Welcome to Maduka Metals, your trusted partner in Abuja for high-performance materials. We are proud to supply the exceptional Grade Mar M247, a nickel-based superalloy bar and rod designed for the most demanding environments. This material represents the pinnacle of metallurgical engineering, offering a unique combination of strength and resilience that is perfectly suited for critical applications where failure is not an option. When you choose Maduka Metals, you are choosing reliability and superior quality for your most challenging projects.
The composition of Grade Mar M247 is a sophisticated blend, primarily nickel with significant additions of cobalt, chromium, and tantalum, strengthened by a high volume of gamma prime precipitates. This advanced formulation results in outstanding mechanical properties, including exceptional tensile and creep strength at extreme temperatures, often exceeding 1800°F. It also boasts remarkable resistance to thermal fatigue and oxidation, maintaining its integrity under stress and heat where other materials would rapidly degrade, making it a truly high-performance alloy.

Yes, Grade Mar M247 bar can be welded using appropriate welding techniques like gas tungsten arc welding (GTAW) or laser welding, but preheating and post-weld heat treatment are often recommended.
Yes, for welding Gr Mar M247 Bar, typically used consumables include Inconel 625, Inconel 718, or similar high-nickel alloys to ensure compatibility with its high-temperature and corrosion-resistant properties.
Grade Mar M247, primarily used for turbine blades, is generally resistant to galvanic corrosion due to its high alloy content. However, galvanic corrosion risk can arise when coupled with dissimilar metals.
The uses for Grade Mar M247 bar and rods are found in the heart of high-stakes engineering. They are essential for manufacturing turbine blades and vanes in aerospace jet engines and industrial gas turbines, where intense heat and rotational forces are constant. This material is also crucial for components in high-temperature furnaces, nuclear reactors, and the tooling for die-casting. Essentially, any application that demands unwavering strength and durability under severe thermal and mechanical stress is where Grade Mar M247 proves its invaluable worth.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
