Equivalent designations: UNS N05500 DIN W. Nr. 2.4375 Monel Monel K-500 Trade Name: UNS N05500; W.Nr. 2.4375 Form ASTM Rod, bar, sheet, wire and forging etc B 865 Chemical composition % Ni Cu Fe C Mn Si S Al Ti min 63.0 27.0 2.30 0.35 max 33.0 2.0 0.18 1.5 0.50 0.010 3.15 0.85 Physical properties Density 8.44 g/cm3 Melting range 1315-1350℃ Features:Monel K-500 combines Monel 400’s excellent corrosion resistance with greater strength and hardness as a result of adding aluminum and titanium and proper heat treatment to cause precipitation hardening. It is nonmagnetic at temperatures as low as -101℃. Monel K-500 has excellent dimensional stability which is very useful in high precision devices. Like Monel 400, it does not undergo ductile-to-brittle transition at cryogenic temperatures as low as that of liquid hydrogen. Its tensile and yield strengths increase while ductility and toughness are only slightly impaired. Applications:Chemical process pump and valve components; paper production pulp processing doctor blades and scrapers; marine engineering chains, cables, fasteners and springs; electronic components; and oil and gas production non-magnetic housings, pump shafts and impellers.
