical property for components like turbocharger housings and exhaust manifolds. * **High-Temperature Tensile Strength:** Retains a higher percentage of its room-temperature strength compared to non-vanadium grades at temperatures above 600°C. * **Excellent Thermal Fatigue Resistance:** Maintains good resistance to cracking under repeated thermal cycling, thanks to the combination of a ferritic matrix and stable carbide structure. * **Oxidation & Growth Resistance:** Excellent resistance to scaling and permanent volumetric growth due to the stable, adherent oxide layer and microstructure stability imparted by silicon and vanadium. --- ### **4. Product Applications** Meehanite HSV is specified for the most demanding high-temperature components, particularly where mechanical load and creep are major design considerations: * **Turbocharger Housings:** For heavy-duty diesel, marine, and high-performance automotive engines, especially in the high-pressure (HP) turbine section where metal temperatures and stresses are highest. * **Exhaust Manifolds & Components:** For advanced diesel and gasoline engines targeting higher exhaust gas temperatures (for improved emissions control and efficiency). * **Industrial Gas Turbine Components:** Non-rotating parts such as casings, diffusers, and nozzle rings. * **High-Temperature Valve & Pump Casings** in the power generation and chemical processing industries. * **Heat Treatment Furnace Hardware:** Fixtures, trays, and rails that must carry significant loads at extreme temperatures without distorting. * **Waste Heat Recovery Systems:** Components exposed to aggressive, high-temperature exhaust gases. --- ### **5. International & Relevant Standards** Meehanite HSV is a proprietary alloy. Its performance typically meets or exceeds the requirements of the highest-grade standardized heat-resistant ductile irons and may be supplied against custom material specifications. Key reference standards include: * **EN 1563:2018** - *Founding — Spheroidal graphite cast irons*. While no standard grade exactly matches the HSV composition, its performance is often benchmarked against and exceeds that of: * **EN-GJS-SiMo 5-1** (High-silicon molybdenum iron). * **EN-GJS-XSiCrMo 5-2-1** or similar alloyed grades for higher-duty applications. * **ASTM A897 / A897M-16** - *Standard Specification for Austempered Ductile Iron* (For comparison with ultra-high-strength ADI, though ADI is not typically for sustained high heat). * **ASTM A536** - Covers general ductile iron grades (Contextual reference). * **ISO 1083:2018** / **JIS G5502** - General SG iron standards. **Important Note:** For critical applications, Meehanite HSV is most commonly supplied against **detailed customer-specific material specifications** or internal foundry standards (e.g., "Meehanite HSV-550" or similar), which explicitly define the required chemical ranges, minimum mechanical properties at room and elevated temperatures, and acceptance criteria for microstructural quality. Collaboration with a licensed Meehanite foundry during the design phase is essential. -:- For detailed product information, please contact sales. -: Meehanite HSV Heat Resisting Cast Iron Specification Dimensions Size： Diameter 20-1000 mm Length <6632 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Meehanite HSV Heat Resisting Cast Iron Properties -:- For detailed product information, please contact sales. -:
