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.
Grade Mar M247 Bars and Rods find extensive use in high-temperature and high-stress settings where exceptional creep and oxidation resistance are essential. In the aerospace sector, they are utilized in turbine blades, nozzles, and combustor components for jet engines. Industrial gas turbines incorporate Mar M247 in hot section parts that operate continuously at elevated temperatures. This alloy is also well-suited for defense and marine propulsion systems, where high strength and resistance to thermal fatigue are vital. Its outstanding mechanical stability and corrosion resistance make it perfect for critical rotating and structural components that are exposed to harsh thermal and mechanical conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
