Specifications:
General introduction
Alloy N-155 is an iron-based alloy with high strength resistance of up to 815°C (1500°F). It can sustain moderate loading at temperatures of 1093°C (2000°F). It has good oxidation resistance at high temperature and good corrosion resistance to sulfuric acid (at room temperature) and to nitric acid. This alloy’s high temperature strength is gained from its chemical composition rather than from age hardening.
