Situated in the industrial heart of Amman, Sabra Metals has built a reputation for delivering high-performance materials to demanding sectors across the globe. We take pride in providing specialized alloys like Grade Mar-M247, a premium solution for the most challenging engineering environments. Our inventory of Mar-M247 bars and rods is supplied with the assurance of rigorous quality control, ensuring that our clients receive a product that consistently meets the highest standards of reliability and performance right from the start.
Grade Mar-M247 is a nickel-based superalloy renowned for its exceptional strength at extreme temperatures. Its sophisticated composition includes significant amounts of cobalt, chromium, and tungsten, strengthened by tantalum and hafnium carbides. This complex formula grants it outstanding creep resistance and the ability to retain its mechanical properties, including high tensile and yield strength, even when exposed to prolonged periods of intense heat and stress, making it a material built for endurance.

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 remarkable capabilities of Mar-M247 make it indispensable in the most critical aerospace and industrial applications. You will typically find it in the hottest sections of jet engines and gas turbines, serving as vital components like turbine blades and vanes. Beyond aerospace, it is also the material of choice for high-stress parts in power generation equipment and specialized fixtures for high-temperature heat treating, wherever failure is simply not an option and performance under fire is paramount.
