NS311

NS311 Introduction. Since the metal Ni itself has a face-centered cubic structure, its crystalline stability enables it to accommodate more alloying elements than Fe, such as Cr and Mo, to achieve resistance to various environments; at the same time, nickel itself has a certain degree of corrosion resistance, especially to stress corrosion caused by chloride ions. In strong reduction corrosive environments, complex mixed acid environments, and solutions containing halogen ions, nickel-based corrosion resistant alloys have absolute advantages over iron-based stainless steels

NS311's main features   Fluorine ion high temperature nitric acid corrosion, high oxidation resistance, non-magnetic   -Example of NS311 use   Non-magnetic components in high-temperature nitric acid environment and strong corrosive conditions   The composition of NS311 contains high concentrations of oxidation-prone alloying elements such as chromium, molybdenum, cobalt, titanium, etc. These oxidation-prone elements strengthen the alloy and the nickel metal itself becomes a harmful impurity element in the alloy, especially an important one. Sources of sulfur and phosphorus. The content of harmful impurities S and P in nickel-based high-temperature alloys should be less than 0.010-0.020%.
