LORK GROUP has been developing in the field of metal, stainless steel and alloy for more than 40 years, realizing the integrated supply chain management application from raw materials to deep processing and quality inspection, Professional Quality, Humanistic Lork, Scientific and Technological Future.
Monel R-405 (UNS N04405 / W.Nr. 2.4360, 2.4361 the free-machining version of Monel 400. A controlled amount of sulfur is added to the alloy to provide sulfide inclusions that act as chip breakers during machining. A Ni-Cu alloy with high strength and excellent resistance to a range of media including seawater, hydrofluoric and sulfuric acids, and alkalies. Used in marine and offshore engineering, chemical andhydrocarbon processing equipement, valves, pumps, shafts, fittings, fasteners, and heat exchangers.
Monel R405 Features
▪ Resistant to seawater and steam at high temperatures
▪ Excellent resistance to rapidly flowing brackish water or seawater
▪ Excellent resistance to stress corrosion cracking in most freshwaters
▪ Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated
▪ Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids
▪ Excellent resistance to neutral and alkaline salt
▪ Resistance to chloride induced stress corrosion cracking
▪ Good mechanical properties from sub-zero temperatures up to 1020° F
▪ High resistance to alkalis
Monel R405 Applications
▪ Marine engineering
