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.
