Multimet N155 (UNS R30155 / W.Nr. 1.4971)
Multimet N155 (UNS R30155 / W.Nr. 1.4971) is a nickel-based alloy used predominantly in applications requiring strength, high temperature, and oxidation resistance. Multimet N155 can be treated to exponentially improve its temperature resistance and make it the perfect metal for tail pipes and cones, nozzles, and both turbine and afterburner components.
