(1) It has excellent tolerance to neutral salt and alkaline salt, and has long been the standard material for salt production [SCALE STEEL]system.
(2) It has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and is one of the few materials that can[SCALE STEEL] be in contact with fluorine, hydrofluoric acid and hydrogen fluoride or their compounds.
(3) Poor performance in highly oxidizing acids such as nitric or nitrous acid.In this environment, high chromium stainless steel should be considered.
(4) in sea water than copper alloy more corrosion resistance.
(5)The maximum temperature of continuous work in the air is generally about 600℃, and the corrosion speed is less [SCALE STEEL]than 0.026mm/ A in high temperature steam.
(6) According to the German VDTUV material table, can be used as a pressure vessel at -10~425℃;In the ASME[SCALE STEEL] Boiler and Pressure Vessel Code, the maximum temperature is 480 ° C.
(7)The strength in the annealing state is very low, can be improved by tempering treatment strength.
(8)Good processing and welding performance.
MONEL400 alloy is a corrosion resistant alloy with excellent comprehensive properties. In fluorine, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives, the alloy has excellent corrosion resistance.The alloy is widely used in Marine, chemical and other fields. Typical applications include: pumps and propeller shafts;Marine fittings and fasteners;Chemical equipment;Gasoline and fresh water tanks;Crude oil distiller;Processing vessels and pipes;Boiler feed water heater;The heat exchanger.
