Common Uses:
Equipment such as pumps, valves, compressors, bushings, and turbo-supercharger housings made of exhaust gas manifolds that can function at high temperatures up to 1000 K would benefit from superior weldability in their design and construction. These types of components are often used in applications where strong and reliable welds are important.
