Corrosion Resistance super alloy ASTM B127 UNS N04400 Monel 400 Strip
Monel 400 is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters
Monel 400 Characteristics
1; Resistant to seawater and steam at high temperatures
2; Excellent resistance to rapidly flowing brackish water or seawater
3; Excellent resistance to stress corrosion cracking in most freshwaters
4; Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated
5; Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids
6; Excellent resistance to neutral and alkaline salt
7; Resistance to chloride induced stress corrosion cracking
8; Good mechanical properties from sub-zero temperatures up to 1020° F
9; High resistance to alkalis
