Rupal Metals stands out as a leading manufacturer and supplier of Grade Mar M247 Bars and Rods, providing cutting-edge nickel-based superalloy solutions right from Delhi, India. Mar M247 is a remarkable precipitation-hardenable alloy made from cobalt, nickel, and chromium, celebrated for its outstanding high-temperature strength, resistance to oxidation, and durability against thermal fatigue. Rupal Metals offers precision-engineered Mar M247 bars and rods in a variety of sizes and finishes, all while adhering to strict quality standards. Catering to the aerospace, power generation, and turbine manufacturing sectors, Rupal Metals ensures that their materials perform reliably under the intense thermal and mechanical stresses found in critical engine components.
Grade Mar M247 is a nickel-cobalt-based superalloy that consists of about 10% cobalt, 15% chromium, 8% aluminum, 4.5% titanium, and 6% tantalum, along with other elements like molybdenum, iron, and carbon. This alloy showcases impressive high-temperature tensile strength (over 1100 MPa at 900°C) and remarkable resistance to creep and fatigue. It also maintains oxidation resistance up to 1100°C and exhibits excellent stability during thermal cycling. Mar M247 can be precipitation-hardened to achieve the high hardness and strength necessary for demanding aerospace turbine applications.

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.
Rupal Metals’ Grade Mar M247 Bars and Rods find extensive use in aerospace turbine engines, gas turbines, and power generation, where components are subjected to extreme temperatures and stresses. Common applications include turbine blades, discs, seals, and parts of combustion chambers. Thanks to its exceptional creep resistance, oxidation protection, and durability against thermal fatigue, this alloy is perfect for critical rotating and stationary components in jet engines and industrial turbines.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
