Monel K500 N05500 prefabrication of Pipe Spools high strength corrosion fatigue and erosion resistance
When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.
Typical applications for alloy K-500 are pump shafts and impellers; doctor blades and scrapers; oil-well drill collars and instruments; electronic components; springs; and valve trim. This alloy provides excellent corrosion resistance in a range of environments including sea water, hydrofluoric acid, sulphuric acid and alkalis. It has found to be resistant to a sour-gas environment and is listed within NACE MR1075.
