Mourad Metals stands out as a trusted manufacturer and supplier of Rene 41 bars and rods, based in Tunis, Tunisia, and catering to demanding industrial sectors around the globe. Rene 41 is a high-strength nickel-based superalloy celebrated for its remarkable performance in extreme temperatures and under mechanical stress. At Mourad Metals, we prioritize precision in our manufacturing processes, employing advanced metallurgical techniques and rigorous quality control systems. The Rene 41 bars and rods we provide are known for their consistent dimensions, exceptional surface finish, and reliable performance. With a strong commitment to international standards and our customers’ needs, we deliver solutions tailored for critical applications where strength, durability, and thermal stability are paramount.
Rene 41 is a precipitation-hardened nickel-based alloy, with nickel as its primary element, complemented by chromium, cobalt, molybdenum, aluminum, and titanium as key alloying elements. A touch of carbon is added to boost strength and creep resistance. This alloy boasts impressive tensile and yield strength, outstanding fatigue and creep resistance, and good ductility at high temperatures, reaching up to about 980°C. Additionally, Rene 41 bars and rods are known for their strong oxidation and corrosion resistance, making them ideal for extended exposure to harsh thermal and mechanical conditions.

Yes, RENE 41 bar can be welded using suitable techniques like gas tungsten arc welding (TIG) or gas metal arc welding (MIG). Preheating and post-weld heat treatment are recommended for optimal results.
RENE 41 bars are available in sizes ranging from 6mm to 250mm diameter, with finishes including hot-rolled, cold-drawn, rough-turned, centerless ground, and polished options.
Yes, RENE 41 rods are susceptible to galvanic corrosion when coupled with dissimilar metals in an electrolyte, especially if the other metal is more anodic. Proper isolation is recommended.
These bars and rods find extensive use in the aerospace, defense, and power generation industries, thanks to their exceptional high-temperature strength and reliability. Typical applications include components for jet engines, parts for gas turbines, afterburner assemblies, fasteners, springs, exhaust systems, and high-temperature structural hardware. The alloy is also utilized in missile components, high-stress tooling, and thermal cycling applications. With its excellent resistance to creep, fatigue, and oxidation, Rene 41 is perfect for components that require a long service life in extreme heat and stress.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
