George Metals, located in Houston, USA, specializes in manufacturing and supplying Grade Mar M247 Bars and Rods, designed specifically for high-temperature applications in the aerospace and industrial gas turbine industries. Mar M247 is a nickel-based superalloy celebrated for its remarkable strength, resistance to creep, and stability against oxidation at elevated temperatures. Crafted through precise casting and heat treatment methods, our bars and rods adhere to the highest performance standards. George Metals offers Mar M247 in a range of diameters and specifications, perfect for critical components in turbine engines, combustion systems, hot section parts, and thermal processing applications where durability is essential.
Grade Mar M247 Bars and Rods from George Metals boast a meticulously balanced composition that includes nickel (the base), 8.4% cobalt, 10% chromium, 5.5% aluminum, 1% titanium, 0.7% molybdenum, 3% tantalum, and 10% tungsten, along with trace amounts of carbon, zirconium, and boron. This high-performance alloy delivers outstanding tensile and creep strength, with a service capability reaching up to 980°C (1800°F). It excels in oxidation and corrosion resistance during thermal cycling. Typically found in a precipitation-hardened state, Mar M247 is perfect for structural components that need to endure long-term thermal fatigue and maintain dimensional stability under high stress.
