NS336 is a Ni-Cr base solid solution reinforced deformation superalloy with chromium, molybdenum and niobium as the main sosoloid strengthened elements. The maximum operating temperature is 950℃. The alloy has good tensile strength and fatigue resistance from low temperature to 980℃ and has good processing and welding technicality. The alloy has excellent corrosion resistance, oxidation resistance and stress corrosion resistance in salt spray atmosphere. Alloys have been used in the manufacture of aerospace engine casings, guide blades, mounting edges and barrels, fuel pipelines and etc components. The corrosion rate of the alloy is very low in both Marine and non-marine atmospheres and its corrosion resistance to seawater is very good. The alloy is resistant to the corrosion of various salting and has good resistance to the corrosion of nitric acid and phosphoric acid. It also has considerable resistance to the corrosion of hydrochloric acid and low concentration sulfuric acid when heated below boiling point. The aging hardening of the alloy after long-term use at 550℃~700℃ can lead to a decrease in the alloy plasticity . The main products are sheet, bar, pipe, wire, strip and forgings.
