MARM200 nickel-based cast superalloys MARM246 and MARM247 alloy steel bar and steel plate
MAR-M247 is a nickel-based precipitation-strengthened cast superalloy designed for extreme high-temperature, high-stress, and complex corrosive environments. It is widely used in high-temperature components in aerospace, gas turbine, and energy fields.
MAR-M247 exhibits superior performance at high temperatures:
• Oxidation resistance: After long-term aging at 900℃ (up to 8000 hours), a multi-layered oxide film primarily composed of Al₂O₃ forms on the surface. Over time, the inner Al₂O₃ film becomes thicker, more continuous, and denser, significantly improving the alloy's oxidation resistance. However, the initially formed W-rich oxide layer may be porous and prone to peeling.
• Hot corrosion resistance: It exhibits good resistance to hot corrosion (such as sulfate deposition corrosion).
Heat Treatment Process
Heat treatment is crucial for maximizing the performance of MAR-M247. Typical specifications are as follows:
• Solution Treatment: Typically, heating and holding at 1200-1250℃ (e.g., 2-6 hours) aims to dissolve the γ' phase and certain carbides, obtaining a homogeneous supersaturated solid solution. Higher solution temperatures (e.g., 1260℃) help dissolve more primary γ' and eutectic phases, but strict control is required to prevent initial melting.
• Aging Treatment: A two-step aging process is employed. First, holding at 980-1100℃ (e.g., 5 hours) precipitates coarse γ' phases and improves carbide morphology; then, holding at 850-900℃ for an extended period (e.g., 20 hours) precipitates fine γ' phases, achieving peak strengthening and obtaining an optimal combination of strength and creep life.
