Nickle Alloy disc, a thin, projecting metal stripattached to asemiconductor to dissipateheat. It is widely used incatering and kitchenware,elevators,chemical equipment,machinery manufacturing,architectural decoration, metaproducts, automobiles, pressurevessels and other felds
Monel 400 (UNS NO4400/W.Nr. 2.4360) is a nickel-copper alloy (about 67% Ni- 23% Cu) that is resistant to sea water and steam at high temperatures aswel as to salt and caustic solutions. Aloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloyexhibits characteristics like good corrosion resistance, good weldability and high strength. A low corrosion rate in rapidly flowingbrackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to avariety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.
Corrosion Data:
Monel alloy 400 offers great stress corrosion cracking in most freshwaters. Due to Copper it offers resistance to marine application ( salt water ), steam water even at high temperature. Good Resistance to hydrochloric acid , sulphuric acids while de-aerated. Resistance to Neutral & Alkaline salts. Resistance to chloride stress corrosion cracking.
