Product Details


Materials introduction

UNS N08825 alloy pipe is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The chemical composition of the UNS N08825 alloy pipe is designed to provide exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-iron stress corrosion cracking. Reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also variety of oxidizing substances such as nitric acid, nitrates, and oxidizing salts. the titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion.


Material properties and application

The resistance of UNS N08825 alloy pipe is a kind of general engineering alloy pipe. It has the corrosion resistance of acid and alkali metals in oxidation and reduction environment. High nickel content makes the UNS N08825 alloy pipe has effective resistance to stress corrosion cracking. It has good corrosion resistance in various media, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. The comprehensive performance of the UNS N08825 alloy pipe is shown in the Nuclear Combustion dissolver with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, which are treated in the same equipment. It can be used in all kinds of industrial fields, such as heating pipe, container, basket and chain used in sulfuric acid pickling plant, seawater cooling heat exchanger, marine product pipeline system, acid gas environment pipeline, heat exchanger in phosphoric acid production, evaporator, scrubber, impregnation pipe, air heat exchanger in petroleum refining, food engineering, chemical process, pressure oxygen application of flame retardant alloy etc
